Book excerpt: Excerpt from The Danish Ingolf-Expedition, Vol. 6: Published at the Cost of the Government by the Direction of the Zoological Museum of the University The skeleton is chiefly of the same structure as in the foregoing species, and built upon the principle which upon the whole is found in the Longitudinal fibres (primary fibres) run longitudinally through the sponge, and spread to all sides like a sheaf, reaching to the surface where thev' project a little; they are united by transverse fibres (secondary fibres) into a rather regular net work. Far the greater part of the longitudinal fibres are polyspicular, but with far fewer spicules than in the foregoing species, and also unispicular fibres are seen; otherwise the fibres are somewhat different with regard to their thickness and the number of spicules, the thickness being about between the thickness of a spicule and and the distance between the longitudinal fibres is ca. 0'12mm thus the fibres are considerably thinner and the reticular work finer than in the foregoing species. Neither do the transverse spicules here form coherent fibres, but reach only from one longi tudinal fibre to the next, and are for a great part formed of but one spicule; in the inner part of the sponge they are far from each other, so that the meshes are more or less rectangular, but towards the surface they are nearer to each other, and here the meshes are more or less quadratic. The spongin is not bv far so strongly developed as in the foregoing species, and most frequently it forms no distinct sheath or only a very thin one round the spicules of the fibres; in the nodes it is distinctly seen; the transverse spicules are not generally quite surrounded by spongin, but only cemented at the ends. Besides the skeletal tissue thus constituted, some fibres are seen here and there running longitudinally along the branches without going to the surface, which fibres may divide and anastomose; they are a little stronger than the regular longitudinal fibres, and have more spongin forming a distinct sheath. Towards the base of the sponge the amount of spongin is greater, and the spicules of the fibres are here surrounded by a distinct spongin-sheath. In the hard, solid stalk the amount of spongin is verv considerable, and at the same time it passes from colourless to yellow; the intervals between the fibres are here very small, and the whole mass forms a very solid tissue.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Danish Ingolf-Expedition, Vol. 6: 2. Porifera (Part II.); Desmacidonidae (Pars.) Besides the division into chelae and ancorm Levinsen, in the paper quoted, subdivides chela into two forms, chelae palmatae and arcuatae. The former have a straight, or most frequently only slightly curved. Shaft, and rather large alae forming together an almost triangular or oval plate, often with a deep notch below; the tooth is often rather broad. In the other form, chelae arcuatae, the shaft is most frequently rather strongly curved, the alae are highly indented below and only attached to the shaft for a comparatively short way, thereby getting a somewhat tooth-like appearance; the tooth is most frequently rather narrow. To be sure, these two forms are not principally different, but differ only in form, and forms may also be met with that may only with difficulty be referred to either of them; but generally they form two well-marked groups, and are also characteristic for certain genera. Therefore there is every reason to keep this division. 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. 6: 3. Porifera, (Part III.) Desmacidonid (Pars.) The skeleton. The dermal skeleton; the skeleton formed by the dermal spicules is not much developed, it consists of larger or smaller bundles of dermal spicules lying in the membrane, partly horizontally, partly more or less erect in the somewhat thick dermis; besides the bundles more scattered and single spicules may also occur, but they are on the whole scarce, and large parts of the membrane may be seen without dermal spicules. At the base of the papilla they are present in greater numbers, and from here they stretch out in the wall of the papilla and form the skeleton of the papilla as mentioned above.' The main skeleton is a rather diffuse and irregular, multispicular reticulation in which primary and secondary fibres cannot be discerned; also single spicules are in many places seen to contribute to the skeleton. In the points of union is seen a distinct and rather rich amount of spongin which may also sometimes be seen to continue along the fibres.
