height 13 J inra.), but I have a shell, probably from Kashmir, 

 measuring 45 mm. across. On the other hand, a small variety 

 from Chamba, barely adult, measures 23|x20xllJ mm. 



Hal>. Range south of Kashmir; Uri (Stoliczlca) ; Chamba State, 

 8000'.

This is a smaller shell than B. monticola, finely and flexuously 

 striated, decussated with very fine and close spiral lines. It i& 

 depressed, thin, horny, becoming whitish beneath ; whor]s 6, the 

 last rounded at the periphery, flatly convex beneath, the peri- 

 stome thickened within, and the columellar margin rather broadlv 

 reflected at the umbilicus. 



Major diam. 26, min. 23, height 12 mm. 



Hab. Tawi Valley, between Chaneni and Udampur, Kashmir. 



This is, perhaps, as Theobald has suggested, a small variety of 

 B. monticola, with few or no varices. Under the microscope 

 traces of oblique decussating raised lines on the epidermis can be 

 made out.

Shell subobtectly perforate, conoidly depressed, yellowish brown, 

 dull above, polished below, rugately striated, finely decussated 

 with close impressed spiral lines throughout ; spire low, conoidal ; 

 whorls 7, flat, scarcely convex above, the last bluntlv angulate at 

 the periphery, convex beneath ; aperture slightly oblique, sub- 

 angulately lunate ; peristome thin, with the usual internal callosity, 

 which shows through the shell ; former lips at irregular intervals, 

 as in B. monticola. 



Major diam. 27|, min. 23|, height 15 mm. 



Hab. Narkauda, E.N.E. of Simla; Kulu. 



Distinguished from B. monticola by smaller size, flatter whorls, 

 angulate periphery, different sculpture, and less oblique mouth. 

 A depressed form of B. theobaldiana occurs on the Chor, S.E. of 

 Simla. A specimen in Col. Beddome's possession, with 6 whorls, 

 measures major diam. 19, axis 8| mm. 



The locality Kudin quoted by Kobelt for his Nanina theobaldiana 

 is a mistake for Kulu. This and the two preceding species may 

 be varieties of B. monticola. 



A single specimen of a shell, apparently belonging to Bensonia, 

 was obtained by Col. Beddome in the South Canara Grhats. It is 

 doubtful if the single example obtained is adult, and without a 

 knowledge of the animal it would be unsafe to decide as to its
