Poey's description and figures are given. It is a more 

 slender species than 8. homalogyra, with the last two or three 

 whorls longer and even flatter, the upper slope of the last 

 whorl being almost impressed or concave. The striae are 

 quite strongly arcuate. 



I have seen no examples from the Isle of Pines, and feel 

 disposed to doubt the identity of any form from there with 

 the East Cuban 8. stricta. 



20. 0. BACILLUS (Pfeiffer). PL 30, figs, 7, 8, 9, 10. 



Shell imperforate, subulate, rather thin, slightly striat- 

 ulate, diaphanous, waxen; spire lengthened, almost regu- 

 larly tapering, the summit fine ; suture light, sometimes obso- 

 letely submarginate. Whorls 8 to 10, the upper ones convex, 

 the lower flattened, last whorl about two-ninths the total 

 length. Columella simple, very slightly twisted. Aperture 

 oblique, oblong-oval ; peristome simple, unexpanded, the right 

 margin slightly dilated forward. Length (largest specimen) 

 18.5, diam. 3.75, aperture 3.66x2 mm. (Pfr.). 



Eastern Cuba: between Demajagua and Guantanamo 

 (type loc.) ; Guantanamo, under stones (Gundlach) ; Bar- 

 acoa (Arango).
