2 22 GUPPY : MOLLUSCA OF TRINIDAD. 



differ somewhat from the figure given by D'Orbigny, particularly 

 in respect of coloration. Hence I gave a new name to our 

 shell, but it is possible that they may all turn out to be only 

 one species. 



31. Veronicella occidentalis Guilding. 

 VeroniceUa IcBvis (Fer.) Guppy. 

 Crosse, 'Journ. de Conch.,' 1890, p. 48, No. 34. 



While admitting the force of the arguments urged by Crosse 

 so for as to alter the name Icevis (Fer.) to pccide?italis (Guilding), 

 the slug of that specific name having admittedly a range ex- 

 tending over the West Indies and Venezuela, I consider that 

 the name VeroniceUa is the preferable one for the genus. I do 

 not wish to occupy space by a long discussion on the point of 

 nomenclature, but it appears to me that what choice there is 

 is in favour of Veronicella. So far as my observations extend 

 the one species of slug found in the neighbouring Antilles is the 

 same as ours, and there is no necessity for the adoption of 

 Semper's w^iwe pnnctafissi/na.

These amphibious Auriculidee have the privilege of ap- 

 pearing in lists both of terrestrial aud of marine moUusca, 

 their geographical distribution following the latter, while their 

 zoological affinities appear to be with the land shells.
