which appear nearer together and more in front than in Elseya lati- 

 sternum ; but as yet I do not know the upper surface of the head. 



Descriptions of new Land and Freshwater Shells from the 

 Khasi, North Cachar, and Naga Hills, N.E. Bengal. 

 By Major H. H. Godwin-Austen, F.R.G.S., F.Z.S., 

 &c, Deputy Superintendent, Topographical Survey of 



India. 



[Received March 18, 1872.] 

 (Plate XXX.) 



1. Melanoides spinata, sp. nov. (Plate XXX. fig. 1, 1 a, 

 operculum.) 



Shell angularly turreted ; colour olive-green ; spire acute, rather 

 rapidly decreasing in diameter ; apex eroded ; suture marked by a 

 distinct cord continuous with that on the lower angle of the last 

 whorl ; whorls 5-6 (there would be 8 if perfect), very convex and 

 flattened on the periphery, with strong tubercles arranged in two 

 parallel longitudinal rows, the spines being rather longer on the 

 upper ; aperture ovate, vertical, well channelled at the base, a thin 

 milky callus on the columellar margin, within pale grey with two 

 or more bands of brown coinciding with the rows of spines and the 

 corded surface of the outer base. 



Operculum paucispiral, nucleus subcentral. 



Animal 1*4 in. long; foot round and large, not angular in front; 

 colour grey, mottled with ochre ; body also grey, the ochre markings 

 showing as streaks ; tentacles very short, 0*4 inch. 



Length 2-20 ; diam. T15 ; apert. alt. 0*95, apert. lat. 0-60 inch. 



Hab. Kopili river, North Cachar hills, a tributary of the Brahma- 

 putra. 



Proportion of aperture to body-whorl - 95 to 1'35, or 2 to 3. 



I find this shell exceedingly abundant in the deep still pools of 

 the Kopili river, associated with a very large variety of Pal. ste- 

 phanas, Bs. 



2. Melanoides hanle\i, sp. nov. (Plate XXX. fig. 2.) 



Shell turreted, colour rich dark chestnut-brown ; spire rather 

 acuminate, rapidly decreasing ; apex eroded ; suture impressed but 

 slightly, but strongly marked ; whorls 5 (without the apical), flat, 

 sharply angular above with a single row of well-defined small tuber- 

 cles on the angular margin ; body-whorl large, well rounded below, 

 distinctly corded at base near the columellar margin ; aperture 

 vertical, ovate, very slightly effused at base ; within pale grey, with 

 three or more red-brown bands. 



Length 1*8; diam. 09.5 ; apert. alt. 0-/0, apert. lat. 0'50 inch. 



Hab. Diyung river, North Cachar hills.
