MOLLtrSCA OF IJfDIA, 13 



delicate, and glassy texture ; sculpture, rather di&tant well-marked 

 costulation ; colour whitish grey ; spire moderately high, sides 

 convex, apex blunt ; suture impressed ; whorls 6, tumid, sides very 

 convex, antepenultimate the largest ; constriction in centre, above 

 the aperture; aperture widely ovate, vertical, angulate on the 

 lower margin of the columella ; the tooth large and well developed ; 

 peristome very strong. 



" Size : maj. diam. 1"3 ; alt. axis 2-0 mm. 



"This is another minute shell, differing from all others I have 

 seen in the strong peristome and large columellar tooth. D. delicata 

 is its nearest ally."

 convex, penultimate and antepenultimate equal ; constriction in 

 front, above the peristome ; aperture circular, nearly vertical ; 

 columellar tooth very small and internal ; peristome closely double,

Locality. Margarita ( W. Doherty, in coll. T. H. Aldrich). 



Original description: — "Shell dextral, elongately ovate, thickened ; 

 sculpture, fine, close, regular costulation throughout ; colour pale 

 sienna-brown ; spire with convex sides, apex blunt ; suture im- 

 pressed ; whorls 6, sides convex, penultimate slightly the largest, 

 the last does does not rise much upon the penultimate ; constriction 

 in front, but not well marked ; aperture circular, suboblique ; colu- 

 mellar tooth well developed for the size of the shell ; peristome 

 double, strong. 



" Size : maj. diam. I'O ; alt. axis 1-5 mm. 



" This is a good species, one of the smallest ; its elongated form 

 separates it at once from D. parvula, the finer costulation and 

 larger size from D. minuta."
