Original description : — •' Shell small, depressedly aud globosely 

 conical, well umbilicated ; sculpture : strong, distant, and regular 

 costulation above, close and stronger next the sutural tube : 

 colour whitish ; spire rather low, apex blunt ; sutui-e impressed, 

 the sutural tube fairly long ; whorls 3|, well rounded, the last is 

 well co)istricted in front of base of sutural tube, then rises into a 

 low but defined diagonally directed ridge and spreads forward, 

 showing externally the shallow crenation \'\ith a decided notch 

 next tlie sutural side ; aperture irregularly ovate, suboblique : 

 peristome double, crenulated on the upper and outer margin, 

 not so below, and the columellar side rounded and suboblique ; 

 the crenulatiou is not deep, and the first upper fold extends 

 forward and is the most conspicuous. Such is the description of 

 the peristome of the type, but it is evidently not at full develop- 

 ment. In the second example four well-defined notches and folds 

 are seen, the lowest central and basal.

" . . . . size does not count for much, but this little Garo 

 Hills shell also differs from typical crispatus by its much more 

 depressed and different shape." {Godwin- Austen.)
