CUBAN ANNULAKIIDAE — TORRE AND BARTSCH 343 



Aperture almost subcircular ; peristome double, the inner slightly 

 exserted and slightly reflected; the outer broadly expanded on the 

 outer and basal lip and narrower on the parietal wall, decidedly auricu- 

 lated at the posterior angle and very strongly fluted on the inner lip, 

 marked by a series of concentric laminae. Operculum typically 

 annularid. 



The specimen described and figured, U.S.N. M. No. 10995, is one of 

 6 coflected by C. Wright at La Catalina, Sagiia de Tanamo, Oriente 

 Province. It has a little over 4 whorls remaining and measures: 

 Length, 8.5 mm.; greater diameter, 4.4 mm.; lesser diameter, 3.4 mm.

 U. S. Nat. Mus., vol. 58, p. 67. 



Shell small, elongate-conic, pale yellow. Nuclear whorls 2, inflated, 

 strongly rounded, microscopically granulose, forming a pupoid apex. 

 Postnuclear whorls somewhat inflated, strongly rounded, marked by 

 rather strong, slightly retractively curved, axial riblets, which become 

 slightly expanded at the summit, or several of them may become fused 

 to form a hollow cusplike element. These ribs are not of the same 

 strength, but at irregular intervals they become intensified, with 

 smaller ribs between them, which gives the sheU a somewhat scalari- 

 form appearance. The riblets are nodulose at regular intervals, which 

 gives the shell the appearance of having spiral cords, a fact not borne 

 out in the intercostal spaces. Of the axial ribs 31 are present on the 

 first whorl and 88 on the last turn. Suture strongly constricted. 

 Periphery weU rounded, marked by the continuation of the axial 

 ribs, which cross the base, which is marked by 3 rather strong spiral 

 cords, which form narrow, well elevated tubercles at their junction 

 with the axial ribs. Last whorl solute for one-fourth of a turn, with- 

 out spiral sculpture on the umbilical wall. Aperture broadly oval; 

 peristome double, the inner moderately exserted and reflected; the 

 outer broadly expanded except at the parietal wall, somewhat fluted 

 and slightly denticulated at the edge. 



The specimen described and figured, U.S.N.M. No. 355386, is a 

 cotype received by Dr. de la Torre from Jeanneret who secured it on 

 Monte Libano, near Guantdnamo City, Oriente Province. It has 5.1 

 whorls remaining and measures: Length, 7.7 mm.; greater diameter, 

 3.4 mm.; lesser diameter, 3.0 mm. 



We have quite a series of specimens from the same region, which 

 were collected by Henderson and Bartsch.
