48 LAND AND FRESHWATER 



subovate angular above and below ; peristome thin ; columella 

 with rather a sharp turn, truncate below. 



Size : major diam. 20'o2 ; length 20'5 mm. 



The sculpture distinguishes this species from G. garooise, small 

 var., in being much coarser. 



O. munipurense, a. sp., var. (3366 B.M.), Di3ung Yallej-, Naga 

 Hills, differs very slightly from the type. 



Glessula stjbhastula, var. 



Locality. Munipur. 3 specimens. No. 3572 B.M. {Godwin- 

 Avsten). 



Shell elongately conoid ; sculpture well marked, some irregular 

 strite; colour sienna-brown; spire high, sides somewhat flat, 

 apex rather blunt (Plate CLXIII. figs. 13, 13«) ; suture impressed ; 

 wliorls 8, sides flatly convex ; aperture narrow, almost straight 

 on the outer margin ; peristome a little thickened ; columellar 

 margin slightly convex. 



Size: major diam. 3-3 ; alt. axis 10-0 mm. 



Differs slightly from the Khasi Hill form in being less attenuate, 

 the sides of the spire being more convex above the larger body- 

 whorl, more particularly in the sharper apex, which is very 

 costulate throughout (Plate CLXIII. figs. 13, 13 a). 



G. subJiastula, n. sp. (No. 1591 B.M.), Lhota Naga Hills, 

 four examples, similar to the type. 



Glessttla oglei, n. sp. Type. (Plate CLXII. fig. 10.) 



Locality. Naga Hills. No. 820 B.M. {M. T. Ogle). 



Shell elongate, oblong turreted ; sculpture regular striation ; 

 colour bright ochraceous ; spire high, sides flatly convex ; suture 

 well impressed; whorls 7^, flatly convex ; aperture ovate; peristome 

 well thickened on outer margin; columellar margin short aud sharply 

 concave. 



Size : major diam. 5-5 ; length l-l'D mm. 



Somewhat like G. oakesi of the Abor Hills, but more slender and 

 attenuate, apex finer, and aperture more oval. More elongate than 

 G. crassilahris, aud the sculpture is not so incised as in that species 

 aud its varieties. 



Glbssula oglei, n. sp. (Plate CLXII. fig. 11.) 



Locality. Naga Hills. No. 3363 B.M. ( Godwin- Austen). 



Sculpture rather coarse striation, not incised ; whorls 7. 



Size: major diam. 6-5 ; alt. axis 14-25 mm. 



The figure of this species is somewhat more tumid than the 

 type, but found with it are two quite similar; they are not to be 

 separated.
