[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. t I have two specimens of Enhydrina 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 the tail; the other specimen has the short granular head of E. valakadyen, with forty-nine rows of scales round the neck 2 inches behind the head. TRIMERESURUS ERYTHRURUS, Cantor; Gthr. I. c. p. 386. Sulsaugur, Assam. TRIMERESURUS CARINATUS, Gray ; Gthr. I. c. p. 386. Garo Hills. 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.

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.
