I have nothing to add to Mr. Boulenger's excellent descrip- 

 tions (one of which I quote in full from the Fauna of the Malay 

 Peninsula), except to say that the U-shaped band on the back of 

 the head may be broken up into a series of large spots. 



"Ear-opening subtriangular, half the diameter of the eye. 

 Limbs moderate ; toes short, scarcely depressed at the base, the 

 plates under the basal phalanx small, much narrower than the 

 digit, roundish, convex. Head granular, with minute tubercles 

 on the occiput ; rostal with median cleft above, entering the 

 nostril ; 9 upper and 7 or 8 lower labials ; symphysial triangular ; 

 four pairs of chin-shields, the median largest and forming a suture 

 behind the symphysial. Body and Hmbs granulate above, with 

 numerous small, round, keeled tubercles; a feeble fold along the 

 side; ventral scales small; imbricate about 45 in a transverse 

 series. Males with a angular series of 7 or 8 praeanal pores ; no 

 femoral pores. Tail covered with small scales. Pale grey above, 

 with blackish-brown markings edged with whitish, viz. several 

 spots on the tip of the head , a U-shaped band from eye to eye 

 across the nape, two series of large spots on the back, and a series 

 of smaller spots along each side, lower parts whitish. From snout 

 to vent 64 millim ; tail 64." (Boulenger). 



G. peguensis seems to me to be most nearly related to G. 

 variegatus (Blyth) from the Amherst district of Tenasserim. 

 Males of the two species are easily recognized by the number and 

 arrangement of the pores ; females can be distinguished only by 

 slight differences in colouration and in the conformation of the 

 head and by the smaller and more numerous ventral scales of G. 

 peguensis. From G. ruhidus (Blyth), with which Boulenger com- 

 pares his species, it is distinguished by its conspicuous coloura- 

 tion, its much stouter habit, the form and lepidosis of its tail and 

 other important characters. Laidlaw has recorded G. peguensis 

 from the central region of the Siamese Malay States and his 

 record is confirmed by Boulenger. In Burma it has only been 

 found in the hilly districts of Pegu and Arrakan. In the Dawna 

 range in the interior of the Amherst district of Tenasserim, it is 

 apparently replaced by G. variegatus.
