this species shells from Arakan, the Assam Hills, and near 

 Darjiling, but the identification requires further comparison. 



[Vide p. 35, Nevill's 'Hand-list': 



Only the shells from Phiethan belong to this species. 



I have gone through most of the shells referred to petasus from 

 localities in the Assam Hills and Darjiling, sent home to me by 

 Mr. G. Nevill ; they all belong to different species ; those recorded 

 from Toruputu, Borpani, Tanir Peak, and Dikrang are M. uda, 

 Godwin-Austen. 



Same page, " Var. (? distinct species) " : 



From places in the Dafla Hills belong to a form yet to be 

 described. 



Same page, " Yar. (? distinct species) " : 



12 Arakan are subpctasus, Godwin-Austen.

" Shell obtectly perforate, orbiculately depressed, scarcely 

 striated, smooth, polished, horny, subdiaphanous ; spire somewhat 

 convex, flattish, apex slightly raised ; suture faintly impressed, 

 submarginate; whorls 6, very slightly convex, slowly increasing, the 

 last finally broader ; aperture obli.que, broadly lunate ; peristome 

 briefly lying open (very slightly expanded), thickened and white 

 inside, broader below, upper margin prominent and much arcuate ; 

 basal margin arcuately bisinuate, columellar very short, slightly 

 reflected above, its border narrowly callous." (Bs., Latin.)
