Bulimus sisalensis, Morelet, Test. Noviss. i. p. 9 (1849) ; ii. p. 27 (menkei ?) *., 
Bulimus venosus, Reeve, Conch. Icon. v., Bulimus, t. 45. fig. 285 7”. 
Bulimus virgulatus (Férussac), Leidy, in Binney’s Terr. air-breath. Moll. of N. Am. i. p. 259, t. 15. 
figg. 7, 8 (anatomy) (1851) *; Binney, op. cit. i. p. 278, t. 587°. 
Hab. Norta America: Eastern Florida (Say 17); Key West &c. 4&7, 
Yuoatan: Sisal, on sandy ground (Morelet > 1° 16). 
Cotompra: Santa Marta, Magdalena, and Bambo Bay 4 ®7. 
VENEZUELA: Maracaibo and Puerto Cabello (Swift4+®"); Angostura, on the borders 
of the R. Orinoco (§~1° 14). 
I have seen no specimen from Guatemala, but Morelet’s description © agrees so well 
with my Venezuelan examples, and with Binney’s figures of Florida ones, that I cannot 
distinguish the Yucatan shell even as a variety. As it is not known from E. Mexico, 
it cannot be said to be distributed generally along the shores of the Caribbean Sea. 
48. Otostomus heterogeneus.

v. p. 92°. 
Hab. W. Mexico: Tepic, State of Jalisco (Hége). 
E. Mexico: Mirador, Palo Gacho, on the road from Vera Cruz to Jalapa, and 
Rinconada near the same place (Strebel+); Vera Cruz (Berendt 1°). 
This species approaches 0. livescens, as Strebel has already stated *, and O. discrepans. 
From 0. livescens it differs in the somewhat more convex whorls, the less tapering
