GUPPY : MOLLUSCA OF TRlNlDAD. 23! 



In the description of a new genus proposed by them for 

 certain West Indian Cjc/osfo/narecs {'] own. de Conch.,' 1888, 

 p. 234), MM. Crosse and Fischer repeat the error that Cyclo- 

 stomus seinidecussatus {— C. citrinns var.) is a native of Trinidad. 

 The only member of the Cyclostomace(z found in this island is 

 Cistula aripensis. 



In my last list I gave as doubtful three names. Of these 

 Aufotioe riparia is decided to be identica.] vfhh Atir/m/a pe/- 

 lucejis, but since my original discovery I have not seen another 

 specimen. Of Stenogyra coronata I never saw but one example, 

 and believe it must have been accidentally introduced. I 

 observe that the species is recorded from S. Lucia. Under 

 Pupa uvidifera I have stated my belief that P. aurifonnis is only 

 a form of that species. 



In Mr. Edgar A. Smith's paper (Report III. on the MoUusca 

 collected by Mr. Ramage in the Lesser Antilles, ' Ann. and 

 Mag. Nat. Hist.,' May, 1889, p. 400) Helix orhiadata Fer., and 

 Bulimus aidacostylus Pf., are attributed to Trinidad. These 

 statements are copied into the 'Journal de Conchyliologie' for 

 July, 1889, but without mention of the authorities on which 

 Smith based them. These species are not found in Trinidad, 

 and, so far as I know, they are confined to S. Lucia. 



In Reeve's Monograph of Helicina, IP. ri/gosa is ascribed 

 to Trinidad. It did not come from that island. Trinidad de 

 Cuba is probably more correct.

Hyalinia nitida var. albida Jeff, in Tipperary. — 



Amongst a small collection of Clonmel shells, kindly sent by 

 the Rev. A. H. Delap, was a specimen of the white variety of 

 this species. This form was apparently first differentiated by 

 Jeffreys in 1830 as Helix nitida var. /3 from an Irish specimen 

 supplied by Mr. Dillwyn. Westerlund makes a sub. -var. viri- 

 descens to embrace those specimens with a greenish tinge, and 

 this has also been recorded from Valentia, and was really the 

 precise form intended to be indicated by Jeffreys in 1830. — 

 J. W. Taylor, Aug. 20th, 1893.
