 merous microscopic striae : spire with the outlines nearly rec- 

 tilinear : apex small : whorls eight or nine, moderately convex, 

 with a well impressed suture : aperture very thin and sharp : 

 columella straight. The whorls are proportionally shorter, 

 and the aperture is wider than in B. subula, Pfr., the revolu- 

 tion of the whorls being much less oblique. It nearly resem- 

 bles B. octonoides. 



Mean divergence about 18°; length ,42 inch ; breadth .12 

 inch ; length of aperture .12 inch. Inhabits gardens in King- 

 ston.

Helix Ckittyana, var. bicolor, is distinguished by a white 

 lip, and by having the whole lower surface, except the whitish 

 zone at the periphery, of a blackish brown. 



A series of specimens connects H. cava with H. amabilis 

 so closely, that the latter cannot be entitled to rank as more 

 than a variety. Some which have the color of H. cara, and a 

 well elevated spire, but otherwise resemble H. amabilis, may 

 be called var. iMEDiA. 



Helix Swainsoniana. Shell depressed, conic, subplanu- 

 late beneath ; with a moderately sharpened periphery, on both 

 No. 9—3.
