Previously it has only been known from the Semangko Pass on the Selangor— 

 Pahang boundary and the record of this species from Northwestern Siarn adds a consid- 

 erable distance to its distribution to the north. 



The cheek teeth are conspicuously narrower posteriorly than anteriorly and the 

 surface cusp on p 4 and m, is well-developed. These are the main points of character- 

 istic for Cynopterus harpax Thos & Wrought, and it is without hesitation that I 

 have identified my specimens as belonging to that species.

Rhinolophus coelophyllus. Peters. 



$ Koh Lak, Siamese Malaya 3 /i 2 1914. — Forearm = 41,4 mm. — <f (alc.) Koh Lak 3 /is 1914. — 

 Forearm — 41,2 mm.; Ear = 14.:> mm. 



Apparently rather common at the neighbonrhood of Koh Lak where numbers of 

 these båts were seen flying among some low bushes near the sea shore just at dusk. 



As far as I know it has not been recorded from Siarn before, but specimens have 

 been obtained both in Burma and in the southern parts of the Malay Peninsula (Kedali).
