Synopsis of the Species. 
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 ............ sister ha ad et haa Reta 1. asper. 
Tail nearly as long as the fore limb, as long as the 
head ; rostral and mental subequal .......... 2. levis, 
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. platyurus, 
2. Nephrurus levis.

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,
