Bulinus opalinus, t. 38 /. 8. Sowerhy, Conch. Illust. Bulinus,/. 47. 
Shell oblong, pyramidal, smooth, glossy, hyaline and of milky whiteness; spire double the length of the 
aperture, of eight slightly convex whorls; suture distinct but not deep; aperture elliptical; lip white,

Bulinus scalariformis, t. 38./. 12. Brod. Zool. Proc. No. XVI. p. 31 . — Sowerhy, 
Conch. Illustr. Bulinus, f. 13. 
Inhab. Peru. 
The two varieties mentioned by Mr. Broderip, in the Zoological proceedings are represented. Some speci- 
mens are destitute of the longitudinal ribs ; such is the upper fig. 12 in t. 38, from Lima. 
Bulini Guadaloupensis VAR. ALBA, t. 38./. 13. 
Inhab. Brazil. 
At first I had mistaken the shell here figured for the Bui. candidus of Ziegler, but upon comparison I 
find it to be distinct from that, and that it agrees well with some colourless specimens of Bui. Guadaloupensis, 
a species which is extremely variable in its colouring and which is found in many of the West India islands 
as well as on several parts of the South American Main. 
Bulinus vittatus, t. 38./. 14. Brod. Zool. Proc. Number XVI. p. 31. — Sowerhy, 
Conch. Illustr. Bulinus, f. 6. and 6.* 
The specimen represented appears to be a young individual, it is marked on the drawing by Mr. Gray 
in pencil, B. Tacna.
