the sexual difference in dimensions that is so noticeable in 
C. b. javanensis. 
If not kept distinct the species should be classed with 
C. sinensis. It is, however, different in habits, being much 
more of a jungle species than that form.

The sexual difference in size is very marked but is not 
noted by Shelley in the British Museum Catalogue, probably 
owing to the fact that he has taken the measurements of two
