SAURIA. 43 



We may make a fifth division, the 



Spheriodactyli, 



Of certain small Geckos, the ends of whose toes terminate in a 

 little pellet without folds, but always with retractile nails. 



When this pellet is double or emarginated in front, they are 

 closely allied to the simple Ptyodactyli. The species known are 

 from the Cape or from India: such is the 



G. porphyrS, Daud. Reddish-grey, marbled and dotted with 

 brown. (1) 

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

 all American: such is the 



G. sputateicr a bandcs, 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-co- 

 lour. Id., lb. f. 2. 

 Finally, there are some Saurians which, possessing all the cha- 

 racters 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 

 indented along the sides, constituting the 



Stenodactyli. 



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

 2.(2) Smooth, grey, sprinkled with whitish spots. 

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

 tail form the 



Gymnodactyli, Spix. 



Some of these are found in America with regular suites of small 

 tubercles. The Gymnodactylus geckoides, Spix, X, viii, 1, also ap- 

 pears to be one of them. 



Others again have their tail flattened horizontally, so as to resem- 

 ble the shape of a leaf. 



Phyllurus. 

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



(1) Daudin was mistaken in considering this Geckoas an American species, and 

 synonymous witli the mahouia. 



(2) Under the improper name o{ Jigame ponchie. It is reprochiced in tlie Siipp. 

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