XXVII. REPTILIA (Supplement). 



By N. Annandai^e, D.Sc, F.A.S.B., Superintendent, Indian 



Museum. 



In a small collection of lizards and snakes made in the Abor 

 country after the conclusion of the main expedition by Capt. Sir 

 George Duff-Sutherland-Dunbar, and presented by him to the Indian 

 Museum the following species are represented : — 



Lizards. ^ Snakes. 



Japalura andersoniana , Annand. , Trachischium moitticola (Cant.) , 

 Ophisaurus gracilis (Gray), Callophis macclellandii (Reinh.). 



These species were all taken between lat. 28° 45' and lat. 

 29° N. at an altitude of about 4000 ft. By far the most interesting 

 specimen is an adult male of the Agamid Japalura andersoniana. 

 As this lizard was hitherto known only from two half-grown indi- 

 viduals taken in the Dafla Hills many years ago by Col. Godwin- 

 x^usten, a new description of the species has been drawn up. 



Japalura andersoniana, Annandale.

Body slender, strongly compressed. 



Limhs long; hind limb reaching tip of snout *or beyond; 

 digits, especially those of the hind feet, very long and slender. 



Head moderate ; snout in adult distinctly longer than diame- 

 ter of orbit, bluntly pointed; rostral and superciliary ridges pro- 

 minent, continuous, followed behind, after a slight interval, by a 

 prominent tubercle bearing several small scales ; several prominent 

 scales scattered on the sides of the head behind the eye ; dorsal 

 surface of the head between the eyes deeply concave ; dorsal and 

 lateral surfaces of snout slightly so, with a well defined median 

 Y-shaped ridge on the former. No gular pouch or distinct gular 

 fold. 



Dorsal crest. — Crest on neck well developed, consisting of a 

 fold of skin as deep as the diameter of the eye, having several ver- 

 tical pleats, covered with small leaf-shaped scales and bearing a 

 row of slightly larger lanceolate ones along its upper margin ; 

 crest on back consisting of a single row of similar scales without 

 the fold of skin at their base. 



Scales on dorsal surface of snout irregular, nearly smooth, on 

 superciliary region larger and strongly keeled. Lateral scales on 

 body for the most part small and not very stronglj^ keeled, in the
