vesicida in his colieclion. It may have been made from the shells 

 named vesicula at Cambridge, or in the Natural History Museum.] 



Major diam. 14, min. 12^, height 7 mm. 



Hab. Near Simla and Mussooree up to about 10,000 feet 

 (Huti07i) • I have also specimens from Murree. According to 

 Benson, various shells from the plains of India (Eiijmahal &c.) 

 belong to this form, and it was upon these specimens that his 

 description of 1852 was founded; but the typical form described 

 in 1838 was Himalayan and apparently fi'om Simla. Hutton 

 also referred to Helix vesicula shells found by him between Mhow 

 and Neemuch. These forms from the lowlands of Northern India 

 require recomparison ^ith the Himalayan type. The JWinina 

 (Maerochlami/s) vesicula of Nevill's Hand-list, i, p. 25, from Eaj- 

 mahal and Pareshnath, is probably, as suggested, 31. lecythis. 



M. vesicula is distinguished from M. suhjecta (p. 98) by its lower 

 spire, smaller last whorl, and less broad aperture, and generally 

 by higher lustre and paler colour. 



[It is possible vesicula of 1838 was M. glauca : only the collection 

 of a good series of shells of this type from the Simla and Mussoorie 

 Hills at different elevations can settle this point *.]

Shell obtectly perforate or subperforate, conoidly subglobose, 

 smooth, polished, whitish horny ; spire low conoid, suture im- 

 pressed ; Avhorls 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.

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

 perforatioiT nearly closed. 



[Specimen from Bliim Tal (N. Annandale). — Shell : major diam. 

 8 mm. Animal : very pale-coloured in spirit, ^ith some fine 

 mottling near the extremity of the foot. A small tongue-shaped 

 I'ight shell-lobe and very small left shell-lobe. The penis, which 

 is only 1*54 mm. in length, shows the coiled caecum very distinctly. 

 The radula is as usual ; the laterals evenly bicuspid, tlie last 3 or 4 

 on the margin witli a pectinate edge. 



Formula : 35 . 2 . 10 . 1 . 10 . 2 . 35. 



The species has similar habits to those of Limcuv. 



Mr. Annandale, of the Indian Museum, Calcutta, writing to me 

 from Bhim Tal, describes seeing one hanging by a thread of slime, 

 about 15 feet long, proceeding from the posterior extremity of the 

 foot.]
