In older specimens the median dorsal region is bright rufous. 

 Underparts light. 



Remarks. — This species is decidedly iguaniform, but the digits are 

 too short for an arboreal habit. A comparison of this species with 

 its nearest relatives, erythromelas , darki, and quinquecarinata, is given 

 under the discussion of the former. 



Material examined. —
