" Specimens of />'. prcvtermissus were first found by ourselves 

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

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

 first six varieties came thence ; No. 7, whicb 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.) 



liachisellus prcetermissus is allied to R. bem/alensis but iias a 

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

 variable as regards banding than any of the other Indian species 

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

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

 or less interrupted by transverse streaks, especially the upper 

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

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

 has in addition a broad pale reddish zone between the suture 

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

 three bands, 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 uubanded 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 bauds, three of which — interrupted — are 

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

 broad and eutire, 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 22x12-5 mm. and have the third and 

 fourth bands faint and interrupted. Two specimens, collected at 

 Bombay by A. H. Leitli, are labelled mavoriins, var. ; these I refer 

 to i>rcetermissus.
