LAND AND FRESHWATER 



largp ; suture well impressed ; whorls 9, sides nearly flat ; aperture 

 small, ovate; cohimellar margin very convex. 



Size : maj. diam. 8'0 ; length 30'25 mm. 



This species was also found on the Mekong lliver, paler ia 

 colour, with an ashy tint. No. 3748 B.M. 



Glessula woodthoepei, n. sp. (Plate CLXII. fig. 19.) 



Locality. Shan States. Nine specimens (Lt.-CoI.E. Woodthorpe). 

 Type. No. 1628 B.M. 



Shell oblong conoid, shiny, very smooth ; sculpture : distant, 

 rather coarse indistinct irregular strise; colour olivaceous; spire 

 elongately conic, apex blunt ; suture well impressed ; whorls 7, 

 gradually increasing, hody-whorl to length lOU : o5-6 : aperture 

 ovate, vertical ; peristome outer tip thickened ; columeJlar margin 

 slightly concave, short, strong, truncate. 



Size: m,<)j. diam. 5'75 : length 13'5 mm. 



This shell has a likeness to G. crassilabri.i, but the aperture is 

 smaller in proportion to the length ; it is not so pointed in the spire, 

 aud the sculpture is dilFerent. 



A specimen (bleached) No. 3655, is from the Siam N.W. 

 boundarj-. 



Glessttla peddeni, n. sp. (Plate CLXII. fig. 15.) 



Localittj. fiha.n Wills (nin.BlanfordcolL). Type. No. 26 1.06.2.2. 



Shell elongately conoid, tumid, very glassy ; sculpture; rather 

 distant striation, closer and stronger on the apical whorls ; colour 

 rich ochre ; sjnre 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. li-7o ; alt. axis 13'2 mm. 

 „ „ 6-0 ; „ „ 1-1-75 mm. 



This is the shell Blanford refers to as perhaps distinct from 

 cmssihibris, Bens., J. A. S. B. 1865, p. 95 ; it much resembles that 

 species, but placed side by side the points of Viiriation are readily 

 seen. Another single specimen (No. 41.06.3 3.) occurs in the 

 Blanford collection, much more slender in form, but with similar 

 sculpture, which I consider a variety (Plate CLXIII. fig. 14).

 ford collection). Type. No. 88.06.5.5.

 striation, embryonic whorls smooth; colour: the tvpe and best 

 preserved rich ochraoeous on last whorl ; spire elongate, sides flat ;
