MOLLUSCA OF IXDIA. 203 



rather deep ; whorls 3k, the last very tumid and rounded on the 

 periphery ; aperture broadly lunate, oblique ; peristome thin ; 

 columellar margin perpendicular, not thickened, and scarcely 

 reflected. 



Size : m;ij. diam. 7*5, min. 6-75; alt. axis 8"0 mm. 



Only one specimen obtained. The Peak is covered with the 

 densest forest. 



Macrochlamys? pROPiiN-QUA, n. sp. (Plate CXXIII. figs. 3, 3a.) 



Locnlity. Komamedza, Naga Hills (Go'hvi n-Atisfen). 



Shell imperforate, globosely pyramidal, thin, very transparent, 

 membranaceous; sculpture hea,ut\i' ally, Jineh/ and regularly striate 

 lonyitadinallii, crossed with regular furrows of growth ; colour 

 very pale straw; spire moderately high, apex rounded; suture 

 shallow; whorls 4^, rather rapidly increasing; aperture semi- 

 lunate; columellar margin oblique, not thickened. 



Size : maj. diam. fi-5 ; alt. axis 3'2 mm. 



Only one specimen found, but it is very distiuct from other 

 species of this group known to me. 



Macrochlamts ? qu.5:sita, n. sp. Type. (Plate CXIX. figs. 12, 

 12 a, 12 h.) No. 240 B.M. Coll. 



Localitif. Burrail E-ange, Naga Hills, Assam {Godwin- Austen). 



Shell depressedly globose, very narrowly perforate: sculpture 

 none, dull surface ; colour pale ochraceous ; spire low ; suture 

 adpressed ; whorls 4|, closely woinid at apex, increasing rather 

 rapidly ; aperture lunate, descending slightly ; peristome thin ; 

 columellar margin suboblique, very slightly reflected. 



Size: maj. diam. 11'5, min. 10*5 ; alt. axis 5 mm. 



This species recalls M. moyongensis, but the form is more 

 globose and the columellar margin more oblique. It is represented 

 by four specimens. 



Macrochlamys beata, G.-A. (Plate CXXY. figs. 6-6 c.) 



Moll. Ind. vol. ii. p. 156, pi. cviii. figs. 1-1 b (shell). 

 Faun. Brit. Ind., Moll. p. 107. 



Shell with a very flat rounded apex was figured on Plate CVIII. 



I now give figure of one with a higher spire, also of the animal 

 (figs. 6 h, 6 r) which was soaked out and was in a very good state of 

 preservation. It is very dark in colour, the sole of the foot paler. 

 The lobe above mucous pore small. The right shell -lobe is tri- 

 angular, the base resting on the right dorsal lobe from the upper 

 inner angle of the aperture downwards. The left shell-lobe is long 

 and oblong in shape. Generative organs not preserved.
