194 DR. J. ANDERSON ON INDIAN REPTILES. [Feb. 21, 



they at once strike one as characteristic features of the Snake ; 

 these, combined with the characters given in the above diagnosis, 

 are sufficient to separate them. 



I have two specimens of Enlujdrina from the Botanical Gardens, — 

 one with the elongate head and rather long gape of E. schistosa, 

 with the upper surface of the head granular, with forty-seven rows 

 of scales 2 inches behind the neck, the head being one-third the 

 length of tbe tail; the other specimen has the short granular bead 

 of E. valakadyen, with forty-nine rows of scales round the neck 

 2 inches behind the head.

Trimeresurus gramineus, Shaw; Gthr. I. c. p. 385. 



Scales in twenty-one series, those on the head smooth or faintly 

 keeled ; an azygos shield between the supranasals. Bright yellow- 

 green, darkest on the back, and greenish yellow on the head ; under 

 surface bright greenish yellow, with a faint greenish-yellow line 

 along the outer line of scales, and continued on to the head below 

 the eye ; tip of tail brick-brown.

In the last two specimens the lines along the side are very bright, 

 tbe lower one bright brick-colour, involving one-half of the first 

 body-scale, the other pure white, covering tbe other half, and tbe 

 half of the second body-scale, becoming narrow on the tail, and 

 disappearing about its middle, or, as in the case of the young one, 

 becoming broken up into a series of red and white lateral spots ; 

 upper surface of the tail brick-red. 



This appears to be a common Snake in the tropical valleys below 

 Darjeeling, where it is usually found at an elevation of 2000 feet.

Theobald's T. andersoni was founded on a solitary specimen from 

 an unknown locality, with twenty-five rows of keeled scales and an 

 azygos shield between the supranasals. In specimens, however, of 

 this species from Hotha (4500 feet), Western Yunan, the azygos is 

 sometimes present, and absent in others, and the scales are in
