ANAUCHEN. 191 



"This species is quite nearly related to the following 

 (Hypselostoma crossei) , in company with which it appears to 

 live. It differs by the more slender, narrower spire, the less 

 developed last whorl, the more superior angulation of which 

 disappears entirely towards the aperture ; finally by the posi- 

 tions and number of the teeth" (MabUle). 



It has not been figured, but from the description seems re- 

 lated to gereti. I suspect that there is a deeply placed colu- 

 mellar lamella. 



4. ANAUCHEN ANGULINUS (Gredler). PL 33, figs. 5, 6. 



Shell thin, perviously and widely umbilicate, trochiform, 

 spire conoidal; apex obtuse; very weakly striatulate, silky, 

 pale corneous; whorls 6, convex, the last rapidly increasing, 

 hardly ascending, obtusely angular at the periphery and um- 

 bilicus; aperture diagonal, ample, rounded-tetragonal, tooth- 

 less except for a simple, low and short parietal fold; 

 peristome very thin, broadly expanded, slightly reflected, the 

 margins joined by a callous which is adnate in the middle 

 and arcuately extended towards the left. Alt. 3%, basal 

 width 2% mm. (Gredler). 



China: Hunan or Hupe.

 museums, ii, 1887, p. 285, pi. 11, f. 22, 23. 



This species appears to have some resemblance to A. gereti, 

 but the teeth are reduced to a single parietal lamella. I have 

 not seen it.
