GYMNODACTYLUS FR^NATUS. 113 



Gymnodactylus triedrus. 



Back granular, studded all over with small trihedral tubercles ; (tail (reproduced) uniformly 

 granular above, with small irregular scales beneath, rather thick, tapering). Ten upper and 

 nine lower labials ; nostril immediately behind the rostral ; prseanal or femoral pores none 

 (in the single specimen observed) ; scales of the middle of the belly in about thirty longi- 

 tudinal series. Limbs and toes moderately slender. The two terminal joints of the fingers 

 and toes are compressed, not very distinct from the basal joints, which are provided Avith 

 transverse disks below. Uniform brown ; tail with four indistinct rings of irregular Avhitish 

 spots. 



Ceylon. The single specimen observed is in the British Museum ; it is nearly 4 inches 

 long, and not in a very good state of preservation. 



Gymnodactylus pulchellus. 



Cyrtodactylus pulchellus, Gray, Phil. Mag. ii. p. 56, and Ind. ZooL, Rept. tab. 

 Gymnodactylus pulchellus, Wagl. Amph. p. 144. Cantor, Catal. Mai. Rept. p. 25. 



Body finely granular, with numerous conical (in old specimens, three-sided) tubercles of 

 moderate size. Eleven or twelve upper and lower labials ; the median lower labial is 

 triangular, produced backwards between the anterior chin-shields, which are rather elongate. 

 The scales of the middle of the belly form twenty-six longitudinal series ; the series of 

 femoral pores extends along nearly the whole length of the thigh, and is bent forwards in 

 the middle of the preeanal region, where it is continued into a short longitudinal groove in 

 the skin ; each half of the series is composed of nineteen pores. Subcaudals enlarged. The 

 two terminal joints of the fingers and toes are much compressed, and very distinct from the 

 basal joints, which are provided with a series of transverse disks. Bro\vnish yellow: the 

 nape of the neck and the back with six broad browTiish-black cross bands edged with 

 yellow ; the two anterior bands crescent-shaped. Tail with eight or nine rings of the same 

 colour, but without yellow margin. 



This beautiful species is found in elevated parts near Pinang and Singapore, and attains 

 to a length of 10 inches. Cantor says that its habits are similar to those of other Geckos ; 

 it bites fiercely in defence ; in captivity it refuses insects *. The integuments, when about 

 being renewed, are torn off piecemeal by the teeth and devoured. A single egg deposited 

 was of a spherical form, about half an inch in diameter, of a whitish-yellow colour. 



Gymnodactylus fr^natus. (Plate XII. fig. D.) 



Body granular, with six or eight series of very small tubercles ; tail uniformly granular, 

 * I should recommend as food other small Geckos or lizards.
