48 LAND AND FRESHWATER 
subovate angular above and below; peristome thin; columella 
with rather a sharp turn, truncate below. 
Size: major diam. 20°52; length 20°5 mm. 
The sculpture distinguishes this species from G. garoense, small 
var., in being much coarser. 
G. munipurense, n. sp., var. (3366 B.M.), Diyung Valley, Naga 
Hills, differs very slightly from the type. 
GLEssULA SUBHASTULA, Var. 
Locality. Munipur. 3 specimens. No. 3572 B.M. (Godwin- 
Austen). 
Shell elongately conoid; sculpture well marked, some irregular 
strie; colour sienna-brown ; spire high, sides somewhat flat, 
apex rather blunt (Plate CLXILI. figs. 138, 13a); suture impressed ; 
whorls 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. 18, 13 a). 
G. subhastula, n. sp. (No. 1591 B.M.), Lhota Naga Hills, 
four examples, similar to the type. 
GueEssULA OGLEI, n. sp. Type. (Plate CLXII. fig. 10.) 
Locality. Naga Hills. No. 820 B.M. (MZ. 7. Ogle). 
Shell elongate, oblong turreted; sculpture regular striation ; 
colour bright ochraceous; spire high, sides flatly convex; suture 
well impressed ; whorls 74, flatly convex ; aperture ovate; peristome 
well thickened on outer margin; columellar margin short and sharply 
concave. 
Size: major diam. 5:5; length 14:0 mm. 
Somewhat like G. oakest of the Abor Hills, but more slender and 
attenuate, apex finer, and aperture more oval. More elongate than 
G. crassilabris, and the sculpture is not so incised as in that species 
and its varieties. 
GLEssvLA 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.
