As Mr. DoNOVi^N has given a good figure of this obfcure 

 iTiell, and we think has with great propriety refered to Da 

 Gosta's S. glabej; we have adopted the name of ftibnlata. 

 This author defcribes it thus " It is an elegant fhell of a ta})er 

 form, thin, and femitranfparent ; when very perfect, of a 

 pale flefli-colour, fpirally wreathed with whitifh lines, and 

 others of an ochreous or brownifli hue : the llripes are not 

 uniformly difpofed alike in all fpecimens." 



Mr. Donovan received his from Weymouth. 



It is alfo a Scotijh fhell, Mr. Laskey having found it on 

 the fandy fliore near Dunbar, but confiders it very rare of 

 the fize defcribed ; but amongfl a box of minute fhells from 

 that coafl, we difcovered feveral much fmaller^ All thefe 

 fpecimens had invariably two yellowifh, or pale ferruginous 

 lines ; whereas the figure in the Britifh Shells exhibits no 

 lefs than fix lines on the body, and thefe appear to be of the 

 fame colour as ours. 



Shell with four ftrong, convex, volutions, and the apez Margarita. 

 moderately produced : colour white, with one faint rufous- 

 brown band on the upper part of the body whirl, following 

 the courfe of the wreaths, but is loft in the third volution : 

 aperture fub-lunated, fub-orbicular ; infide beautifully na- 

 cred : bafe very convex, and largely umbilicated. Diameter 

 one eighth of an inch or more.
