it better, until the question is cleared up by the auatomy of the 

 aiiiinal, to include it in Cn/ptaustenia. 



Austenla saUus, Bs., var. ovata, G.-A., from Punkabari, Darjiling, 

 coll. W. T. B., tigurecl on Plate XXXVII. figs. 2, 2 a, is, I consider, 

 very likely to be Belicarion ovatum of Henry ¥. Blauford. 



Macroclilamys ovata, H. Blf., recorded by me in a " List of the 

 Dafla Hill Shells," J. A. S. B. 1876, p. 312, was a wrong deter- 

 mination ; it is quite distinct, and now stands as M. beata, Gr.-A. 

 Moll. Ind. ii. 1899, p. 156, PL CVIII. figs. 1, 1 a, 1 b.

" Distinguished from H. salius, Bens. sp. (with which it is 

 associated) by its larger siae, more depressed form and simple 

 peristome, not recurved at the columella. On the other hand, 

 it is smaller, more solid, and more globular than H. pilanospirci, 

 Bens. sp. From H. scutella, Bens, sp., and ff. bensoni, Pfr. sp., it 

 differs by its greater solidity, its highly polished surface, and 

 the less rapid increase of the last whorl. It is also smaller than 

 the former of these species." 



I have not been able to find the type shell in Mr. H. F. Blan- 

 ford's collection, which passed to his brother and then to the 

 Natural History Collection.
