208 HELICIDjE. 



Pliocaihaica, frequently with translucent patches or dappled with 

 brown. Aperture more oblique than in Eucathaica, the reflexed 

 margin less thickened within, the tooth, characteristic of Cathaica, 

 but faintly indicated, generally only present in the smaller forms. 

 The last whorl shows an indication of an augulation at the upper 

 portion. Frequently two brown bands are present, which oc- 

 casionally are partly dissolved or interrupted. (Andreae.)

Original description : " Shell a little smaller than H. plectotropis^ 

 in many respects a good deal resembling it, but of much thinner 

 and more delicate texture; openly umbilicate, depressedly conoidal; 

 whorls five and a half, with excavated suture and without a raised 

 keel, in both of which respects it materially differs from the 

 preceding [ZT. plectotropis'], last whorls with a medium-sized keel, 

 base convex, above sculptured irregularly, with more or less strongly 

 developed ribs, beneath sculpture obsolete, almost smooth ; white, 

 irregularly mottled with pale horn colour, apex horn brown ; 

 aperture ovate, subangulate at periphery, almost as high as broad ; 

 peristome lightly reflexed, columella expanded.

" Unfortunately most are quite young shells, only one or two 

 being sufficiently full grown to show the reflexed outer lip. 

 Stoliczka describes the animal in his journal as * uniform greenish 

 dusky, no trace of a tail gland, the body very short, the posterior 

 part of the foot shorter than the anterior.' " (Nevill.)
