Book excerpt: Excerpt from Preliminary Report Upon Invertebrate Fossils: Collected by the Expeditions of 1871, 1872, and 1873, With Descriptions of New Species Length of the body in proportion with the width variable; in some specimens (perhaps broken ones) the length and width being about equal, while in others the length is two or three times as great as the width. The width, in different specimens, varies from three and a half to upward of four centimeters. Position and locality. - Same as the last. Brachiopoda. Genus Acrotreta Kutorga. Acrotreta? Subsidua (sp. nov.) - Shell thin, corneous, discoid, subcircular or slightly suboval in outline, the transverse diameter being a trifle greater than the longitudinal; sides regularly and front broadly rounded; posterior margin slightly straightened, forming a comparatively short, slightly convex, or nearly straight hinge-line. Dorsal valve nearly flat; beak marginal, not prominent. Interior with a slightly-raised median ridge, beginning beneath the beak, and extending to about the middle of the valve, where it disappears; impressions of the posterior adductor muscles small and placed nearly beneath the beak, one on each side of the median ridge; between these muscular impressions and the posterior margin there is, at each side, an obscure diverging ridge or fold. Ventral valve moderately convex in the umbonal region, but more flattened anteriorly; apex excentric, somewhat prominent and minutely perforate; adductor impressions small and placed in the apex close to the foramen, one at each side of it. One of the specimens shows a slight flattening of the triangular space between the apex and the hinge-line, which appears like an indistinctly-defined cardinal area. This shell differs so widely in shape from the typical forms of Acrotreta, although it seems to possess its other essential characteristics, that I have referred it only provisionally to that genus. Length of the largest specimen, six millimeters; width, seven millimeters. Position and locality. - Strata probably of the epoch of the Potsdam Sandstone, Antelope Spring, House range, Utah. Genus Trematis Sharpe. Trematis Pannulus (sp. nov.) - Shell small, subcircular; ventral valve moderately convex; apex prominent, excentric; surface marked by a very fine net-work of oblique, raised lines, dividing it up into minute four-sided pore-like pits, which cause it to resemble, under a lens, finelywoven cloth. Diameter of the valve, about three millimeters. Position and locality. - Shales of the Potsdam epoch, Pioche, Nevada. Pteropoda. Genus Hyolithes Eichwald. Hyolithes Primordialis Hall? - The collection contains specimens of a Hyolithes from the shales of the Potsdam epoch at Pioche, Nev., that seem to differ too little from H. primordialis Hall, from the strata of the same epoch in Wisconsin, to warrant a full specific separation from it.

Book excerpt: Trieste Publishing has a massive catalogue of classic book titles. Our aim is to provide readers with the highest quality reproductions of fiction and non-fiction literature that has stood the test of time. The many thousands of books in our collection have been sourced from libraries and private collections around the world.The titles that Trieste Publishing has chosen to be part of the collection have been scanned to simulate the original. Our readers see the books the same way that their first readers did decades or a hundred or more years ago. Books from that period are often spoiled by imperfections that did not exist in the original. Imperfections could be in the form of blurred text, photographs, or missing pages. It is highly unlikely that this would occur with one of our books. Our extensive quality control ensures that the readers of Trieste Publishing's books will be delighted with their purchase. Our staff has thoroughly reviewed every page of all the books in the collection, repairing, or if necessary, rejecting titles that are not of the highest quality. This process ensures that the reader of one of Trieste Publishing's titles receives a volume that faithfully reproduces the original, and to the maximum degree possible, gives them the experience of owning the original work.We pride ourselves on not only creating a pathway to an extensive reservoir of books of the finest quality, but also providing value to every one of our readers. Generally, Trieste books are purchased singly - on demand, however they may also be purchased in bulk. Readers interested in bulk purchases are invited to contact us directly to enquire about our tailored bulk rates.
