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 imier half, but becoming 
more and more angulated, and sometimes quite angular above toward the 
aperture, with the swnmit 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 
8; 
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 Volutomorpha, but it can not be possible that it is congeneric with
