OF NEW SOUTH WALES. 103 



39. — TlARIS Longii. 



This species answers in many respects to the description I have 

 given above of the last species, I shall therefore only notice the 

 points in which the two species differ. 



Head black, depressed between the eyes . and widely furrowed 

 on the occiput with a very small occipital plate ; rostral shield 

 not emarginate above, with four small square, smooth plates 

 behind ; under rostral subtriangular ; upper labials long and low ; 

 lower labials 9 ; angle of the head under the ear much swollen, 

 and with only a few large scales or plates ; gular pouch entirely 

 black, longitudinally folded, with a cross angular fold behind ; 

 crest scales not so long on the neck before the interruption as in 

 the last species but more numerous, on the back high and a 

 little arcuated, on the tail lower and ceasing at one-third of the 

 length ; general colour, brown above, with a few yellow marks, 

 and dingy brown below, getting lighter towards the tail, which is 

 much compressed and faintly ringed with brown and yellow. 



Total length, 2 feet 4 inches, tail 1 foot 10 inches. 



This is the first of the genus I have heard of as being found 

 in Australia. 



My specimen was presented to my Museum by Mr. Mark H. 

 Long, of William-street, after whom I have named it, and was 

 taken in some part of Northern Queensland.

 or less with smooth, ivory-looking scales ; the posterior angle of 

 the head under and behind the ear armed with a compressed, 

 sharp-edged, protruding ivory-looking process ; an erect crest of 

 compressed, triangular, obtusely-pointed scales on the nape, con- 

 tinued along the back and beginning of the tail by shorter com- 

 pressed, spiny-pointed, firm scales ; all the scales keeled, those 

 on the legs, ventral surface and tail largest ; the whole upper
