MOLLTJSCA OF INDIA, 65 



nearly flat, apex very blunt; suture well impressed; whorls 11, 

 sides flatly convex ; aperture broadly ovate ; columellar margin 

 very convex. 



Size : maj. diam. 7*0 ; length 22'75 mm. 



This species was found among Blanford's duplicate shells, the 

 box marked with above locality and with the note " intermediate 

 between temiisj^ira and jierteiniis" ; it differs quite sufficiently from 

 both and from hasseinensis to be distinguished. From the last, it is 

 far longer at the body-whorl, which is very swollen, its sides more 

 convex, and the apex is much larger. 



GlESSTTLA AKOTTKTOiniirOENSIS, n. sp. 



Locality. Akouktoung on Irawady, Pegu {W. T. Blanford). 

 Type. No. 2207.06.1.1 B.il. 



Shell elongately turreted ; sculpture scarcely any, just a trace 

 near apex below the suture; colour umber-brown; spire long, sides 

 flat, apex blunt ; suture impressed ; whorls 10, sides flatly convex ; 

 aperture ovate. 



Size : maj. diam. 6-75 ; length 20*5 mm. 



This species occurred among the duplicates in the Blanford 

 Collection. Compared with G. hasseinensis, it differs in sculpture, 

 in colour, and the last whorl is more tumid in proportion to the 

 length. 



Glessula peguemm, W. Blf. (Plate CLXII. figs. 20, 21.) 



Locality. Pegu. No. 8.9.3.15 {Hi/. Blanford). 



Original description : — " A. 2)cguensis, n. sp. Shell oblong ovate, 

 rather solid, dark reddish brown, horny, marked wirh distinct and 

 regular impressed lines. Spire convexly conical ; apex obtuse ; 

 suture impressed, subcrenulate. AVhorls 6i, slightly convex; -the 

 last ascending a little towards the mouth, and exceeding j of the 

 shell in length; aperture vertical, truncately semicircular ; peri- 

 stome obtuse, slightly thickened; margins joined by a callus; 

 columella very much curved, projecting forwards at the base, sub- 

 vertically truncated within the peristome. 



milliin, inch. 



" Length 7 0-28. 



Diameter 'd^ 0-14. 



Length of aperture 2| O'll. 



"Habitat. Irawady Valley, Pegu: common. 

 " A pretty little sjiecies, darker in colour than anv of its allies, 

 except perhaps A. gemma, Bens., and easily distinguished from all, 

 by the columella being more arcuate, also by its more acuminate 

 spire and blunter apex, and its much stronger sculpture." 



I give two figures of this shell, from authentic specimens in 

 Hy. Blanford's Collection, as there is some variation in form.
