Truncatella barbadensis Pfeiffer. This is one of the species 

 pecuhar to Barbados and has been met with all over the island. 



Helicina substriata Gray. — St. Kitts, and the writer has also 

 received it from Barbuda. Found all over the island, some of the 

 shells being very prettily marked and coloured, a bright yellow variety 

 was met with in several places. 



H. barbadensis Pfeiffer. — Peculiar to Barbados. Found in 

 Porter's Wood and other localities, but not common. 



H. rugosa Pfeiffer. — Cuba, Hayti, St. Vincent. Found along with 

 H. barbadensis in Porter's Wood. It is a smaller sliell and can be 

 identified by tiie very strong diagonal striation. 



H. conoidea Pfeiffer. — Barbados (in coll. Cuming). The author 

 has not yet met with this species. 



Physa rivalis Maton & Rackett. — Brazil, Cuba, St. Vincent, 

 Trinidad, Grenada. In the swamps and pools in the island this was

 It has also been met with in the centre of the island in a fresh 

 water spring. 



P. ventrosa Montagu. — Mediterranean region, along the coast 

 of west and north-west Europe, and probably the Baltic. The only 

 two specimens found were secured in Porter's Wood. They had

 water species Planorbis cultratiis was found at the same time.

 Malvern Lodge gully, St. Michael's. 



Limnaea cubensis Pfeiffer, var. — Found in large quantities in 

 swampy field on Bryden's estate, St. Michael's. The identification of 

 this species was undertaken by Mr. Charles T. Simpson, of the Smith- 

 sonian Institution, Washington, who refers to it as follows : — " The
