A NEW SNAKE AMD A NEW FROG FROM SIAM. 27? 



It is also a male, aiiil (litters from llie type in the lollowiiig 

 particulars : — 



Frontal shorter than the i)arietals, a siibocular between the onl 

 and 4th snpralabials, 7 snpralabials on the left side due to fusion of the 

 2nd and 3rd. Ventrals, 187; sub-caudals, hi). 



Colour, ijight brown above, the dorsal blotches hardly enlarged 

 at all. Below, uniform yellowish-white. 



Dentition. Maxillary, 11 ; palatine, 7; pterygoid, 11.' 



Total length, 670 mm., tail lUO. Author's number, 2.110. 



The type of Simotes lonijicaml'i is from the JIan-Soii mountains. 

 Tonkin. I have not been able to compare my specimens with it, but 

 in lepidosis they agrees so closely with the description, that thej' must 

 be referred to that species. Their colouration, however, is quite 

 distinctive, and entitles them to subspecilie rank. 



As Jlr. Boulenger's descrijitionS is probably not available to 

 many members of this Society, I have given a detailed account of my 

 own specimens. They will be presented to the British JIuseum. 



Eaua cubitalis. sp. nov. 



Bidi/nosis. Glandular latei-al fold narrow and prominent, toes 

 nearly entirely webbed, the tips with small but well developed discs. 

 The tibic-tarsal articulation reaches beyond the tip of the snout. 



Nearest perhaps to liana guentheri Boulengei-, from w liich it 

 differs in the position of the vomerine teeth, in the narrower and more 

 prominent glandular lateral fold, in the longer hind limb, and in the 

 larger terminal expansions to the toes. 



Description. Vomerine teeth in two obli(iiie groups between the 

 choanae and extending posteriorly slightly beyond them, the interval 

 between the groups etpial to their distance from the choanae. Head 

 longer than broad, snout as long as the orbit, obtusely pointed, canthus 

 rostralis distinct, loreal region oblicpie and concave, nostrils distinctly 

 nearer the tip of the snout than the eye. interorbital space ecjual to or 

 a little narrower than uj)per eyelid, tympanum very distinct, neaily 

 OS large as the eye. Fingers and toes moderate, first finger consider- 

 ably longer than fecond, toes nearly entirely webbed, tips of fingers
