Tbat a species originally described from Yunnan should be found 

 in Hupeb appears extraordioary. The fact may perhaps be explained 

 by assuming that Heude's species was not found at Talifu, but a few 

 miles north or east of that city, where the locality would be within 

 the watershed of the Kinchakiang (Yangtze). In spite of the great 

 similarity of C. clandus and C. spinula^ we believe in the validity of 

 the two species, since they are both found living at the same locality 

 — Changyang.
