it when on a river journey from Calcutta upwards near Soti Durga 

 and Eajmahal. McAndrew, probably in affixing the new labels 

 to Benson's shells, when they were transferred to slabs, repeated 

 and perpetuated the error in Pfeiffer's Monograph, vol. iii. p. 47, 

 viz. " Himalaya Mountains." 



Benson says : " Mantle of the animal has a long tentacula-like 

 process which lubricates the surface of the shell to the apex." 



At page 212 of J. A, S. B. vol. vii. (1838), three very distinct 

 species are brought together under the title of veslcula ; and 

 Hutton, under the impression they were identical, calls attention 

 to the very wide range of this species both in area and elevation. 



1st. Species from Neemuch and Who\v=IIeli.v No. 29, J. A. S. B. 

 vol, iii. (1834) p. 521, described but not named; mantle processes not 

 present. It would be very interesting to see what this is. 



2nd. From N.W. Himalaya, ascending to 10,500 ft. above the 

 sea, in profusion along the verge of the Hills at Mansir Debi and 

 up to Hattu Peak ; climbing on plants. Very probably M. glauca 

 or iu(da, if separable. 



3rd. Type described by Benson from Eajmahal, on Ganges, 

 casually referred to in J. A. S. B. vol. v. (1836) p. 357, from 

 Patargatha and Berharapur; ?ias extensile tentacular processes of 

 mantle. This must be 31. subjecia.

'■^ Hah. Near Simla and Mussoorie up to about 10,000 feet 

 {Hutton) ; I have also specimens from Murree. According to 

 Benson, various shells from the plains of India (Eajmahal <^'^^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 from Simla. Hutton 

 also referred to Helix vesicula shells found by him between Mhovv 

 and Neemuch. These forms from the lowlands of Northern India 

 require recomparison with the Himalayan type. The Nanina 

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

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



"if. vesicula is distinguished from M. suhjecta by its lower spire, 

 smaller last whorl, and less broad aperture, and generally by higher 

 lustre and paler colour."
