658 Notes of some Land and Fresh Water Shells [July, 



white, flavescent green, or pale olive green, all being ornamented with 

 purplish or reddish brown flame shaped transverse bands, interrupted 

 and broken into dots by numerous longitudinal furrows, crossed and 

 wrinkled by the lines of growth ; in many specimens the whorls bor- 

 dering the sutures, and the summits of the tubercles are white, which 

 adds greatly to the beauty of the shell ; aperture oblique, subovate, 

 longer than broad ; operculum horny, and deep brown. 



This shell is an inhabitant also of our Indian rivers, and was dis- 

 covered by Mr. Benson, several years ago. As it was not found beyond 

 Beebee Nanee in the Bolan Pass, it can scarcely be called an Afghan 

 species, though it may serve perhaps to point out the western limits of 

 its geographical range.

1830, p. 22, species B. 



This common Indian species occurs plentifully at Dadur in Cutch 

 Gundava, and attains a size and beauty equal to any specimens from 

 the Gangetic Provinces. Leaving Dadur and entering the Bolan Pass 

 we again find it mixed up with the foregoing species at Bebee Nanee, 

 but generally of smaller size and less beautiful in the markings. Pro- 

 ceeding onwards we meet with it at Quettah in a clear stream, though 

 of still smaller size than before ; this last is that variety of the Indian 

 shell which has a well defined longitudinal reddish brown band along 

 the outside of the columellar or pillar lip. In a marshy and semi-stag- 

 nant piece of water at Quettah there is also another variety, large and 

 coarse in sculpture, without markings, and the apex of the spire and 

 epidermis eroded. 



As Beebee Nanee appears to be the limit to the range of M. elegans» 

 so Quettah would appear to be the limit of M. pyramis, as I found no 

 trace of it in the streams farther to the westward.

Shell devoid of apex, the spire being invariably much eroded ; gene, 

 ral appearance that of M. pyramis, but differs in being coarser, in 

 wanting the strong and prominent longitudinal furrows which charac- 

 terise that species, and which are observable throughout its length ; the 

 outer lip also lias a tendency to be more produced ; while the flame- 

 shaped streaks of colouring are narrower, closer, and less devious or 

 zigzag, often becoming bifid or pronged on the body whorl ; epidermis
