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.
