58 LAND AND FRESHWATER 
large ; suture well impressed ; whorls 9, sides nearly flat; aperture 
small, ovate; columellar margin very convex. 
Size: maj. diam. 8°90; length 30°25 mm. 
This species was also found on the Mekong River, paler in 
colour, with an ashy tint. No. 3748 B.M. 
GLESSULA WOODTHORPEI, n. sp. (Plate CLXII. fig. 19.) 
Locality. Shan States. Nine specimens (Lt.-Col. R. Woodthorpe). 
Type. No. 1628 B.M. 
Shell oblong conoid, shiny, very smooth; sculpture: distant, 
rather coarse indistinct irregular strie; colour olivaceous; spire 
elongately conic, apex blunt; suture well impressed; whorls 7, 
gradually increasing, body-whorl to length 100: 55°6; aperture 
ovate, vertical; peristome outer tip thickened; columellar margin 
slightly concave, short, strong, truncate. 
Size: maj. diam. 5°75; length 13°5 mm. 
This shell has a likeness to G. crassilabris, but the aperture is 
smaller in proportion to the length ; it is not so pointed in the spire, 
and the sculpture is different. 
A specimen (bleached) No. 3655, is from the Siam N.W. 
boundary. 
GLESSULA FEDDENI, n. sp. (Plate CLXII. fig. 15.) 
Locality. Shan Hills (Wm. Blanfordcoll.). Type. No.261.06.2.2. 
Shell elongately conoid, tumid, very glassy; sculpture: rather 
distant striation, closer and stronger on the apical whorls; colour 
rich ochre ; spire conic, flatly convex, apex blunt ; suture impressed ; 
whorls 7, sides convex, the last very ample; aperture oval; 
peristome outer lip thickened; columellar margin short, with 
considerable convexity. 
Size: maj. diam. 6°75; alt. axis 13-2 mm.

This is the shell Blanford refers to as perhaps distinct from 
crassilabris, Bens., J. A. 8. B. 1865, p. 95; it much resembles that 
species, but placed side by side the points of variation are readily 
seen. Another single specimen (No. 41.06.53.) occurs in the 
Blanford collection, much more slender in form, but with similar 
sculpture, which I consider a variety (Plate CLXIII. fig. 14). 
GLASSULA INEDITTS, N. sp. 
Locality. Shan Hills. Three specimens not named (W, 7’. Blan- 
ford collection). Type. No. 83.06.5.5. 
Shell oblong turreted ; sculpture: transverse close regular raised 
striation, embryonic whorls smooth; colour: the type and best 
preserved rich ochraceous on last whorl; spire elongate, sides flat ; 
suture impressed; whorls 7, regularly increasing, slightly convex ; 
aperture ovate, small; peristome outer margin thickened ; 
columellar margin short, terminating abruptly. 
Size: maj. diam. 4°5; alt. axis 9°5 mm.
