" 7. Whorls obliquely and undulately striped with brown, one 

 stripe round the lower part of the last whorl. Suture near the 

 top purplish black ; apex black. 



" Specimens of B. prcetermissus were first found by ourselves 

 5 years ago in the tributary mehals of Cuttack, in Orissa ; and 

 were by us long considered as a variety of B. Bengalensis. The 

 first six varieties came thence ; JSTo. 7, which is rather more highly 

 coloured, occurs amongst the shells sent from S. India by 

 Mr. King, who found it on detached hills, N.E. of Conaniputty, 

 in the Salem district." ( W. T. and H. F. Blanford.} 



Rachisellus prcetermissus is allied to R. benyalensis but has a 

 narrower base and a more slender spire. It appears rather more 

 variable as regards banding than any of the other Indian species 

 of RachiseUus. Among a number in the Beddome collection, from 

 the Madura Hills, occur two shells which possess four bands, more 

 or less interrupted by transverse streaks, especially the upper 

 three, and a faint indication of a fifth band around the umbilicus. 

 Four others have only the fourth (sub-peripheral), while a fifth 

 has in addition a broad pale reddish zone between the suture 

 and the periphery, apparently the result of the fusion of the first 

 three bauds, and a coloured columella. One specimen is bandless. 

 All are subangulated at the periphery. Another batch in the 

 same collection, labelled S. India, contains two unhanded shells, 

 one of which is of a pale fuscous colour, becoming darker towards 

 the aperture, especially below the periphery. A third specimen 

 is ornamented with six bands, three of which interrupted are 

 supra-peripheral, aud three infra-peripheral, the fourth rather 

 broad and entire, dark chestnut, the fifth narrower, paler, and 

 interrupted, the sixth darker and broader, entire, and giving off 

 a paler fuscous zone reaching as far as the umbilicus. The 

 Theobald collection in the British Museum comprises two shells 

 from Orissa, which measure 22 x 12-5 mm. and have the third and 

 fourth bands faint and interrupted. Two specimens, collected at 

 Bombay by A. H. Leith, are labelled mavortius, var. ; these I refer 

 to prcetermissus.
