40 REPTILIA. 



with simple round tubercles, which are more salient on the 

 flanks,— G. xpjpllacus, Nob. Egypt., Rept., pi. v, f. 7.(1) 

 The nails arc only deficient in the four thumbs of the greater num* 

 her of the platydactile Geckos. They have a range of pores before 

 the anus.(2) Such are. 



Gecko, Lacep. I, xxix; Stellio Gecko, Schneid.j Le Gecko a 

 gouttelettes, Daud.; Seb. I, cviii, the whole plate. Rounded, 

 slightly salient tubercles over the upper surface of the body, 

 whose red ground is sprinkled with round white spots; tail fur- 

 nished beneath with square and imbricated scales. Seba says 

 it is from Ceylon, and pretends that it is to this identical spe- 

 cies that the name of Gecko is applied in imitation of its cry; 

 but long before him it was attributed by Bontius to a species 

 of Java. It is probable that the cry and the name are common 

 to several species. We have ascertained that this one is found 

 throughout the Archipelago of India. 



Lac, villatu, Gm.; Le Gecko a bandes; Lizard Pandang, at 

 Amboina; Daud. IV, 1. Brown; a white band on the back 

 which bifurcates on the head and on the root of the tail; tail 

 annulated with white. From the East Indies: found at Am- 

 boina on the branches of the shrub called the Pandang.(3) 

 There are some of these four-nailed Platydactyli whose body is 

 edged with a horizontal membrane, and which have palmated feet. 

 One of the most remarkable is 



Luc. homuloccphala, Crevett., Soc. of Nat. of Berlin, 1809, 

 pi. viii, the sides of whose head and body are augmented by a 

 broad membrane, which is scalloped into festoons on the sides 

 of the tail. Its feet are palmated. Found in Java, in Bengal.(4) 



There is another species in India with a bordered head and 

 body, and palmated feet, but in which the festoons on the tail, 

 and the pores near the anus, are deficient,' — Pteropleura Hors- 

 fieldiiy Gray, Zool. Jour. No. X, p. 222. 



Finally, some l^latydactyli have no nails to all their toes. 



There is a smooth species with palmated feet in France, — .^.

 In a second subdivision of the Geckos, which I call the 



(1) Tills fig', entitled Vur. du Gir.lio annuluirc, has too many nails.

(3) N.IJ. iJaiulin cn'oneoiisly gives nails to the thumbs of these two Geckos. 



(4) 'I'liis hopflered Platydaclylus forms the genus Pfi/rhozoon of Vh/Angcr- M. 

 Gray also separates his 1'tkiioim.i;iiua from them on aceoiint of the absence of the 

 pores.
