Shell large, cylindroconic, varying in color from soiled wax colored 

 to bright rose colored. The nucleus is small, consisting of 2 whorls, 

 which are well rounded and smooth. The postnuclear whorls are 

 flattened, somewhat constricted a little below the suture, and marked 

 by closely approximated, low, rounded axial riblets, which become less 

 conspicuous as the whorls increase. Suture only slightly constricted. 

 Periphery well rounded. Base slightly protracted, narrowly 

 umbilicated, and marked by an obsolete fold at the outer edge of the 

 umbilicus. Aperture subcircular; peristome not in one plane, but 

 someAvhat sinuous, simple, not thickened as in typical Farcimen. 

 Operculum typically farcimenid. 



The specimen figured, U.S.N.M. No. 535945, has 6.5 whorls remain- 

 ing and measures : Height, 39.1 mm. ; greater diameter, 14.7 mm. 



This is the common large race distributed all over the north coast 

 of the Island of Puerto Eico. 



I found the adult animal of this to have the forehead, sides, and back 

 brown with an olivaceous tinge, the foot flesh colored, with a bluish 

 tinge, tentacles tipped with orange. 



The young were flesh colored, with a red spot under the tentacles.

Shell small, elongate-ovate, varying in color from pale wax yellow 

 to chestnut-brown on the last turn. Nuclear whorls 2, well rounded, 

 smooth. The early postnuclear whorls are strongly rounded; the 

 rest with a constriction below the summit and marked by closely 

 spaced, slender, retractively slanting axial riblets, which become 

 obsolete on the last whorl. Suture slightly constricted. Periphery
