Book excerpt: Excerpt from The Danish Ingolf-Expedition, Vol. 5 The paper on the Actiniaria, of which I now present the first part, has been drawn up according to the same plan as my reports on the Ceriantharia and Zoantharia of the Ingolf-Expedition. The main part of the material examined by myself belongs to the museums in Copenhagen and Stockholm. I have had at my disposal a rather great collection mainly enclosing the forms dredged by Romer and Schaudinn during their journev around the Spitzbergen, and I have also examined smaller collections from the museums in Upsala, Gothenburg, Lund, Christiania, Bergen, Drontheim, Tromso, Francfort on the Main and Petrograd. I beg to express my best thanks to all, who have supported my work through lending of material. The paper on the Ingolf-Actiniaria will be divided into four sections: 1) Description of the species. 2) Survey of the literature with critical notes on the arctic and northern Actiniaria. 3) Distribution of the species. 4) Contribution to the anatomy, genealogy and classification of the Actiniaria. In the present paper I have described all families occurring in the arctic and northern waters excepting the forms which have been referred to the old family Sagartiidae. I have given special attention here to the size and distribution of the nematocysts and spirocysts. As before emphasized by me the stinging capsules are of great importance to the classification. Nearly related genera show great agreement in the appearance and distribution of the nematocysts, and the species are often characterised by the different sizes of these latter, though in many cases the differences are not great. In fact I think that it is impossible to put up a good system of the Actiniaria without considering the stinging capsules. Concerning my statement of the breadth of the stinging capsules I will remark that it is approximate. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book excerpt: Excerpt from The Danish Ingolf-Expedition, Vol. 5: Ctenophora On my asking Sir John Murray, whether it might be possible to get some specimens of these Planarians for examination, he kindly applied to the British Museum about the matter, and I had the pleasure to receive some specimens found among Crustaceans from that station. The examination of these specimens certainly left no doubt that they were really Planarians. The matter is, however, not definitely settled thereby. The specimens examined had no tentacles or processes, so that they could not have been described as having digitiform processes or a superior penis. It seems then not un reasonable to suppose that there have really been some Coeloplmza among the Planarians, which have, however, become 'lost on account of the difficulty of preservation.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Danish Ingolf-Expedition, Vol. 1 According to the Financial Law of 1894 - 95, a sum of 30,000 Kroner was voted on the budget of the Ministry of Public Instruction for preliminary arrangements for a Danish scientific deep-sea expedition by the cruiser Ingolf for exploration of the Arctic seas around Iceland and Greenland, zoological collections being the principal object of the expedition. The expedition was to be made in two voyages of 4 months each, respectively in 1895 and 1896. On the 12th of April 1894, I received a communication from the Ministry of Public Instruction to undertake the necessary arrangements for the expedition together with professor Lutken, and on the 16th of the same month, I received another communication from the Ministry of Naval Affairs to inform me that I was appointed captain of the cruiser Ingolf and Leader of the expedition. The Ministry of Naval Affairs placed the cruiser Ingolf at disposal with officers and crew for the above purpose. Further on negotiations were entered into with the Naval Dockyard, and from these resulted that the principal alterations and fittings that had to be performed were as follows: Building of a deck-house aft with 3 cabins, a large one for the zoologists of the expedition, and two smaller ones, one of which for the physicist and the other for the botanist; fitting of a steam-winch with appertaining reel for the steel-wirerope; a reel for the thermometer-line; a trawl-boom with appurtenances, trawl and dredges as well as weights for soundings. The Ministry of Naval Affairs was not in favour of any alterations being made in the accommodation and fittings below deck, nor were any alterations in this respect necessary.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Danish Ingolf-Expedition, Vol. 5: 6. Hydroida (Part I) The investigation of the large Danish collections of hydroids from the Faroe Islands, Iceland and Greenland, and the researches into the interesting material brought home from the Ingolf Expedition, have realised great results. In fact, several points of dispute as to the classification of northern species have been settled. In the first place, the Danish collections contain original specimens of some species which have been described as new several times after being originally recorded. In other cases, the large number of specimens tend to bridge the division between species which have hitherto been looked upon as good ones. It is, indeed, a matter of regret that deficiencies of diagnosis and inaccuracy of design have frequently put obstacles to the recognition of species previously recorded, and that the literature has, consequently, been encumbered with synonyms which we should rather have done without. This inconvenience, in fact, enforces the necessity