652 Notices of some Land and Fresh Water Shells [July, 



This is likewise very numerous at Candahar, in gardens and fields, 

 adhering by a thin viscous plate to the stalks of plants ; it occurs also 

 abundantly among dead leaves beneath rose bushes, and at the roots of 

 the garden Iris and other plants ; sometimes buried in holes in the 

 earth. 



It appears to be closely allied to the three British shells, H. Can- 

 tiana (Montagu), H. Carthusiana (Gray), and H. Rufescens (Penn), 

 more especially to the latter, which it strongly resembles in colouring, 

 the angularity of the periphery and the blotches of darker colour seen 

 through the shell when the animal is living. In size perhaps it comes 

 nearest the former, as well as in general appearance, but it is less glo- 

 bose in the spire, and the peristome is more reflected. 

 5. — Succinea putris, (Gray.) 



There is really nothing to distinguish the Afghan from the Euro- 

 pean species ; the colour, number of whorls, size and shape appear to 

 be quite the same. The animal likewise seems to be in all respects the 

 same. The eyes are situated at the extremity of the superior ten- 

 tacula, which are cylindrical and buttoned ; the second pair diminutive 

 and scarcely apparent ; the whole animal is mottled minutely with 

 grey, and several fine grey lines extend backwards from the upper part 

 of the head. It is very common in garden drains, and in marsh lands 

 along the course of the river Helmund at Girishk. 

 6. — Succinea Pfeiferi (Rossm.). 



This is apparently another European species, closely allied to, and 

 by some supposed to be only a variety of the foregoing. It has a much 

 shorter spire than the other and the aperture is more elongate. 



It occurs plentifully in garden drains at Candahar, but did not ap- 

 pear to mix with the foregoing, and I should be much inclined to re- 

 gard them as distinct species. 

 7. — Pupa lapidaria (Hutton). 



Animal dusky. 



Shell composed of 7 cylindrical volutions, exclusive of apex ; the 

 three first whorls rapidly decreasing and producing an obtuse spire ; 

 the other whorls nearly equal ; colour brown ; finely wrinkled with ob- 

 lique striae of growth ; aperture ovato-quadrate ; lips subreflected, 

 polished and white within ; sub-umbilicate ; furnished with eight teeth, 

 two on the pillar within, four on the outer lip within, all of which are
