Synopsis of the Sjiecles. 



Tail about half the length of the fore limb ; gular 

 region with rosettes of enlarged tubercles ; nine 

 or ten tubercles across the middle of the inter- 

 orbital space ; rostral nearly twice as broad as 

 mental 1. asper. 



Tail nearly as long as the fore limb, as long as the 



head ; rostral and mental subetjual 2. Icevis. 



Tail a little longer than the fore limb, longer than 

 the head ; gular region with uniform fine granules ; 

 four tubercles across the middle of the interorbital 

 space; rostral and mental subequal 3. platimrtis. 



2. Nephrurus laevis. 



Nepbrurus levis, I)e Vis, Proc. Linn. Soc. N. S. W. (2) i. 1880, 

 p. 168. 



Snout as long as the diameter of the orbit ; ear-opening a vertical 

 slit, measuring half the diameter of the orbit. Limbs rather short. 

 Tubercles on the occiput, interorbital space, and sides of the frontal 

 region largest ; rostral and mental subequal, small and low ; 20 upper 

 and as many lower labials. Upper surface of body and limbs minutely 

 granular, studded with small rosettes composed of a conical tubercle 

 within a circle of very much smaller and numerous tubercles ; the 

 rosettes are for the most part irregularly disposed, but on the flanks 

 they tend to arrange themselves in oblique lines ; they also form a 

 regular curved line across the back and a less definite angular band 

 across the shoulders ; lower surfaces covered with small tubercles 

 which enlarge a little on the chest and towards the lip. Basal two 

 thirds of the tail expanded and flat on the upper surface, the breadth 

 of the expanded portion two thirds of the length of the same, sud- 

 denly contracting to a tapering peduncle bearing a small pyriform 

 knob. Above light brownish grey ; a pale band across the occiput,
