MOLLUSCA OF I>"D1A. 261 



Maceochlamys ? STRIATA, u. sp. (Plate CXXVI. fig, 10.) 



Locality. Silcuri, Cachar ( Wood-Mason). 



Shell subperforate, globose ; sculpture none, smooth, polished, 

 with regular lines of growth, showing alternately pale and dark 

 coloured ; colour rich uiuber-browu ; spire low, apex flatly 

 rounded ; suture shallow ; whorls 4, rapidly increasing, the last 

 expanded, rounded on periphery ; aperture widely lunate ; peri- 

 stome thin, not thickened at all at the columellar margin. 



Size: maj. diam. 12-25, min. 11*0; alt. axis 5'5 mm. 



Two specimens were found. 



Macrochlamts ? JAPVOENSis, u. sp. (Plate CXXVI. fig. 5.) 



Locality. Japvo Peak, Anghami Naga Hills, 10,000 ft. {G.-A.). 



Shell scarcely perforate, depressedly globose, base rather flat, 

 thin and membranaceous ; sculpture none, polished, streaked 

 transversely, particularly below, with lines of growth ; colour 

 olivaceous green ; spire moderately elevated, apex blunt ; suture 

 very shallow ; whorls 5, the last well-rounded on the periphery, 

 rather rapidly increasing ; aperture semi-lunate ; peristome 

 thickened ; columellar margin suboblique, not reflected at all. 



Size : maj. diam. 10*25 ; alt. axis 0"-± mm. 



Of this very interesting species I only obtained two specimens. 

 From the thickened peristome, with feeble columella, and its 

 transparent membranaceous shell, it might belong to the genus 

 Cryptaustenia, but as the animal is unknown I place it in 

 Macrochlamys. 



Mackochlamys ? NEMOTHAENSis, n. sp. (Plate CXXVI. fig. 7.) 



Locality. Nemotha Peak, Trigonometrical Station near Silchar, 

 Cachar {J. Wood-Mason). 



Shell globosely turbinate, thin, imperforate ; sculpture none, 

 surface shining ; colour a rich ochre with a greenish tinge ; spire 

 subpyramidal, apex rather pointed ; suture impressed ; whorls 5, 

 regularly increasing ; aperture lunate, as broad as high, sub- 

 vertical ; peristome thin ; columellar margin nearly vertical, then 

 becoming oblique, neither thickened nor reflected. 



Size : maj. diam. 10-75, min. 10-0 ; alt. axis 5"5 mm. 



There are numerous examples of this shell, provisionally named 

 M. sejjosiia. Bs., in Calcutta ; it caunot, however, be that species 

 which is from Darjiling and has 3 whorls only according to 

 Benson's description. It approaches M. razamiensis, G.-A., but 

 apex is not the same. It may possibly turn out to be Nanina 

 (Medyla) salmonea, Ancey, Le ISTat. ii. p. 119 (1882), from its 

 coloration, number of whorls, and general form. 



Macrochlamys? saltus, n. sp. (Plate CXXA^. figs. 2, 2a.) 



Locality. Moyong, N."W. Khasi Hills {Godwin- Austen). 



Shell globosely conoid, imperforate, very thin, transparent,
