766 ME, W. T. BLANFOBD OH SHELLS OF THE [Juiie 6, 



Amongst the specimens sent to me for examination by Col. Bed- 

 dome is a single shell from the Wjnaad which appears to be a still 

 larger form, measuring 8, 6, and 4 mm.

This, like some other South Indian Streptaxes, is a very variable 

 species. Even amongst specimens from the Kolamalais some shells 

 are much more depressed than others, the largest examined 

 measuring 11^, 85, and 5| mm. in its three diameters, whilst the 

 smallest measures 8|, 6^, and 4|. The single specimen from 

 Balur, iu the Kudur district of Mysore, measures 10, 7|, and Oj. 

 Then the palatal teeth vary in almost every individual examined : 

 the normal arrangement appears to be two in the right margin, one 

 of them opposite the end of the median parietal lamella, the other 

 ueai'er the angle, oue basal or distal, aud one columellar nearer to 

 the distal extremity of the aperture than to the proximal end. 

 Some specimens (as in fig. 8) have two columellar teeth ; in one shell 

 the basal and columellar teeth are wanting, but this is evidently 

 abnormal. Even in the escentricity of the last whorl, shown by 

 the extent to which the penultimate projects when viewed from 

 below, there is some variation. 



This species is distinguished from most of the South Indian 

 Streptaxes by its subcostulate striation, The species with similar 

 sculpture are S. pronus, which is smaller and very differently 

 shaped, and S. canaricus and S. subaeutus, with the penultimate 

 whorl keeled. 



A single specimen from Torna was obtained some 30 years ago 

 by Col. Evezard and has been in my possession ever since. It was 

 noticed in " Contributions to Indian Malacology, No. xii." ( J. A. S. B. 

 xlix. pt. 2, 1880, p. 205), as coming from the most northern locality 

 in Peninsular India from which a Streptaxis has been obtained. 

 Torna is a Mahratta hill-fort, near Sinhgarh, south-west of 

 Pooua. The Torna shell is large (length Hi, breadth 8|, height 

 6 mm.) aud somewhat weathered, with the whorls slightly sub 

 annulate below the suture and with traces of spiral sculpture on
