Oricjinal description:— '■'■ Shell about 2i Hues in length ; whorls 8 ; 

 spire rather obtuse ; colour brown ; aperture rounded, margins 

 reflected and interrupted by the body-whorl. 



" Animal with four tentacles, buttoned at the tips, the upper 

 pair longest and bearing the eyes at the summit ; colour blackish." 

 {Iluiton, 1834.) 



" Shell cylindrico-pyramidal, with 6 whorls, minutely striate ; 

 body-whorl ventricose, the others gradually tapering to an obtuse 

 apex ; aperture ovato-lunate, lips sub-reflected and white within ; 

 a single tooth at the junction of the outer lip with the body-whorl ; 

 colour brown." (Hutton, 1849.) 

 Length 4-4*5, diam. nearly 2 mm.

In colour the shell varies from pale and dark corneous to fulvous, 

 in some cases even rufous ; it is usually more or less shining, and 

 there are from to 7 whorls, some specimens have a more elongate 

 spire than others and the body-whorl is somewhat ventricose. In 

 a small percentage of shells the parietal denticle near the upper 

 margin of the peristome is obsolete or even entirely wanting. 



Jickeli has united under the collective name of Bidiniimis 

 (jya2Kieris) faUa.v, Stay ,])ractica\\y all the forms of the genus known 

 to him at the time of writing, stating that the different species 

 have been based on characters which may occur in specimens from 

 the same locality. Bourguignat, as might have been anticipated 

 strongly protested against this method of uniting forms from the 

 four quarters of the globe under a common designation and pro- 

 ceeded to add another new species *. While admitting that the 

 various forms closely approximate each otliei-, on geographical 

 grounds alone I must consider it advisable to separate them,Mhile,
