816 EEPTILIA. 



there are four loreals on the right side, the supplementary shield being evidently a 

 separated portion of the uppermost loreal. This specimen measures 51*50 inches 

 in length, of which the tail is 14 inches, and it has 196 ventrals and 127 sub- 

 caudals. 



In the Mandalay snake there are nine upper labials, the fifth and sixth entering 

 the orbit. In all other particulars, these specimens agree with Indian examples of 

 the species.

The following specimens from the parallel valleys of Sanda and Hotha in Yunnan 

 agree with the generality of the examples of this snake which have come under 

 my observation, except in the greater number of the ventral and sub-caudal shields, 

 but even the highest number of the ventral shields in these Yunnan snakes is 

 exceeded by a specimen of the species from Darjeeling in which they are as 

 many as 187.

This species ranges eastwards from the Sikkim Himalaya through Assam to 

 Upper Burma, Western Yunnan, and Southern China and Siam, and through Arracan 

 and the Malayan Peninsula to Sumatra and Java. 



The snake from Ceylon referred by Blyth to this specimen is apparently an 

 example of P. mucosus^ and Ferguson states that P. horros is never found in that 

 island.
