CoPHOTis CEYLANiCA. (Plate XIII. fig. H.) 



Cophotis ceylanica, Peters, Monatsber. Berl. Acad. Dec. 1861, p. 1103. ■, 



Head tetrahedral, rather narrow, with the snout somewhat produced and pointed ; body 

 and tail compressed, the latter slightly prehensile. The upper surface of the head is covered 

 with small, iiTegular, rather convex shields. Nose of the male mth a small obtuse tubercle. 

 Nine upper and eight lower labials ; nostril lateral, situated in the hinder half of a small 

 shield. Eye rather small, eyelid scaly. Longitudinal series of quadrangular scales on each 

 side of the gular sac, which in both sexes is but little developed. Nuchal crest composed of 

 three compressed triangular scales, not continuous with the dorsal crest. The dorsal crest 

 is composed of about twelve similar, distant scales, which are much larger in the male than 

 in the female. The upper parts of the trunk covered with very large imbricate scales, 

 irregularly arranged, but with their points directed downwards and backwards ; some of them 

 are keeled. Ventral scales small, strongly keeled. The scales on the upper parts of the tail 

 similar to the dorsal, those on its lower surface similar to the ventral scales, their keels 

 being continuous. Limbs moderately developed ; the hind limbs extend on to the shoulder, 

 if laid forwards. Toes with non-carinated transverse scales below ; the tliird and fourth 

 hind toes are nearly equal in length. Fawn-coloui-ed, with irregular broad bro^vn cross 

 bands ; tail nearly white, with brown rings ; a white spot in front of the nuchal crest and a 

 white band running from the angle of the mouth to the shoulder are more distinct in the 

 male than in the female. Jaws with a broad brown margin ; throat white, with one or two 

 oblique brown streaks on each side. 



This species must be rare and very locally distributed in the island of Ceylon, as it has 

 escaped the observation of Kelaart. Two beautiful specimens have lately been procured 

 for the British INIuseum, male and female of nearly the same size, 6 inches long, the tail 

 measuring of inches. It is evidently a Tree Lizard. 



JAPALURA. 



Japalura et Biancia, Gray. 



Tympanum hidden. The upper parts covered with small, imhricate, keeled 

 scales, hetween which larger ones are intermixed ; dorsal crest low. Tail 

 slightly compressed at its base. Throat with a small pouch in the male, and 

 with a transverse fold. No rostral appendage. Ventral scales of moderate 

 size, keeled ; scales below the tail as broad as.Jong. 



The geographical distribution of this genus is very singular, one species being found in
