full-grown) ; Mexico, without nearer indication of locality (Uhde °).

chrast ¥ 1),

Antigua, Martinique, Barbados, Trinidad. 
Also introduced on the mainland of North America at Mobile in Alabama ® 1°; and 
on that of South America at Maracaibo (Brown). 
Probably in many places imported with cultivated plants, as exemplified by its 
occurrence on flower-pots 12. The record of it from Cochin China, on the coast of the 
Indian Sea °, is therefore not so very remarkable. 
Opeas rarum (Miller), form B, Strebel, loc. cit. p. 103, t. 7. fig. 0, from Mirador, 
East Mexico, is perhaps founded on young specimens of O. subula. 
2. Opeas bocourtianum. 
Stenogyra bocourtiana, Crosse & Fisch. Journ. de Conch. xvii. p. 424 (1869) ’. 
Bulimus bocourtianus, Pfr. Monogr. Helic. Vivent. viii. p. 136°.
