MAMMALS COLLECTED IN SIAM. 361 
This species is apparently the common flying-fox of Bangkok, 
whence no other has been recorded. It has been taken at Petcha- 
huri to the south-west and extends eastward to Saigon. 
(For measurements see table posted.) 
17%. Cynopterus angulatus. 
Cynopterus angulatus, Miller, Proc. Nat. Acad. Sci. Philadelphia, 1898, 
p. 316. 
Cynopterus brachyotis angulatus, Andersen, Cat. Chir. Brit. Mus. 
1, p. 611 (1912); id. P.Z.S. 1916. p. 40; Wroughton, Journ. 
Bombay Nat. Hist. Soc. XXTII, p. 702 (1915). 
3d ad., 52 ad., 12 subad. Bangkok, Oct. 1916. 
None of the animals in this series exhibit a sagittal crest 
but all seem adult except the last. 
Leaving the ears out of the question—measurements of 
which may be rendered inaccurate either through the. personal 
equation of the worker or through distortion in preservation—these 
specimens are evidently not sphinx, judging by the ratio of rostrum 
to length of skull, as in that species the length of the rostrum (orbit 
to nares) is more than one-fourth the total length (fide Andersen, 
op. cit. p. 612). 
I record them therefore as C. angulatus, though the ears are 
large while the other dimensions show that they are equal in size to 
smaller examples of sphinx (see below). The measurements of three 
adults collected by Mr. G. C. Shortridge at Tenasserim Town and 
Bankachon, Tenasserim, are also given.