of giving full and exhaustive accounts of every single species. The American investigators, indeed, on the pattern of Nutting have long tried to give brief diagnoses and drawings of all American species. But it must be observed that, because of the impressionist way of drawing, the illustrations are, as a general rule, somewhat wanting in accuracy, and to the brief diagnoses there is the objection that they are often too summary to give exhaustive account of the distinguishing features. On the whole such weak points as appear in the last works of Allman, have gone down to his epigones. Great difficulties, indeed, are in this way given to students of the geographical distribution of the hydroids. No doubt, more species than those which are at present pointed out by literature, are common to the European and the American seas. But in general it proves impossible to form, on the ground of the brief diagnoses, a well-founded opinion as to the virtual qualities of many species. As far as the European species are concerned, we are fortunate in possessing the classic work of Hin ck s, A History of the British Zoophytes. However, since the appearance of that work, plenty of fresh subjects have been added by descriptions of several species and genera which can hardly all be maintained, and publications have of late appeared in such abundance that. It proves difficult to students of this group of animals to find their way through the crowded matter. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Danish Ingolf-Expedition, Vol. 2: 5. Lamellibranchiata (Part I) The Danish Ingolf - Expedition of 1895 - 96 brought home a very considerable material of Mollusca from the waters round the Faeroes, Iceland and South Greenland. The Expedition was planned on the lines of a deep-sea investigation and the greater part of the material collected comes therefore from great depths; of the 144 stations investigated no less than 125 have depths of over 100 fathoms. This material is naturally of great interest; the area investigated was but little known before and an extension of our knowledge of the deep-sea fauna must be classed among the relatively rare occurrences. Whilst working up this material I felt appreciably the lack of information regarding the distribution of the Mollusca in the coastal regions round a great part of the area. This does not apply however to Greenland; on the west coast of that country collections have been made for many years and the material has been worked up by H. J. Posselt, and from the east coast the gatherings of the expeditions of recent years have been worked up by Posselt, R. Héigg, Ad. S. Jensen and J. Grieg. From Iceland and the Faeroes, on the other hand, we had, just as previously for Greenland, but incomplete and short lists of the species and, as these, mainly drawn up by O. A. L. Morch.

Book excerpt: Excerpt from The Danish Ingolf-Expedition, Vol. 5 of 5: Contents, Hjalmar Broch, Stylasteridae, Published at the Cost of the Government The close examination of the Hydrocorallines meets perhaps with more difficulties than the study of the skeleton-bearing Hexacorallia, owing partly to the porous skeleton of the colonies, partly to the delicate nature of the organisms. The characteristics can be determined roughly by means of Dr. Koch's detailed method in which thin sections of the colonies are prepared by grinding with the stained soft parts in situ. The structure of the skeleton can also in part be studied by breaking the colonies as Hickson (1912 p.891) seems from the following remark to have done. The way in which it is possible to study the shape of the gasteropore styles is to make a vertical fracture in a plane parallel with the long axis of a branch. In a large percentage of such fractures the whole length of at least one gasteropore with its style will be exposed. It is evident however, that this method is not suited to form the base of a more thorough and systematic investigation of the skeletal parts of the colon). Where it is necessary for the observer to make his results free from chance irregularities he must have recourse to the somewhat slower method of grinding. In the present studies this latter method has throughout been used in the examination of the skeleton. The soft parts are first removed by means of Eau-de-Labarraque, and pieces of the colony have then been ground down on a fine and level whetstone as far as seemed necessary in each single case. For general systematic work it is usually sufficient to grind down a branch to about its median longitudinal plane; in a Stylaster, for example, the majority of the gasterostyles will in most cases appear quite free in the middle of the gasteropore. On the finely polished ground surface it will also be possible to study the course of the fine canals. Where there is question of examining the finer structure of the calcareous skeleton, however, this procedure is not sufficient and it is necessary in addition to have thin sections of the same kind as the geologists use in their studies. Since Moseley's fundamental work on the Hydrocorallines appeared in 1881 investigators have mainly directed their attention towards unravelling the features of the skeleton of the colonies. Excluding a couple of smaller papers on the gonophores of a few species, no observer since that time has sought to penetrate deeper into the organisation and finer structure of the Hydrocorallines. The result is, that we cannot yet be said to have full knowledge of their affinities and thus of their systematic position, a matter I shall return to later.
