being finely crenulate. The Beddome collection comprises two 

 specimens from North Cachar, which were labelled monticola, but 

 which without hesitation I refer to asaluensis. One of these 

 is composed of twelve whorls and measures 24x4 mm., while the 

 other, which is a trifle more ventricose, has only eleven whorls, 

 and attains a length of but 21 mm., although its diameter reaches 

 4 mm. The Theobald collection, on the other hand, was found 

 to contain a shell labelled " bacillum, Theobald (non Benson)" 

 from the Khasi Hills, which also pertains to the present species. 

 It has twelve whorls and is a trifle more ventricose than the type, 

 for although its length is 22 mm., its diameter attains 4'75 mm.

" Out of a collection of 32 European Clausilice I find none with 

 a similar obliquity of mouth, from which character I have named 

 the species. The outer lip projects beyond the plane of the 

 aperture. The crenulations of the sutures differ altogether from 

 the papillary appearance which is common to several species, such 

 as papillaris, alboguttata, etc., and they are not elongated as in 

 C. nitida." (Benson.) 



Nevill (Hand List, i, p. 184), mentions but does not describe a 

 var. striatacostata collected by Lt.-Col. G-od win- Austen at Teria 

 Ghat, while Stoliczka states that " a white solid variety occurs on 

 the Khasi Hills ; in form it tolerably agrees with Blanford's 

 fig. 6 b, plate 9 ; some specimens are, however, still a little 

 thicker, and the transverse costulation on all the whorls is very 

 distinct, while the crenulation along the suture is generally not 

 so coarse as in typical loxostoma, though evidently stronger than
