NEW LIZARDS AND A NEW SNAKE FROM SIAM. 47 



transversely across the body. Tliey are more or less imlented mesially, 

 and confluent witii a smaller spot on either side. Between each spot 

 are 3 indistinct cross bands, produced by a black edging to some of 

 the scales. Below yellowish-white ( coral red in life ) with black 

 quadrilateral spots on either side. Head with dark brown, light-edged 

 marks of the /S'u/iofes pattern, namely ; a broad crescent on the snout, 

 passing through the eyes on to the lips, an oval .spot on the top of 

 the iiead, confluent or not with an oblique band passing on to the 

 sides of the throat, and with the apex of a heart-shaped mark on 

 the nape. 



Total length 380 mm., tail 70. 



Described from 3 specimens taken at Hup Bon, E. of Sriracha 

 S. E. Siam, by Mr. P. A. R. Barron, to whom I liave dedicated the 

 species. 



This snake lias been found also at Sriracha, at Koh Lam, 

 a small island near, and at Muak L?k ( alt. 900 ft. ) in the Djng R^k 

 range, E. Siam. Tlie specimen from Muak L ik has 100 ventrals, two 

 specimens from Sriracha 33 and 3-t SLibsauilals respectively, whilst a 

 third has only 135 ventrals. The formula will therefore now read ; 

 ventrals 135-160, sub-caudals 32-'l-l. One specimen from Sriracha 

 liae 8 supra-labials on each side with the 4th and 5th entering the 

 eye. Three more have 7 on one side, 8 on the other. In one Sriracha 

 specimen there are no large dorsal spots on the anterior three-quarters 

 of the body. 



Types of all the above named species are being deposited in the 

 British Museum with Mr. G. A. Boulengei', to whom 1 am indebted 

 for confirming my belief that they were new to science.
