CUBAN SUBFAMILY CHOXDROPOrvIIXAE TOKRE AXD BARTSCH 247 



The type, U.S.N.IM. no. 468852, has almost four whorls remaining 

 and measures: Length, 20.2 mm: greater diameter, 12.0 mm; lesser 

 diameter, 9.3 mm.

 Plate 14, Figubf. 4 



In this race the shell is marked by almost continuous, strong, brown 

 spiral bands on both spire and base. These bands extend upon the 

 peristome, which they mark radially; the rest of the peristome is 

 white. 



The type, U.S.N.M. no. 492719, we collected on the Tomas Barrera 

 Expedition at Sagua, Pan de Guajaibon. It has 5 whorls remaining 

 and measures: Length, 23.4 mm; greater diameter, 12.2 mm; lesser 

 diameter, 9.3 mm. 



The strong spiral banding and the absence of axial brown streaks 

 characterize this subspecies.

 Proc. U. S. Nat. Miis., vol. 58, p. 187. 



This race has the shell bright orange-red, unicolor or faintly inter- 

 ruptedly spirally banded. The peristome is of a little paler orange 

 red color. It comes from Hato Caimito. 



The specimen figured, U.S.N.M. no. 492718, was collected by Gund- 

 lach. It has 4.7 whorls remaining and measures : Length, 23.0 mm ; 

 greater diameter, 12.8 mm ; lesser diameter, 8.8 mm. 



The absence of strong interrupted spiral bands or dark axial streaks 

 easily differentiates this from the other known subspecies. 



TURRITHYRA (TURRITHYRA) DECEPTOR (Aiango) 



Shell elongate-turreted, ranging in coloration from flesh-color to 

 bright rose-red, unicolor or marked by interrupted spiral threads of 

 brown. The axial ribs are frequently of much lighter color than the 

 rest of the shell. Peristome white, red, or reddish. Nuclear whorls 

 2, well rounded, smooth. Postnuclear whorls well rounded, marked 

 by sublamellar, retractively slanting axial ribs which extend over the 

 somewhat inflated and well-rounded periphery and base of the last 

 whorl into the moderately open umbilicus. In addition to this sculp- 

 ture, the whorls on spire and base are marked by numerous fine spiral
