] 28 EHINOLOPHID^,. 



First upper premolar minute, blunt, in the outer angle between 

 the canine and second premolar, rarely deciduous. 



Range. Tropical and subtropical regions of Asia, Malayana, Aus- 

 tralia, and Africa. 



The species of this genus are, unlike Rliinolophus, inhabitants of 

 the plains and low hill-ranges of the warmer regions of the conti- 

 nents and islands of the eastern hemisphere lying within the tropical 

 and subtropical zones. The largest Asiatic species, Phyllorhina 

 armigeni, Hodgs., appears to be the most northerly, having been ob- 

 tained by Mr. Swinhoe at Amoy, in China, and by the late Captain 

 T. Hutton at Mussooree, in the Himalaya, at an elevation of 5500 

 feet ; P. bicolor is also said to have been taken by Capt. Hutton at 

 the same elevation ; but these are exceptions among the great number 

 of species of this genus.
