Sinopsis

Excerpt from Manual of Conchology, Vol. 17: Structural and Systematic, With Illustrations of the Species

IN discussing the African achatinidze the Author enters an unfamiliar field. The great Powers of Europe, England, Germany and France have made a large part of African soil their. Own; and the molluscan spoils gain-ed by soldier, ex plorer and missionary have been made known to science by English, French and German conchologists. Many of the more recently described species have been collected but once, and are to be found in a single museum. Under these cir cumstances it will be understood that in the treatment of species the views of such masters of the science as Eduard von Martens, Edgar A. Smith, J. R. Bourguignaft, Arthur More let and others have been adopted, and their works freely quoted. In larger matters of classification the author has felt upon more familiar ground, and several reforms, notably the dismemberment of the genus Achatina, are submitted for the consideration of malacologists. The attention of those ob taining African material is earnestly directed to the fact that only two or three genera of African Achatim'dw are alde qu-ately known anatomically, and almost nothing is known of some of the commonest West and South African genera.
