septiration. Compared with typical urnula, Bs., from Darjiling, 

 it is more solid and siiioother, costulate sculpture on last whorl 

 somewhat stronger, the umbilical imirgin more circumscribed, 

 peristome solid, and particularlv in the distance from base of the 

 sutural tube to the peristome being very short, forming the con- 

 stricted part of the whorl, when it 'is compared with typical 

 D. urmda from Darjiling and the \ariety from the Xaga Hills, etc. ; 

 it thus ap|)roaches the constriction of D. amj>liora'' (Godiuin- 

 A listen.)

Orir/inal description: — "Shell ovatelv globose, elongate, no 

 perforation ; sculpture : costulation next the sutural tube very tine 

 and close, rest of shell finely striate; colour bleached; spire high, 

 apex small ; suture impressed, the sutui-al tube moderately long : 

 in the drawing made from the first specimen received .... 

 this is represented too short, the end being broken ; whorls 4^, 

 sides rounded ; constriction short behind aperture ; aperture oval 

 Aertically ; peristome simple, double, rather solid. 



"Major diam. 4*8; alt. axis 4"25 mm.'"

"This species differs considerably from typical urmda in being 

 far larger and so high in the spire, urmda being more globose and 

 depressed; from another Abor species of this subgenus it may be 

 known at once by its less tumid globose shape and the peristome 

 being far less thickened.'' (Godiuin- Austen.)
