HISPANIOLAN AND BAHAMAN ANNULARIIDAE 113 



summit and the periphery and one a little anterior to the suture. 

 Peristome white. Nuclear whorls 2, well rounded, microscopically granu- 

 lose, forming a rather small apex. Postnuclear whorls decidedly inflated, 

 strongly rounded, and marked by retractively curved, slender axial rib- 

 lets, of which 112 are present on the last turn. The spiral sculpture 

 consists of threads about as strong as the ribs, of which 14 are present 

 between the summit and the periphery. The junctions of the axial ribs 

 and the spiral threads form rounded nodules, while the spaces enclosed 

 between them are rectangular or squarish pits. Suture deeply channeled. 

 Periphery inflated, strongly rounded. Base short, inflated, strongly 

 rounded, broadly and rather openly umbilicated, and marked by the con- 

 tinuation of the axial ribs and 16 spiral threads. Sixteen additional spiral 

 threads are present on the umbilical wall. On the base and umbilical wall 

 the junction of the axial ribs and spiral threads also forms tubercles. 

 Last whorl solute for about one-fifth of a turn. Aperture broadly oval; 

 peristome simple, moderately broadly reflected, broadest at the junction 

 of the columellar and basal lip and narrowest on the parietal wall. Oper- 

 culum typically kisslingid. 



The type (U.S.N.M. No. 504084) was collected by W. J. Eyerdam in 

 woods on the mountain at Basin Sin, Massif du Nord, Hinche. It has 

 a little more than 6 whorls and measures: Height, 16.4 mm.; greater 

 diameter, 11.8 mm.; lesser diameter, 9.7 mm. 



Its turbinid shape will at once diflferentiate it from Kisslingia hahoru- 

 censis, which is of ovate outline. 



U.S.N.M. No. 379926 contains 154 topotypes from the same source. 



KISSLINGIA BAHOBUCENSIS, new species 



Plate 17, Figure 2 



Shell ovate, pale yellow, with interrupted spiral bands of brown, 

 which in part are arranged in both axial and spiral series and in part 

 irregularly scattered. The individual spots that make up these series are 

 also of irregular slant, except for the band at the periphery, which is 

 obliquely protractively arranged and quite regular and fairly regularly 

 spaced. The band at the summit contains the heaviest elements of color; 

 peristome white. Nuclear whorls 2, well rounded, microscopically granu- 

 lose, forming a small apex. Postnuclear whorls moderately well rounded, 

 marked by slightly retractively curved axial ribs, of which 147 are pres- 

 ent on the last turn in the type. These riblets are rendered slightly wavy 

 by the spiral sculpture, and they terminate more abruptly on the right 

 margin and slope gently toward the left; they are much more closely 

 approximated on the last tenth of the last whorl and smaller, which 

 materially increases the count. The spiral sculpture consists of weak 

 threads of which six are present on the second whorl and nine on the 

 third, while on the last turn they are rather obsolete. Suture narrowly
