Messrs. Dumeril and Bibron, I have added to the paper a 

 description of them.

" Found in the Isle of Pines, where it occurs of a large size nearly 

 4 feet long, and in great numbers. It runs with extreme velocity : 

 becomes easily domesticated. In confinement it would not eat any 

 kind of meat, but was very fond of bread and biscuit." — W. S. M.

Roquet of Rochefort Hist. Nat. and Mor. des Antilles, 131. 



Bibron by mistake refers my Leiocephalus carinatus to his Holo- 

 trophis Herminieri, which has according to his description and figures 

 the ventral scales strongly keeled. He considers that this specimen 

 is the same as Tropidurus Schreibersii of Fitzinger's Catalogue. 



The Cuban specimen agrees exactly with the specimens on which 

 the species was established, except in being rather larger and in 

 having one large in the place of 3 or 4 small pjates in the centre of 

 the muzzle behind the nose. 



A second younger specimen has the smaller frontal plates rather 

 different from either of the other specimens, and the tail is regularly 

 brown -banded. It has no anterior odd plates between the two an- 

 terior pair. 



This animal is the Roquet described by Rochefort, and referred to by 

 Mr. MacLeay in his paper on Urania and Mygale in the Transactions 

 of the Zoological Society 1831, where he observes, " It does not 

 change its colour ; nor, as far as I know, does it distend the throat 

 like the genus Anolis, neither are the toes as in that genus supplied 

 with oval discs for climbing, so that it is never seen on trees. Never-
