 Michel, Haiti. It is a complete specimen having 6 whorls and measures : 

 Height, 14.5 mm.; greater diameter, 11.8 mm.; lesser diameter, 8.7 mm. 



The turbinid outline will readily distinguish this from the other 

 licinids.

LICINA CAYEMITENSIS, new species 



Plate 19, Figure 2 



Shell elongate-ovate, the early whorls plum colored, the later brown; 

 tip pale. Nuclear whorls 2, well rounded, microscopically granulose, 

 forming a minute apex. Postnuclear whorls moderately well rounded, 

 narrowly shouldered, and marked by retractively curved axial riblets, 

 which are strongest and more distantly spaced on the early whorls and 

 become weaker and more closely approximated on the later turns. Of 

 these axial riblets, 194 are present on the last whorl. They extend over 

 the base and feebly upon the umbilical wall. The spiral sculpture con- 

 sists of slender threads that are weaker than the axial ribs; of these, 16 

 are present between the summit and the periphery of the last whorl, 12 

 on the base, and 20 on the umbilical wall. The spiral threads on the base 

 and umbilicus are stronger than those on the spire. The junctions of the 

 axial ribs and the spiral threads form feeble nodules on the early turns 

 and weaker ones on the remainder. Suture narrowly, deeply channeled. 

 Periphery strongly rounded. Base moderately long, well rounded, openly 

 umbilicated. Aperture oval; peristome double, the outer narrowly ex- 

 panded and rather thickened and slightly reflected, marked by con- 

 centric lines of growth and adnate to the preceding turn at the parietal 

 wall; the inner, somewhat thickened, slightly exserted and reflected. 

 Operculum typically licinid. 



The type (U.S.N.M. No. 504081) comes from Grande Cayemite 

 Island, Haiti; it has 5.5 whorls remaining and measures: Height, 

 25 mm. ; greater diameter, 14.9 mm. ; lesser diameter, 12.0 mm. 



U.S.N.M. No. 380329 contains 286 topotypes.
