248 LA.NU AND FEESnWATEE 



This shell is not at all like M. subjecta, having a far more globose 

 body-whorl and smaller aperture, nor does it approach vesicida of 

 Mussoorie. I cannot match it with any species in my collection. 



Two specimens have been sent me from the Indian Museum, Cal- 

 cutta; they represent those recorded under IVo. 46 of il/. subjecta 

 of Nevill's Hand-list, p, 25, 8 Saharunpur. There is here a large 

 Botanical Garden, which was formed many years ago, and it is not 

 at all unlikely these shells were collected in it. It creates a doubt 

 as to whether they are indigenous or have been introduced with 

 plants from some part of the East. This species should therefore 

 be sought for again in the surrounding country between the 

 Jumna and Ganges. 



Shell smooth ; columellar margin oblique. 



Macbochlamys vesica, n. sp. (Plate CXVIII. figs. 2-2 c x 2-4.) 



Locality. Teria Ghat, foot of Khasi Hills {Godivin- Austen). — 

 Type, No. 494 B.M. Coll. 



Shell very narrowly perforate, the perforation partly hidden, 

 depressedly globose, rather flat at base ; sculpture none ; colour 

 pale burnt-sienna ; spire low, sides rather flat ; apex bluntly 

 rounded ; sutuni iinpressed ; whorls 5, the first 4 closely wound, 

 the last more tumid ; aperture rather narrowly lunate ; peristome 

 thin, oblique; columellar margin very oblique and slightly thickened 

 and shortly reflected near the perforation. 



Size : maj. diam. 14-25, min. 12-5 ; alt. axis 7*5 mm. 



This is the species which for some time was ascribed to 

 M. subjecta by Stoliczka and others, and is recorded by Nevill in his 

 Hand-list, p. 25, No. 4(5, 5 Teria Ghat ; I have seen these shells and 

 compared them with my types. Those catalogued from Borpani 

 and Dikrang, Dafla Hills, are also M. vesica ; those from the Naga 

 Hills I have not seen, they are probably the same species ; the 

 8 from Saharunpur are another species, more close to 21. subjecta, 

 and described above. 



The series of this species, taken at widely separated localities, 

 differs so much, that I have thought it desirable to give descriptions 

 of several of them. It is variation very apparent to the eye, but 

 not easy to define in words. 



Maceochlamys vesica, u. sp. (Plate CXVIII. figs. 3-3 r, and 

 another specimen fig. 3 cl.) 



Locality. Chatak, Sylhet District, Lower Bengal (Godwin- 

 Avsten).— 'No. 493 B.M. Coll. 



The specimen figured '3d. Shell of a bright glassy lustre, de- 

 pressedly globose, scarcely perforate ; sculpture, no striation visible; 

 colour pinkish brow n when dead ; spire depressed, apex rounded ; 

 suture impressed; whorls 6, convex; aperture semilunate; peri- 

 stome thin ; columellar margin slightly thickened, oblique. 



Size : maj. diam. 13'7, min. 12-7 ; alt. axis 8-5 mm.
