220 GUPPY : MOLLUSCA OF TRINIDAD. 



25. Pupa eyriesi Drouet. 

 Drouet, 'Moll. Guy. frang.,' p. 71, pi. ii., f. 16—17, 

 Crosse, I.e., p. 44, No. 24. 



A very minute short and obtusely-cylindrical shell of 

 about five whorls, the last deeply impressed near the aperture, 

 the reflected outer lip being thus sinuate : apex very obtuse. 

 Height i| mill., diameter 1 mill. 



It is probable that this species described by Drouet from 

 French Guiana is more widely distributed than is thought, and 

 perhaps it is recorded under other names from other places. 

 The Guadelupe P. indigena (Ancey) may perhaps be the 

 same ; but the specimens I have received as F. eyriesi from that 

 island are more like F. pellucida, while the Trinidad shell 

 agrees fairly in the characters of the aperture with Drouet's 

 figure, and only differs in having a more obtuse apex. The 

 teeth of the aperture vary in number in different examples. 

 When they are all developed the figure is a good representation 

 of the aperture. 



26. Ennea bicolor Hutton. 

 Crosse, I.e., p. 37, No. 2. 



Chenu, 'Man. Conch./ vol. i., p. 444, f. 32S1. 



A cylindrical shell with a somewhat obtuse apex and an 

 aperture furnished with three teeth or plaits ; columella and 

 outer lip expanded and reflected. Length 7 mill., diameter 

 2 mill. 



On the occurrence of this shell in the West Indies see 

 Bland, 'Ann. Lye. Nat. Hist, New York,' vol. vi., p. 147. 



27. Streptaxis deformis Fer. 



Chenu. 'Man. Conch.,' vol. i., p. 451, f. 3362. 

 Crosse, I.e., p. 37, No. 3. 



A subtransparent whitish shell with a thickened outer lip 

 and a lamellar parietal plait. Length 6-|- mill., diameter 5 mill. 

 These are usual dimensions, but we have a variety of somewhat
