Size : major diameter 70, alt. axis i6'5 mm. 



Two specimens of this species, though rather smaller in size, 

 and not fully grown, were sent to me from Brahmakund by Mr. 

 M. Ogle, No. 3578 B.M. coll. The largest measures 11X5 ^^^ 

 The species was received alive in 1913, from Captain Oakes with 

 other species and dissected. 



Animal of Gkssula oakesi from Rotung (Oakes). The sole 

 of the foot is crossed by coarse ridges, there is a very distinct 

 peripodial margin (text-fig. 8 A). The genitalia (figs. 8 B, C, D) 

 was fairly well seen in one specimen but more material was sadly 

 wanted. The hermaphrodite duct is conspicuous from its size and 

 close convolution, bound closely together at its junction with the 

 albumen gland. The penis is very short with a short stout flagel- 

 lum terminating in three blunt knots, it thus differs from what 

 I have been able to see in other species. The vas deferens is given 

 off from near the head of the penis, the spermatheca was not seen.

Referring to the form of the flagellum I take the opportunity 

 of giving here (text-fig. 9), in anticipation of a lengthy contribu- 

 tion to the Mollusca of India on the Glessulae of the North-East 

 Frontier and Burma, a figure of the generative organs (fig. 9 C) 

 of Gkssula ochracea, G.-A., (a new species) from vSikhim in which 

 the penis is of the form of G. orophila as figured by Prof. C. 

 Semper {Reis, Philippinen) , the flagellum is much flattened with a 

 serrated edge on one side, indicative of the form of the spermato- 

 phore. 



This species (G. oakesi) is the same as the one recorded from Ro- 

 tung as G. botellus, Bs., of Southern India by Mr. H. B. Preston in 

 the " Records of the Indian Museum,'" Vol. VIII, Nov. 1915, p. 539 ; 

 it is a bare record, in any case remarkable as regards range. As I 

 had not noticed this South Indian species among the large series 

 sent me from the Abor Hills, I was anxious to see the shells which
