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. occipENTALIS. There is no difference in the skulls.
