I am not able to detect in the description a single character of 
sufficient importance to justify a separation of this form from A. 
leachti. A careful comparison of the types alone can show whether 
it is to rank as a species, or merely as a variety of A. leachii.

Head moderate, once and two thirds to once and three fourths 
as long as broad, longer than the tibia; snout rather strongly de- 
pressed, forehead concave; no frontal ridges; upper head-scales 
smooth ; scales of the supraorbital semicircles strongly dilated, in 
contact with each other and with the occipital, which is larger than 
the ear-opening ; six to ten enlarged, smooth or indistinctly keeled 
supraocular scales, separated from the supraorbitals by one row of 
granules ; canthus rostralis sharp in front of the eye, otherwise 
rather obtuse ; canthal scales four or five; loreal rows four or five; 
five or six labials to below the centre of the eye; eye-opening 
moderately large, vertically suboval. Gular appendage rather large, 
not developed in the female; gularscalessmooth. Body compressed, 
in the male with a feeble dorso-nuchal fold. Dorsal scales small, 
granular, keeled, larger and more distinctly keeled on the vertebral 
region; ventral scales larger than dorsals, roundish hexagonal, 
feebly imbricate, smooth or indistinctly keeled. Limbs moderately 
long; the adpressed hind limb reaches the temple or the posterior 
border of the orbit ; digital expansions well developed; twenty-two 
to twenty-six lamelle under phalanges 11. and 11. of the fourth 
toe. Tail compressed, with feebly and equally serrated upper edge ; 
its length not twice that of head and body. Male without enlarged 
postanal scales. Brownish or greenish above, frequently with a 
darker network enclosing small round whitish spots ; lower surfaces 
whitish or greenish, with metallic gloss.
