his trip to Mount Orai, in Sytshouan. The exact locality is not 

 known, but it must be in either Hupeh or Sytshouan. 



The inner ends of the lamella spiralis and the lamella inferior run 

 out nearly parallel ; the former is only slightly shorter than the 

 latter. As regards shape, size, and colouring, the species may be 

 compared to C. adaucta, Gredl., but it has a smaller aperture, more 

 receding at the base, the largest diameter of which is oblique to the 

 axis. The lamella spiralis is less high in the interior, and, above all, 

 the plica principalis is shorter by half, and placed far back ; below the 

 plica pi'incipalis, as well as at the base near the lamella subcolumellaris 

 (which is visible through the shell), are two very short and fine thick 

 palatals. 



C. Tetsui differs from our species even more than C. admicta, viz. in 

 the sculpture being totally different, and in having a long plica 

 principalis.

It reminds one of a very slender form of C. adaucta, Gredl. ; it 

 is, however, more obsoletely striated, the apex is less pointed, the 

 lamella subcolumellaris is more exserted, distinct upper and lower 

 palatal plicoo are absent, the plica principalis almost reaches the 

 peristome, which, below the exceptionally small sinulus, has a strongly 

 developed callosity, protruding into the aperture.
