shiny ; sculpture none ; colour pale sap-green ; spire depressedly 

 conoid; suture shallow; whorls 4, the last large and tumid, 

 rather rapidly increasing; aperture widely lunate, suhvertical ; 

 peristome very thin ; columellar margin very oblique, neither 

 thickened nor reflected.

This shell is extremely close to M. razamiensis of the Naga 

 Hills, some 150 miles further east ; placed side by side, the 

 difference of form in the more tumid shell and closer wound 

 whorls of razamiensis is at once apparent, vide PI. CVIII. 

 figs. 2-2 6. Only two specimens found. Animal not seen. 



Macrochlamys ? SPH^KICA, n. sp. (Plate CXXVI. figs. 6, 6a.) 



Locality. Nongsingriang Wood, N.W. Khasi (Godwin- Austen). 



Shell globularly conoid, imperforate, covered with a dark-coloured 

 membranaceous epidermis ; scul|)ture none; colour bleached, quite 

 an old shell; spire very low, apex rounded ; suture very shallow ; 

 whorls 4, rapidly increasing, the last very ample, flattened above ; 

 aperture roundly lunate, quite circular on the periphery, sub- 

 vertical ; peristome very thin ; columellar margin perpendicular, 



Size: maj. diam. 10, min. 8 ; alt. axis 4'8 mm. 



Only one specimen was obtained, its globular form distinguishes 

 it at once from another membranaceous shell living in the same 

 wood. In Mr. Q. K. Grude's collection, I have seen a shell from 

 Cherra Poonjee of a pale liver-colour, with bright shining surface, 

 which is of similar form to aphoirica- The spire is not normal; 

 there are the same number of whorls, but the second is extremely 

 narrow having been overgrown by the third, giving the spire a 

 very contracted appearance. 



Mackochlamts ? HEKBiA, n. sp. (Plate CXXIII. figs. 2, 2 a.) 



Locality. ISTaga Hills {Godivin- Austen). 



Shell depressedly globose, closely umbilicated, ratlier flat on base, 

 very thin and membranaceous ; sculpture none ; colour dull green ; 

 spire low, apex blunt ; snture moderately impressed ; whorls 5, 

 closely wound near apex, then increasing in size ; aperture broadly 

 lunate, suboblique : columellar margin suboblique, slightly thick- 

 ened, not reflected. 



Size, largest: maj. diam. 9-5, min. 8-5; alt. axis 4-0 mm.
