 Bulimulus (Drymceus) bahamensis BENDALL, Proc. Malac. Soc. 

 Lond. i, p. 293. 



Bendall found it on trunks of cocoanut palms. It is closely allied 

 to D. immaculatus of Jamaica, although rather more elongated and 

 without the basal pink tint common in that species. 



For Haitian references see D. sallei var. haitensis. I have not seen 

 specimens from Durham Creek, Great Inagua (Sargent), which are 

 on record. 



D. ERUBESCENS (Pfeiffer). PL 13, fig. 89. 



Shell perforate, oblong-turreted, thin but moderately solid, whitish- 

 flesh or yellowish-flesh colored, becoming pink or pinkish-brown above; 

 surface rather dull, smooth, showing faint growth-lines and indistinct, 

 fine, spiral lines under the lens. Spire much elongated, apex sub- 

 acute, with typical Drymceus sculpture. Whorls about 6, nearly flat. 



Aperture less than half the length of the shell, oblique, pinkish 

 inside, peristome thin, the outer and basal margins somewhat ex- 

 panded, columella oblique, slightly twisted above, its edge reflexed 

 above. 



Alt. 29, diam. 11, length of aperture 13 mill. 



Alt. 21, diam. 8, length of aperture 10 mill. 



Alt. 24, diam. 10, length of aperture 12 mill.

Bulimus erubescens PFR., P. Z. S., 1846, p. 112; Monogr. ii, p. 

 44; vi, p. 57. REEVE, Conch. Icon., pi. 57, f. 381. 



The exceptionally slender form and ruddy color of the spire are 

 characteristic. Probably Gray's B. rufescens belongs here. It is 

 known only by the following description : 



Bulimus rufescens. Shell ovate-conic, perforate, glabrous, very 

 minutely striated, buff-whitish ; apex acute, brown ; peristome simple. 

 Length 1 inch. Jamaica (Gray, Ann. of Philos. (N. Ser.), ix, 1825, 

 p. 414). This name is prior, but may I think fairly be held insuf- 

 ficiently diagnostic.
