NEW PUBLICATIONS. 
MIssIoN SCIENTIFIQUE au Mexique et dans ? Amerique Centrale, 
Etudes sur les Mollusques terrestres et fluviatiles, by M M. P. Fischer 
and H. Crosse. The fascicle of this magnificent work last issued 
contains part of the Cyclophoride and the Cyclostomatide, with 
several plates illustrating the Ampullariide. Of particular interest 
is the discussion (p. 148-150) of the genus Cyclotus. The authors 
purpose the name Neocyc/otus for a genus to comprise all of the 
American Cyclophoride with sharp lip and solid calcareous many- 
whorled operculum ; these shells have heretofore been called Cyclotus 
in American collections. The anatomy is fully worked out. The 
following groups of exclusively Mexican species are also fully 
described and illustrated: Tomocyclus C. & F. (containing Mexican 
species formerly referred to Megalomastoma), Habropoma C. &. F. 
and Amphicyclotus C. & F. (for species referred by previous authors 
to Cyclophorus). The plates, drawn by Arnoul, are superb. Messrs. 
Fischer and Crosse are to be congratulated on the progress of this 
magnificent work, indispensable to students of the tropical Ameri- 
can fauna.—P.
