a small bony process from the symphysis of the mandible, was 

 separated by Dobson as Phyllorhina masoni ; but in his British 

 Museum Catalogue he states that the differences are probably 

 merely individual peculiarities. 



Habits. This species, like other members of the genus, haunts 

 rocky caves, old tombs, and other buildings; Kelaart found it 

 swarming in a tunnel cut through a rocky hill near Kandy.

Phyllorhina nicobarensis, Dobson, J. A. S. B. xl, p. 262, pi. xx, fig. 2 

 (1871) ; id. Man. As. Chir. p. 63 ; id. Cat. Chir. S. M. p. 138 ;

" 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

(? forward) and overhanging the concave front surface, which is 

 divided into two 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 metatarsal bone of the 

 outer toe ; tail of six vertebras, the last free. 



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

 light brown extremities ; beneath pale brownish grey." 



Dimensions. Head and body 3 inches, tail 1'7, ear from origin 

 of outer margin 0*9, forearm 2'6. 



Distribution. Nicobar Islands. The only specimen known was 

 procured by Dr. Stoliczka and is preserved in the Indian Museum, 

 Calcutta. 



The above description is copied from Dobson ; the form re- 

 sembles H. diadema, but is distinguished by the posterior leaf being 

 only divided into two cells, by the different attachment of the 

 wing-membrane, and by much smaller size. From the figures it 

 appears that there are three supplementary leaves on each side of 

 the horseshoe, and the sella appears to have a prominent median 

 ridge.
