TRIMERESURUS STRIGATUS. 



" The shield forming the front part of the facial pit is separate from 

 the second upper labial. Supra-ciliary shield narrow ; no large shields 

 behind the rostral. The whole upper surface of the head is covered 

 with small, nearly smooth scales. Nine or ten upper labials, becoming 

 smaller hi size behind. Scales distinctly keeled, in twenty-one series. 

 Ventrals 136-142 ; sub-caudals 31-40. Tail but slightly prehensile, 

 terminating in a short cervical scale." (Giinther.) 



Sir Joseph Fayrer says — " A specimen in the Indian Museum 

 measures fourteen inches and a half; girth one inch and a quarter ; it 

 is brown, with a line of darker coloured, irregular vertebral spots. It 

 has a horseshoe-shaped whitish mark on the neck. There is a trian- 

 gular dark spot below the eye and loreal pit, and a dark brown band 

 leading from the eye to the neck. The lower jaw and belly marked with 

 black spots. The end of the tail terminates in a scale ; in young 

 specimens it is white." It is found on the Neilgherries, Anamallies, 

 and Deccan. It does not measure more than nineteen inches.

Gunther describes the snake as follows : — " Snout of moderate 

 length, broader than long, with the nose rather protruding. Rostral

 up into smaller shields. The anterior frontals short, transversely 

 produced, and tapering on the sides ; both taken together form a sort of 

 crescent. Posterior frontals large, somewhat pointed in front, and 

 rounded behind. Vertical and supra-ciliaries as usual in this genus ; 

 occipitals rather small, rounded. Five upper labials, a sixth and seventh 

 being confluent with the temporals ; the second is small, not entering 

 the margin of the facial pit ; the third enters the orbit. There is a
