38 REPTILES. 



allied to the simple Ptyodactyli. The species known are from the Cape 

 or from India: such is the 



Gc porphyre, Daud. Reddish-grey, marbled and dotted with 

 brown*. 

 Most generally the pellet is simple and round. The species are all 

 American : such is the 



G. sputateur a bandes, Lacep. Rept. I, pi. xxviii, f. 1. A small 



species, prettily marked with transverse brown bands laid on a red 



ground: common in the houses of St. Domingo, where it is also called 



the Mabouia. There is a neighbouring species in the same island, 



but which is of a uniform ash-colour, Id. lb. f. 2. 



Finally, there are some Saurians which, possessing all the characters 



of Geckos, have no enlargement of the toes. Their five nails, however, 



are retractile. 



Some of them have a round tail, and the toes striate beneath and in- 

 dented along the sides, constituting the 



Stenodactyli. 



There is one in Egypt, Sten. guttatus, Egyp. Rept. pi. V. f. 2 f. 

 Smooth, grey, sprinkled with whitish spots. 

 Others have naked and slender toes : those which have a round tail 

 form the 



Gymnodactyli of Spix. 



Some of these are found in America, with regular suites of small tu- 

 bercles. The Gymnodactylus geckoides, Spix, X, viii, 1, also appears to 

 be one of them. 



Others again having their tail flattened horizontally, so as to resemble 

 the shape of a leaf, I have given the name of 



Phyllurus. 

 Only one species is yet known, and that is from New Holland, 

 Stellio phyllurus, Schn. ; Lacerta plaiura, White, New South Wales, 

 p. 24G, f. 2 \. Grey, marbled with brown above; completely covered 

 with small pointed tubercles. 

 We are compelled to establish a fifth Family, 



FAMILY V. 



CHAM^LEONIANS, 



For the single genus, 



Cham^leo §. 

 Or the Chameleons, which is very distinct from all other Saurian genera, 

 and is not even easily introduced into their series. 



* Daudin was mistaken in considering this Gecko as an American species, and 

 synonymous with mabouia. 



f Under the improper name of Agame ponclue. It is reproduced in the Supp. 

 pi. 1, f. 2; and a neighbouring species, f. 4. 



J Referred, for some unknown reason, by Daudin to Stellio. 



§ From Chamaileon, (Little Lion), the Grecian name of this animal. Aristotle, 

 who uses it, has also given a perfect description of it. Hist. Ann. Lib. II, cap. xi.
