" Distinguished from the larger Khasia species, A. crassilahris, B., 

 by its peculiar sculpture, and by the formation of the whorls below 

 the suture." 



The specimen figured is from Hy. Blanford's collection N"o. 17, 

 O.iii.15, and measures 11-2.5 x o mm. There are two other 

 examples, and in another box (No. 243, 06.2.2 B.M.)are four others 

 all alike and from Darjiling. 



Mr. Gude, in ' Fauna British India, Mollusca,' ii. 1914, says : 

 " Some specimens in the Boddome collection from the Naga Hills, 

 composed of Oi whorls, measure 8 x 3'5 mm., and refers to another 

 shell also from the same locality, possessing only six whorls, with 

 rather conxex sides, measuring 6'5 x 3 mm. " I liave now seen 

 these (No. 76>! of my catalogue of the shells selected out of tho 

 B.'ddome collection). They are Glessiila jiroiviensis, mihi, and very 

 different in every way. The apex of one is given on Plate CLXIII. 

 tin. 4 ; also that of G. orobia from the Henry Blanford collection, 

 No. 17, fig. 8. 



Glessula orobia, Bs., var. major. (Plate CLXII. fig. 7.) 



llichila Peak, Sikhim. Type. (No. 556 BM.) 



Damsang, Sikhim. (No. 3336.) 



This is a much larger shell, yet has all the characters of the 

 Darjiling examples in its general form and increase of the whorls. 

 It is, however, a dark umber-brown, and in tliis respect is like 

 craasula from the same peak, which is a much smaller shell. 



Var. major measures : maj. diam. 5'2 ; length 130 mm.

The generative organs were seen complete and proved of great 

 interest. The appendage given off near the junction of the vas 

 deferens at head of the penis is small and hand-shaped ; it consists
