The type of C. matschie in the Berlin Museum was examined 

 and no difference could be perceived between it and the present species. 

 It is claimed that the white tuft is smaller, but in the type it is one 

 third the length of the tail, just what Rochebrune says is the length of 

 the tuft in C. occidentalis There is no difference in the skulls.
