Survey of India. 



(Received Sept. ;— Eead Nov. 4th, 1874.) 

 (With Plate I.) 



The following shells were obtained in the above hills between the years 

 1868 and 1873, when I was employed in the survey of that tract of country ; 

 the work afforded opportunities of visiting almost every part and of bring- 

 ing together a very large collection of the land and freshwater shells, a 

 complete list of which I hope some day to draw up. 



Helix dellbrata, Bs., var. easctata, Plate I, Fig. 1. 



Shell openly umbilicated, depressedly globose, rather solid, pale ochra- 

 ceous epidermis ; spire slightly raised, in some specimens quite fiat, very 

 prettily striped with brown concentric bands, one or two of which are 

 broader and more pronounced than the rest, especially on the base of shell ; 

 some specimens are ornamented with a single band only, last whorl 

 expanding towards aperture and slightly descending ; aperture sub-oblique, 

 circular, peristome thick, white, and reflected. 



Major diam. 0-82, minor 0-67, alt. 0.38 in. 



Sab. — On the high open grassy country of the West Khasi Hills. 



True delibrata, Bs. unhanded, with flat spire, and a larger shell, is 

 also found in the Khasi Hills.
