Shell above a medium size, very ventricose and ponderous in charac- 
ter; height of shell and transverse diameter nearly equal, or higher than 
wide; spire low conical, the entire shell consisting of about four volutions; 
those of the spire convex, and the last one angulated above and truncated 
below; round ventricose, or short pyriform on the inner half, but becoming 
more and more angulated, and sometimes quite angular above toward the 
aperture, with the summit slightly concave; columella twisted, so far as 
can be determined from the casts examined; aperture large, subangular ~ 
above and broad below, with apparently a wide and deep anterior channel; 
surface of the volutions marked by strong, distant, node-like elevations on 
the upper part, which are extended below in the form of irregular vertical 
folds, visible to near the base of the volution. 
Mr. Gabb describes the columella as having a single heavy oblique 
fold, which I have not seen. The shell, as shown by the casts, is almost a 
counterpart of the living Voluta (Cymbiola) Braziliana Solander (— V. Cola- 
cynthus Chemn.) from the southern Atlantic coast, except that the upper 
volutions are more elevated and ventricose. Mr. Gabb* cites this as a 
species of Volutomon ‘pha, but it can not be possible that it is congeneric with 
procs a Nat. Sci., Phila., 1876, p. 290,
