XIO Mr. J. E. Gray on Reptiles 



theless Cuvier gives the name of Roquet to a species of his genus 

 Anolis, which by the way is not the Anolis of Rochefort but his Gobe- 

 mouche, so that the confusion is almost inextricable;" and he further 

 observes, " the under side of the belly and legs is of a dirty cream- 

 colour, becoming yellowish towards the extremity of the tail. The 

 underside of the head and breast is marbled gray, as is the upper side 

 of the head, and about 26 or 28 transverse faint dorsal bands, which 

 on the dirty cream-colour ground become more conspicuous as they 

 approach the extremity of the tail ; its colouring in short is exactly 

 that of the gray Madrepores which it haunts, and into the cavity of 

 which it retires when alarmed. The largest I have seen have been 

 more than a foot long," This description of the colouring shows 

 how it difTers when alive from the specimens we have to examine 

 in spirits. 



They live on the sea-coast : for Mr, MacLeay, when speaking of 

 the sandy shore behind the belt of coral reefs, observes, " Here gray 

 lizards of different sizes with saffron bellies and tails curled in spiral, 

 peep from under the dusky flat stones which are generally sea- broken 

 and time-worn pieces of Madrepores." 



Tropidxjrus. 



3. Tropidurus (^Leiolamus), Cubensis, n. s. 



Head shields many, keeled and imbricate. Scales of the back and 

 sides broad rhombic, keeled ; the keels forming oblique lines ; back 

 and tail slightly crested. Ears moderate with 3 or 4 scales in front. 

 Temples with small keeled scales (discoloured) blueish chin and 

 throat blueish white spotted ; belly and underside of tail white. Two 

 series of scales over the upper labial plates, the plate immediately 

 under the eye of the upper series large, elongated. The underside 

 of the toes with 3 or 4 keels. 



Anolius, 



The genus Anolius may be divided into genera and sections to faci- 

 litate the distinction of the species ; and in making these divisions I 

 have not adopted the characters used by MM. Dumeril and Bibron, 

 as I found the table of the species given in their work of very little 

 use to me for making out the species. Most of the specimens in our 

 collection have the scales of the sides smaller than those of the back 

 and belly, while these naturalists place only a single species as having 

 this character. 



The genus may be thus divided : — 



I. XiPHosuRUs, Fitzinger.
