Synopsis
Excerpt from Manual of Conchology, Structural and Systemic, Vol. 5: With Illustrations of the Species
Species, While organisms apparently quite diverse may be treated as varieties, simply because they are united by a series of intermediate forms.
In cases Where I have no specimen of a species, I have given a translation of the original diagnosis, followed by the name of the author from whom it is taken, together with any additional inform ation I have been able to obtain concerning it.
Anatomical details have been omitted because the preceding vol umes of Helix lack them. Under these circumstances it is more convenient to present all of this part of the subject in one place. The final volume treating of Helices will therefore contain besides other matter, a résumé of the anatomy of each subgenus of the Helices. Collectors having either fresh or alcoholic material for sale or exchange are invited to correspond with the author.
In the preparation of the present volume the author has been peculiarly fortunate in the Opportunities for study afforded by a collection of West Indian Land shells perhaps the largest in exist ence; the extensive collections of robert swift and of A. D. Brown having in recent years been united to the already large suites received by the Academy from poey, arango, bland, wright, redfield, and other workers in this fauna.
