Blanford describes it as follows : — " Shell obtectly perforate or 

 subperforate, conoidly subglobose, smooth, polished, whitish horny ; 

 spire low conoid, suture impressed; whorls 5^, convex, the last 

 broader, rounded externally and beneath ; aperture subvertical, 

 roundly lunate, broader than high ; peristome thin, in one plane ; 

 columellar margin vertical above and expanded, almost closing the 

 perforation. 



"Major diam. lU, min. 10, height 7 mm. 

 ^ " Hab. Western Himalayas ; Almorah, Naini Tal ; Mussoorie ; 

 Kotgarh near Simla. 



" A smaller shell than M. vesicula, with a larger mouth and the 

 perforation nearly closed." 



Specimen collected by Dr. N. Annandale at Bhim Tal, Kumaon. 



Animal. In spirit very pale coloured with some fine motthng 

 near extremity of the foot. A small tongue-shaped right shell- 

 lobe and a very small left shell-lobe. The 'left dorsal lobe in two 

 parts distinctly separate. The generative organs (Plate CXXIX. 

 fig. 5a) are very minute; the' penis is only 1-54 mm. in total 

 length, yet the coiled coecum is very distinctly seen ; the amatorial 

 organ is 2-1 mm. in length. 



_ In the radula(fig. 5) the central tooth is tricuspid, theadmedians 

 bicuspid, the laterals evenly bicuspid, becoming small on the margin ; 

 the formula being: — 



35 . 2 . 10 . 1 . 10 . 2 . 35 

 or 47 . 1 . 47. 



This species has similar habits to those of Limax. Mr. Annan- 

 dale, who collected the specimen above described, writes : — 



" This morning I was interested to observe a small sn:iil hanging 

 vertically by a thread of slime about 15 feet long, and I notice 

 that one little species very common on leaves in this neighbourhood 

 frequently remains suspended in this way by a short thread 

 proceeding from the posterior extremity of the foot " 



Shell also from Bhim Tal figured (Plate CXXVIII. fig. 10). 



Size : maj. diam. 10-75, min. 9-25 ; alt. axis 5-5 mm. 



M. nuda', Pfr., vide Faun. Brit. Ind., Moll. (1908) p. 81, is 

 apparently the same as M. glauca. 



Macrochlamys kuluensis, Blf. (Plate CXXVIII. fig. 12 ; Plate 

 CXXIX. fig. 7, spermatophore.) 



Macrochlamys hiluensis, Blf. (Nevill, MS.) P. Z. S. 1904, ii. p. 442, 

 pi. 25. fig. 5. ' 1 ' 



In Faun. Brit. Ind., Moll. (1908) p. 81, it is thus described:— 

 " Shell openly perforate, subumbilicate, depressedly subglobose.
