Zang has suggested that Kuwert's C. masoni of 1897 is not StoHczka's, and that 

 the latter is identical with Kuwert's C . angusticornis ; an examination of the type 

 of C. masoni, and of specimens determined by Kuwert, has confirmed the former 

 suggestion but not the latter.

Kuwert's 1891 record "Lahore " is doubtless a mistake, as he appears to have 

 been unacquainted with the species at that time except through StoHczka's account 

 of it.

' These records are based on specimens in Berlin which I did not see in time to include any account 

 of them in part 4 of this paper. 



^ There is a single specimen from this locality in the British Museum ; it is less distinct from 

 C. cylindraceus than the specimens I have seen from the Malay Peninsula, the anterior part of the 

 central tubercle, though much elevated, being angular beneath; it may perhaps belong to a distinct 

 local race.
