[1] The upper head-scales of M. ellioti are feebly keeled, imbricate, and much enlarged on the supraorbital region.

There is a small spine behind the supraciliary edge, and two others on each side, the anterior midway between the nuchal crest and the tympanum, the posterior just above the latter, which measures nearly half the diameter of the orbit.

The nuchal crest is composed of a few widely separated slender spines, the longest of which measures about two thirds the diameter of the orbit.

The adpressed hind limb reaches the anterior border of the orbit or the tip of the snout.

M. ellioti is olive above, with more or less distinct angular dark-brown cross bands on the body.
