650 Notices of some Land and Fresh Water Shells [Jvly, 



Found at Candahar in April, crawling along the sides of damp ditches 

 in the fields ; not rare, though apparently local, and only comes out 

 about sunset. It is a true Parmacellus of Rang. 



2. — Vitrina baccata (Hutton). 



This very minute species was found under stones, along the bank 

 of a dry nullah or river bed, at a place called Melmandeh, between 

 the Kojuck Pass and Candahar. It appeared to be very scarce, as 

 after a lengthened search only three specimens were found, and of these 

 unfortunately the animals died before an opportunity occurred for ex- 

 amining them. 



Shell small, thin, fragile, diaphanous and pale ; whorls apparently 

 only one, or at all events the body whorl may be said to constitute the 

 whole shell ; aperture nearly circular, lips scarcely interrupted, slightly 

 thickened and partially reflected ; surface of the shell polished, finely 

 striated by minute lines of growth, and ornamented with longitudinal 

 bead-like lines or strings of minute bubbles, which can be seen only 

 under a strong lens. Upper side depressed, flattened ; under side round- 

 ed, ventricose. Length 1^ lines. 



3. — Helix Candaharica (Pfr.). 



Animal pale straw colour ; darkish or dusky on the tentacula ; foot 

 not protruding posteriorly beyond the shell, and rather tapering. 



Shell much depressed above, orbicular, slightly convex ; spire scarce- 

 ly exserted, whorls 5 ; colour fuscous or sandy white, ornamented above 

 with a broad longitudinal band of reddish or purplish brown ; often 

 breaking into dots where interrupted by the stria? of increase ; whorls 

 shining and obliquely striate ; aperture ovato -lunate, somewhat oblique ; 

 peristome acute, with a thickened rib within the aperture in mature 

 shells ; deeply and widely umbilicate, exposing the penultimate whorl 

 and extending nearly to the apex ; under side ornamented with narrow 

 dotted or interrupted longitudinal bands of reddish brown, varying 

 much in number from one to six ; diameter of largest specimen t 6 q of an 

 inch ; though the generality do not exceed half an inch. 



This is a very variable species in regard to colouring, some individuals 

 having the bands well denned, others having them faint and narrow, 

 and some wanting them altogether, in which case the shell is of a faint 

 fuscescent white with dark apex.
