138 RHINOLOPHID^. 



? Var. a. 



Phyllorhina masoni, Dobson, Journ. Asiat. Soe. Beng. 1872, p. 838 ; 

 Monogr. Asiat. Chiro-pt. p. 62, fig. (head), 1876. 



The concave front surface of the erect nose-leaf divided into two 

 cells only by a single central vertical ridge. From the under surface 

 of the symphysis of the mandible a small conical bony process 

 projects dovrowards, about equal to the lower canine tooth in ver- 

 tical extent, and covered by the integument. 



Length, head and body 3""65, tail l"-65, ear 1""1, forearm 3""35, 

 thumb 0"'6, third finger 5", fifth finger 3"-9, tibia l"-35, foot 0"-65. 



Hah. Moulmein, Burma. 



Such are the characters of a single specimen, an adult male, pre- 

 served in the collection of the Indian Museum, Calcutta. Together 

 with the absence of the vertical ridges dividing the front surface of 

 the erect nose-leaf on either side of the central ridge is associated 

 a slight difference in the relative measurements of the bones of the 

 extremities, and the occurrence of the peculiar process from the 

 mandible described above. In other respects, however, this speci- 

 men agrees so closely with typical examples of Pli. diadema that I 

 now believe the differences in structure exhibited by it are, probably, 

 individual peculiarities only. 



9. PhyllorMna nicobarensis. 



Phyllorhina nicobarensis, Dobson, Journ. Asiat. Soc. Beng. 1871, 

 p. 262, pi. XX. fig. 2; Monogr. Asiat. Chiropt. p. 63, figs, a, h 

 (head and nose-leaf) (1876). 



Ears large, acutely pointed, outer margin slightly concave beneath 

 the tip ; no frontal sac behind the nose-leaf ; upper margin of the 

 transverse leaf simple, forming an arc of a circle, folded back and 

 overhanging the concave front surface, which is divided into tivo 

 cells only by a single central vertical ridge ; in front the margin of 

 the horseshoe has three small points. 



"Wing-membrane from the base of the inetacarpal bone of the 

 outer toe ; tail of six vertebrae, the last free! 



Fur, above, light brown at the base, then greyish brown, with 

 light brown extremities ; beneath pale brownish grey. 



Length, head and body 3", head 1"-1, tail l"-7, ear 0"-9, forearm 

 2"-6, third finger 3"-7, fifth finger 2"-8, tibia 1", foot 0"-45. 



Hah. Nicobar Islands. 



Tj'pe in the collection of the Indian Museum, Calcutta. 



This species resembles Ph. diadema generally, but is at once 

 distinguished by the erect nose-leaf being divided in front by a 

 single vertical ridge only, by the different attachment of the wing- 

 membranes to the hinder extremities, and by its much smaller 

 siTie.
