Book Description
Excerpt from A Monograph of the Entomostraca of the Cretaceous Formation of England Of the numerous microscopic organisms afforded by the disintegration of the Oolitic, Cretaceous, and Tertiary strata, whether calcareous, argillaceous, or sandy, the Polythalamia and the Entomostraca are by far the most abundant. The latter attract observation by their larger relative size, but have not been hitherto very extensively described. Our present observations are confined to the Entomostraca of the Cretaceous Formation, comprising the Chalk, Chalk-marl, Gault, and Greensand. The strata that have afforded the species herein described are the greensand beds of Blackdown (siliceous), of Warminster (calcareous), and of Farringdon (arenaceous); the Speeton Clay; the Gault of Folkstone and of Leacon Hill, near Charing; the Grey Chalk and Chalk-marl of Dover; the Cretaceous Detritus of Charing; the Red Chalk of Flamborough; and the common White Chalk of the south-east of England. In the above-mentioned strata these little fossils lie about irregularly in all directions, and are not found in layers such as are often formed by the Entomostraca of the Wealden and Tertiary beds; many are broken or eroded, and some bear evidence of having been crushed whilst in a recent state. The animal matter of the carapace is well preserved in the Gault specimens, and more or less so in others; individuals bearing a trace of transparency and of original colouring occur, but are extremely rare, in the Chalk; whilst in the Gault a large proportion remains transparent. The specimens generally occur as separate valves, but perfect carapaces are not unfrequently found, the latter condition being dependent upon the strength of the hinge attachment, which varies considerably in different species.

Book Description
Excerpt from A Monograph of the Tertiary Entomostraca of England The Tertiary Entomostraca of Britain have hitherto received but little notice. In my 'Monograph of the Cretaceous Entomostraca, ' 1849, published by the Palaeontographical Society, I referred to the occurrence of some of the Cretaceous species in our Tertiary deposits. Dr. Reuss, about the same time, figured and described two forms which he had received from the Barton Clay of Hampshire; and I have since described a few species from Woolwich and Colwell. Several of the Post-tertiary fresh-water Entomostraca, however, have been noticed by me, in 1850, in the 'Annals of Natural History.' To these latter species I have now to add two others; and of the Tertiary Entomostraca I am enabled, from my own collection and with the aid of my friends, to enumerate 50 species; altogether amounting to 58 species. Of these, 30 (including three described by me in the 'Memoirs of the Geological Survey' whilst preparing this Monograph) are new. The Post-tertiary species are included in this Monograph for the sake of convenience, and to render the subject as perfect as circumstances will permit. The recent forms which have become fossilized in the Post-tertiary deposits, either of fresh-water, estuarine, or marine origin, not only complete the geological series up the present day, but are of considerable value in assisting us in the identification of some carapace-remains, otherwise obscure in their relations. The list of these later species of Ostracoda may be also regarded as a not uninteresting addition to the valuable resume of the Molluscan fauna of the Post-tertiary and Pleistocene eras, with which Mr. S. V. Wood has enriched his elaborate and valuable 'Monograph on the Mollusca of the Crag.' About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book Description
Excerpt from A Supplementary Monograph: Of the Tertiary Entomostraca of England The Tertiary Bntomostraca (Ostracoda) of England, at first treated of in a Monograph for the Palontographical Society in 1857, were revised by one of us in the 'Geological Magazine, ' 1870, pp. 155 - 159. The researches of G. O. Sars and G. S. Brady, with D. Robertson and others, elucidating the relationships of the genera and species among recent forms, gave effect in a great degree to that revision; and their continued labours have further helped us. Since the publication of the Revision, eighteen years ago, besides there being some additional corrections to be noticed, several new species have come to hand, late research in the fossiliferous deposits of Tertiary age having enabled our friends to add to the collections we have made for ourselves, so that the known English Tertiary forms are now upwards of one hundred in number. The British Post-Tertiary species are still more numerous. Some of the latter were described in the Monograph for year 1855 (dated on title-page 1856, but issued in 1857), and what relates to them in the new researches is here noticed. The notices and descriptions of revised and new forms will be arranged according to their alliances, and as far as possible in a Natural Order, in accordance with the grouping of genera adopted by Dr. G. S. Brady in his latest memoirs on recent Ostracoda. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
