Soft cover. Condition: Good. 1907, pp23-54, plus two plates. Removed from PROCEEDINGS OF THE UNITED STATES NATIONAL MUSEUM, VOLUME XXXI, 1907. VG. In plastic report covers. From the introduction: "The paper submitted herewith forms the first installment of a series of articles describing the Schizopod collections in the United S…tates National Museum. It treats of the families Lophogastridae and Eucopiidae, which consist almost exclusively of deep-sea forms. The material at hand, chiefly in the genus Gnathophausia, is so rich that it has been possible to prepare a complete revision of that genus, and it has been found that some characters, which were regarded hitherto as of specific value, are but differences of age in the same species.".

Paperback. Condition: New. Print on Demand. This book examines the distinct anatomies of mussels by studying the various gills of over 400 individuals within 15 different genera, classifying them into different groups using this information. The author argues that this detail can be used not only to more scientifically delineate… certain groups of mussels but also to better understand the development and overall biology of the mussels. The author also challenges some previously held scientific conventions by meticulously examining the mussels in his study and providing significant evidence to back up his new proposals. Ultimately, this book makes an important and unique contribution to our understanding of the evolution, and anatomy of mussels and is a fundamental text for scientists working in this area. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.

Paperback. Condition: New. Print on Demand. This book is a complete historical and scholarly analysis of the freshwater mussels of Pennsylvania, a group of mollusks comprising clams and mussels. Covering 32 species and their varieties, the author meticulously dissects the external anatomy of each species, using highly detailed d…escriptive language and images. Freshwater mussels are filter-feeders, acting as an important part of their ecosystem, providing food for fish, birds, reptiles, and mammals. Many of these mussels are endangered and threatened, and the author takes a deep dive into the challenges they face for survival and reproduction, including habitat destruction and pollution â" information that is particularly relevant in today's climate. This text provides deep insight into the conservation status of freshwater mussels and the protective measures needed to secure their future in Pennsylvania. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.
