Head long, broad, and flat posteriorly, wide, and elevated 

 between the eyes, suddenly contracting and sloping to the snout ; 

 eyebrows hardly keeled, no facial ridge. Back with small 

 snbcarinate scales in cross rows and numerous larger ones inter- 

 mixed ; ridge-like folds above and below the ear ; nape with a 

 low crest continued rudimentarily to the tail. Tail short, 

 tapering, with the keels of the scales above, and for the most 

 part below, in continuous lines ; scales of the lower surface 

 subcarinate ; throat with a cross fold ; femoral and preanal 

 pores ? A genus differing from the other genera of the Agamidao 

 rather in the totality of its characters than in any salient feature. 



MACEOPS NUCHALIS. 



The length of the head is 3|, that of the hind limb of the 

 fore limb 3i, the distance between the limbs 2, in the length of 

 the trunk. Snout If in the interorbit, interorbit If in the length 

 of the head. Tail, a tenth longer than the head and trunk. The 

 profiles of the snout and interorbit convex : postorbital part of 

 the head broad, flat, not distinct from the neck ; a keeled fold 

 from below the orbit runs over the ear, and below it a shorter 

 one, also over the ear ; a more distinct one from below the angle 

 of the mouth armed with triangular free scales runs under

 pentagonal, the rest rhombic. Scales of snout carinate, of the 

 rest of the head smooth ; of the back and belly subcarinate ; 

 nuchal crest composed of six or seven low free scales ; the
