 smaller ; breast and belly usually blackish or seal-brown (as

Specimens examined. Nine, in the collection of the Berlin 

 (Bangkok specimens) and British Museums (Fechabun, 

 Bangkok, Saigon). 



Range. Siam (Pechabun, Bangkok) ; Saigon. 



Remarks. — This species probably re|)laces Pt. giganteus in 

 Siam, Cambodja, and Cochin-China. The Bangkok speci- 

 mens in the Berlin Museum were catalogued by Matschie 

 (' Megachiroptera,' p. 26 ; skull figured, pi. iv. fig. 8 ; 1899) 

 under the name Pferoj>M.5 [Spectrum) assamensis ; McClelland^s 

 Pt. assameiisis is, however, the Himalayan race of Pt. gigan- 

 teus, Pt. g. leucocephalus, Hodgson.
