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

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

 depressed, thin, horny, becoming whitish beneath ; whorls 6, the 

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

 stome thickened within, and tlie columellar margin rather broadly 

 reflected at the umbilicus. 



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



ffab. 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 bluntly atigulate at 

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

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

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

 as in B. monticola.

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 Kudiu 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 G-hats. It is 

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

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