 nearly smooth, uniform corneous. Spire cylindric, slightly 

 acuminate, rather long. Apex strong, paler, very obtuse. 

 Whorls 7, somewhat convex, slowly increasing, separated by a 

 little impressed suture, the last whorl a little larger, convex, 

 rather swollen below. Aperture slightly oblicpie, slightly 

 lunate, suboblong ; columella straightened a little ; peristome 

 paler, straight, slightly expanded. Length 4, diam. 2 mm.

According to M. Margier (Feuille Jeunes Naturalistes, 

 Annee 40, p. 160) this is a Lauria. 



Lauria dadion (Bs.). Page 64. 



"A single specimen, taken alive [on Mt. Manotsuri, Shil- 

 wane district, 4,000 feet] , gives a remarkable extension to the 

 limited range of this species. In L. dadion, as well as in its 

 near allies L. farquhari and L. tabularis (M. & P.), there is 

 frequently a slight, bluntly pointed swelling half-way up and 

 rather deep-set on the columella, showing through the shell as 

 a white line observable within the umbilicus; in Junod's shell 

 this swelling is more prominent than in any other of twenty 

 which I have examined from Cape Town and Karkloof, and 

 seems to be represented by a clear furrow, rather than a white 

 line, in the umbilicus; it will be interesting to see whether 

 this variation is constant if further examples are ever col- 

 lected in the same neighborhood" (M. Connolly, Proc. Malac. 

 Soc. Lond., XV, Dec, 1922, p. 76).
