HISPANIOLAN AND BAHAMAN ANNULARIIDAE

The type (U.S.N.M. No. 504057) comes from Corail, Haiti. It has 

 4.6 whorls remaining and measures : Height, 14.7 mm. ; greater di- 

 ameter, 8.2 mm. ; lesser diameter, 6.0 mm. 



SAliIxEPOMA VACHENSE, new species 



Plate 20, Figure 4 



Shell very elongate-ovate, pale yellow, with narrow interrupted spiral 

 bands of brown, the elements of which are arranged in both axial and 

 spiral series. Of these, six are present between summit and periphery 

 and three on the base. Nuclear whorls decollated in all our specimens. 

 Postnuclear whorls well rounded, slightly shouldered at the summit, and 

 marked on the early whorls by slender axial riblets, which become broad 

 and round on the last turn. Sixty of these are present on the last whorl. 

 Suture well constricted. Periphery well rounded. Base moderately long, 

 well rounded, decidedly openly umbilicated, and marked by the con- 

 tinuation of the axial ribs, which extend over the umbilical wall; the 

 latter bears six spiral threads. The last whorl is solute for about one- 

 fifth of a turn. Aperture oval; peristome double, the outer moderately 

 broadly expanded, widest at the junction of the basal and outer lip and 

 at the auricle at the posterior angle and narrowest on the parietal wall; 

 the inner strongly exserted and slightly reflected. Operculum typically 

 sallepomid. 



The type (U.S.N.M. No. 504058) was collected by Orcutt at lie a 

 Vache, Haiti. It has 3.3 whorls remaining and measures: Height, 

 12.8 mm. ; greater diameter, 7.3 mm. ; lesser diameter, 6.3 mm. 



U.S.N.M. No. 442863 contains 2 topotypes, which vary widely in 

 measurements from the type. I therefore also cite these: 



SAI1I.EPOMA OCCIDENTAL.E, new species 



Shell elongate-ovate, pale yellow, marked by interrupted spiral bands 

 of brown on spire and base. Nuclear whorls decollated in all our speci- 

 mens. Postnuclear whorls inflated, strongly rounded, very narrowly 

 shouldered at the summit, and marked by almost vertical, retractively 

 curved axial riblets, which vary decidedly in strength in the two sub- 

 species. Suture strongly constricted. Periphery well rounded. Base mod- 

 erately long, openly umbilicated, and marked by the continuation of the 

 axial ribs, which extend feebly over the umbilicus that bears several 

 spiral threads. Aperture broadly oval; peristome double, the outer flar- 

 iagly expanded, broadest at the junction of the inner and basal lip and
