The Jlromastiai leaves its burrow, when the sun is well up, and 

 grazes about for some time, retreating during the midday heat. 

 Towards evening it reappears : retreating again, as the air grows 

 dhilly, and closing its burrow carefully for the night, with sand. 

 When captured they assume a very peculiar and resigned expres- 

 sion of countenance, and offer little resistance when held in the hand. 



Phrynocepkalus has all the appearance of being a third genus 

 of their family, but I am not certain if it is herbivorous or not.

 granular. Tail long, prehensile. Feet zygodactylous. Eyes 

 globular, prominent, covered by a circular lid pierced by a small 

 central hole, capable of independent motion. Tympanum 

 hidden. Tongue exceedingly long, wormlike, highly viscous 

 at the tip and capable of protrusion and retraction with lightning 

 speed. Arboreal^ oviparous. 



C. vulgaris' L. 



Ridge of back and belly denticulated. Occiput With a pro- 

 minent longitudinal crest highest behind and separated from the 

 nape by a deep groove. Colour pale green, uniform or mottled

These curious lizards may be easily studied in captivity, if well 

 supplied with grasshoppers, crickets, dragon flies, blattse and other 

 large nutricious insects — which they seize by darting their tongue 

 on to them from a considerable distance. The telescopic and 

 unconnected movements of the two eyes is without parallel in any 

 other Family of Reptiles. But one species is known in India.
