This species inhabits the neighbouring islands of St. Vin- 

 cent, Tobago, and Trinidad, and it extends along the northern 

 parts of South America from New Granada to i3razil. It is 

 stated by Bland t that it was introduced into Barbados from 

 St. Vincent by the liev. J. Parkinson.

I have compared the types of B. barhadensis with spe- 

 cimens of this species, and they appear to be inseparable. 

 Pfeiffer's term " solidiuscula " is somewhat misleading, for, 

 although one of the three specimens in Cuming's collection is 

 a little less delicate than usual, the other two are normally 

 thin. 



10. Bulimulus fraterculus, Ferussac. 



Bulimus fratemdus, Ferussac, Reeve, Conch. Icon. fig. 438 ; Pfeiffer,

Hab. Guadeloupe?, Porto Rico, Antigua, St. Christopher, 

 St. Kitts, St. John, St. Croix, St. Thomas, Trinidad ; Bar- 

 bados (^Bland). 



This species is closely allied to B. tenuissijnus, but is some- 

 what different in the proportional size of the whorls, the last 

 being smaller than that of the species referred to. 



11*. Bulimulus exilis (Gmelin). 



Bulimus ed'ilis, Reeve, Conch. Icon. figs. 292, 294 a, b (as yuadaloup- 

 ensis). 



This species occurs on several of the adjacent islands and 

 also on the mainland in Guiana. " It is very common 

 throughout the island, under stones, and clinging to the 

 trunks of trees, and the branches of shrubs in gardens."
