Description

Closely allied to "Psammophilus dorsalis", from which it differs in the following particulars :—-Ante-humeral fold deeper ; scales on body a little larger, from 80 to 100 round the middle, the dorsals always distinctly keeled and imbricate ; the hind-limb reaches to the orbit or a little beyond; frequently a small spine behind the supraciliary edge, and a few scattered, slightly enlarged scales on the flanks ; size smaller.Young, olive-brown above, spotted or marbled with brown, and usually with a series of large, lozenge-shaped, dark brown spots with pale centres on the back and tail; the markings persist more or less in the female, but disappear in the male ; the adult male is coloured much like "P. dorsalis". In the breeding season (May) the head and anterior part of the body of the male become scarlet or red, the posterior parts nearly black. Common on many of the hills in Chota Nagpur, ascending Parasnath Hill to 4,500 fed, according to Annandale ; common also in the Godavari district, in the hills south of Madras and Salem district, and Travancore. Ferguson collected it at Talayar in Travancore at 7,000 feet. .Like "dorsalis", it is found only on rocks, but Annandale says that it occasionally enters dwellings. He states the breeding season is in April and May, when the head and fore-parts of the male assume a brilliant red colour, displays himself to the female, who remains concealed, by slowly walking along in onspiouous place alternately raising and nodding his head in a very solemn manner.
