This flying lizard has a hidden tympanum, and is thus referable to Bracun- 

 culus, Weigmann, but such a slight modification of the peripheral characters is not 



sufficient to constitute a sub-genus. 



This species has also been found in Assam, Pegu, and Siam, and through 

 Tenasserim to Penang. 



Genus Japalura, Gray. 

 Japalura yunnanensis, n. s. Plate LXXVI, fig.. 2. 



A rather large, conically spinose tubercle behind the superciliary ridge, with a 

 more or less developed ridge passing obliquely backwards on the occiput to the 

 origin of the nuchal crest. A prominent ridge of three to four large conical tubercles 

 behind the eye and over the hidden tympanum. Scales rather small, keeled and 

 imbricate, with a number of large scales scattered singly and in groups over the 

 side and back ; the tips of all directed obliquely backwards and upwards. Scales 

 of the under surface keeled, those of the throat small. Scales of under surface of 

 toes keeled. Those of the tail keeled ; the sub-caudals the largest. Nuchal crest 

 feebly developed, consisting of triangular lobes; it is prolonged along the back 

 as an obscurely serrated ridge, disappearing on the base of the tail. A fold across 

 the neck. In females (males not known) a longitudinal ridge of skin in the posi- 

 tion of the gular sack. About 45 scales in a longitudinal row from limb to limb. 

 Dentition in two females (1) -i^ + || = || and (2) ||- + |f = |f . The first female 

 is old and has lost some of the teeth of the lower jaw. Two canines in each jaw. 

 Hind leg extends in one specimen to near the eye, in another it does not reach the 

 mouth. General colour olive, with a tinge of brown. A well marked black band 

 with a yellow anterior margin from the posterior margin of eye to the angle of 

 mouth. Pive black transverse bands, somewhat irregular on the back, narrow and 

 distinct on the neck, but broad on the body, and separated from each other by narrow 

 olive-yellow bands. The large scales are chiefly distributed on these light-coloured 

 bands. Tail faintly banded brown and olive. Under surface uniform olive yellow. 



The two specimens which have served for the foregoing description are both 

 females from the neighbourhood of (Momien) Teng-yue-chow. They measured 

 about the same size : total length 10''' ; tail 7 inches.
