metacarpals, and phalanges of about the same length aa tlio large=;t 

 specimens of brachijotis ; the diiference in the size of the skull and 

 teeth of the two forms is much less conspiuuous. From C. h. 

 javanicus the present race differs bj- its larger average size and 

 relatively longer metacarpals and phalanges. Compare the table, 

 p. 622. Colour of fur as in G. h. hrachyotis (p. 618).

Differential characters. — Like C. h. hrachyotis, but cranial 

 rostrum relatively longer, Pg and p' averaging slightly heavier, 

 tooth-rows longer. See table, p. 622. 



Ceylon is inhabited by two forms of Cynopterus, C. sphinv spihinx 

 and C. h. ceylonensis ; the former is common to the Indian Peninsula 

 and Ceylon, the latter a local representative of an otherwise exclu- 

 sively indo-Malayan species and so closely similar to G. h. hrachyotis 

 (Malay Peninsula, Sumatra, Borneo, etc.) as to differ only by trivial 

 average characters. The rostrum of ceylonensis is very nearly equal 

 to, in hrachyotis usually decidedly less than, one-fourth of the total 

 length of the skull; the dentition, particularly the third premolars
