Smaller than M. lyra, which it resembles in the form of the 

 muzzle and ears ; the posterior portion of the tragus is, however, 

 longer and more attenuated upwards, and more acutely pointed ; the 

 nose-leaf is shorter, with convex sides, hut the anterior concave disk 

 is considerahlj' larger, its external margin is thickened and adherent 

 to the muzzle beneath, and the base of the narrow longitudinal pro- 

 cess is cordate (Plate X. fig. 1). 



Thumb and wings quite similar to those of M. lyra ; but the inter- 

 femoral membrane is deeper, the calcanea stronger, and the wing- 

 membrane docs not extend so far down upon the foot. Colour and 

 distribution of the fur as in M. lyra. 



First upper premolar larger than in M. lyra ; in other respects the 

 teeth are similar in both species. 



The skull differs much from that of M. lyra and from the other 

 species of the genus in the narrow unexpanded frontals, and in the 

 complete absence of postorbital processes ; the mesopterygoid fossa 

 is divided longitudinally by a very weU-marked ridge (Plate X. 

 figs. 1«, Ih). 



Length, head and body 3"'4, ear l"-3, tragus 0"-8, forearm 2"-3, 

 thumb 0"-6, third finger 4", fifth finger 3"-l, tibia l"-25, foot 

 0"-6. 



Hah. Malay Peninsula (Malacca) ; Siam ; Philippine Islands, Ter- 

 nate, Celebes, Sumatra, Java, ? Ceylon. 



This is the only species of the genus extending into the Australian 

 Region, but it has been found only in those parts of that region 

 adjoining the Oriental Region, the avifauna of which shows a large 

 admixture of species from Java and Borneo with Australian forms. 

 The occurrence of this species in Cejdon is doubtful, for no specimens 

 from that locality are found in any of the museums. Mr. Blyth has, 

 however, stated that he had compared specimens from Ceylon with 

 those from Malacca and Java*; and his short description of the 

 form of the nose-leaf certainly agrees with the characters of M. 

 spasnui. 



* The specimens from Malacca and Java referred to by Mr. Blyth (Kelaart, 

 ^ Prodr. FauniE Zeylanicx.tpp- 36, 38) are still preserved in the collection of the 

 Indian Museum, Calcutta, and are undoubtedly referable to this species.
