Subfamily Macrochlamtin^. 



Genus Macrochlamts. 



{Continued from Vol. IT. Part XL p. 272, 1910.) 



In tlie Kashmir Himalaya certain variation is apparent in species 

 of tlie subfamily Macrochlaiin/iuce. Novill noticed this in 1878, 

 when he placed cldoroplax, Bs., and Tcashmirensis, Nev., in llotula 

 as a subgenus of Nanina. Blanford later, when preparing for the 

 publication of the first molluscan volume of the ' J^'auua of British 

 India,' suggested Parvutella for flemingi, inhabiting the Murri 

 Hills, which Pfeilfer originally placed in Vitrina. I have since 

 found that ParvcUella extends to Samarkand. M. kashmirensis and 

 sonamurgensis are sufficiently distinct to be placed in a new sub- 

 genus I now describe. Other species of it will in all probability 

 occur away to the westward in the highlands of Buner, Swat, and 

 the Panjkora River, whoii those hills shall be collected in for land 

 mollusca. Nothing is known at present from that large extent of 

 country. 



Subgenus Uhadella, nov. 



Type, R. l-ashmirensis, G. Nevill. 



Sliell small, perforate, considerably depressed or lenticular, more 

 or less carinate. Sculpture plicately striate above, less so below, 

 smooth near the umbilicus or closely ribbed above, and beneath 

 much smoother. 



Animal with small right and left shell-lobes. Generative organs 

 like those of Macrochhtmi/s ; coiled csecum of penis large.

KhasieUa ? Jcashmirensis, Nevill. 



Nevill described this species in the ' Scientific Results of the 

 Second Yarkand Mission (Mollusca),' 1878, p. 16 (Plate, figs. 13- 

 15), placing it in the above subgenus. 



Original description: — "Sliell small, elo«ely resembling the pre- 

 ceding Nanina (Kotula) cldoroplax, from w^hich it can, however, be 

 easily distinguished by its smuller size, less de])ressed shape, much 

 more closely-wound whorls, higher spire, and less acute keel ; by 

 tlie more convex base, which does not possess the excavated depres- 

 sion round the umbilicus so characteristic of its ally ; the umbilicus
