 tion are indistinguishable from the cotj'pes of Pt. leucocephalus. — 

 The bat described by Matschie under the name Pt. assamensis, 

 McClelland (Megaohir. p. 26, pi. iv. fig. 8, 1899), is Pt. lylel.

Diagnosis. — Closely allied to Pt. giganteus, but rostrum broader 

 anteriorly, dentition heavier, size slightly smaller, interfemoral 

 shorter, second phalanx of fourth and fifth digits relatively longer. 

 Colour of fur as in Pt. giganteus. Forearm about 160 mm. Hah. 

 Maldive Archipelago. 



Skull. — Total length as small skulls of Pt. giganteus, but 

 rostrum very short, broad, and less tapering anteriorly, the width 

 across external surfaces of upper canines only slightly less than 

 across lower edges of lachrymal foramina ; palate relativelj* broader 

 than in the continental species. 



Teeth. — Heavier than in Pt. giganteus, notwithstanding smali 

 size of skull, but not differing in structure ; p^, length 5-7 mm, 

 (4-2-5 in twenty-five skulls of Pt. giganteus), width 3-8 (3-l-3"7) , 

 p,, length 5-6 (4'2-5'2), width 3*1 (2"8-o-4); m" unusually large, 

 Tor further details see measurements of teeth, p. 338. 



Wings. — Second phalanx of fourth and fifth digits, in the single 

 British Museum specimen as well as in the type (see Allen'a 

 measurements, I. s. c). much longer than, in Pt. giganteus generally 

 subequal to or shorter than, first phalanx of same digits. 



Interfemoral. — In the single specimen examined considerably 

 shorter than in Pt. gigante%is ; depth in centre 12 mm., against 

 170-25.
