(4) the secondary microscopic sculpture of S. grandis, resembling a 

 woven fabric. 



This may be the form which C. B. Adams mentions (Contrib. to 

 Conch., p. 173) as a large form of Helix epistylium, but it is not the 

 species so named by M tiller. Thirty specimens were taken. 



Probably C. B. Adams' Helix epistylium var. minor from West- 

 moreland (Contrib. to Conch., p. 173) will prove to be a distinct 

 species which will be called Sagda minor (C. B. Ad.). 



The var. delaminata of the same author (t. c, p. 174) from Easington 

 in the district of St. Davids is perhaps another distinct species, but 

 it has been very inadequately described. 

 Sagda spei n. sp. Fig. 9. 



The shell is of moderate size, solid, elevated, the height about 85 

 per cent, of the diameter, white under a thin pale brown-tinted cuticle; 

 quite glossy. The spire is broadly dome-shaped above. Whorls 

 about 8, moderately convex, the first \\ nearly smooth, the rest 

 sculptured with fine, slightly curved, retractive striae, which in large 

 specimens are usually weaker on the last whorl. Under a strong lens 

 very feeble traces of granulation are barely perceptible in places 

 between the stria 1 on the last whorl. The last whorl in a front view is 

 more than twice the height of the preceding whorl. It is convex 

 beneath and moderately excaved in the center. The aperture is 

 lunate. The basal lamella is about a half whorl long, well developed, 

 and revolves at the point of greatest convexity of the base. The 

 columellar lamella though distinct is very small.

This is a rather common snail eastward from Kingston. It differs 

 from S. jayana (C. B. Ad.) by the rudimentary columellar lamella and 

 by having the basal lamella situated further inward from the periphery. 

 In the structure of the lamella? it resembles S. grandis P. and B., from 

 which it differs by the greater height of the last whorl, the totally 

 distinct secondary sculpture, and the smaller apical whorl. 8. con- 

 nectens has the basal lamella more peripherally situated, and the spire 

 is much lower. S. alveare (Pfr.) has a more conic spire and lower 

 last whorl, but in the collection of the Academy numerous lots of this 

 species were so labelled. 



Sagda epistyloides Fer. is, according to the original figures, a shell 

 of about the size of S. spei; but it is represented as far more
