yellow collar ; the neck behind this collar is brilliant vermilion

Tropidonotuschrysargus, Blgr. Cat. Snakes, i. p. 258. 



This beautiful snake appears to be a mountain form in the 

 Malay Peninsula. Cantor got one individual on Penang Hill, and 

 Mr. L. Wray, Dr. Hanitsch, and myself have in different years 

 obtiiined it in the Larut Hills, Perak, from 3000 to 3400 feet 

 above the sea. 



Habits. Cantor says : " Like most of the Asiatic species of this 

 genus, the present is of fierce habits. It twice unprovokedly bit 

 a woodcutter who happened to pass it. The bite, of course, was 

 productive of no consequences except a slight momentary pain." 



Colour (ia life). A specimen 310 mm. in length was above 

 very dark rich olive-brown, with a bright yellow collar-mark 

 forming an acute backward-pointing angle on the neck ; the skin 

 between the scales is brick-red, and shows as fine red reticulations 

 on the anterior part of the body. Labials bright yellow, upper 

 outlined in black. Below, head and neck bright yellow, remainder 

 greyish buff, with small black spots, and a very distinct black 

 spot on the side of each ventral and pair of subcaudal scales. 



A specimen 760 mm. in length differed in having no collar- 

 mark and the red reticulations showing only on the neck, also other 

 markings which were hardly distinguishable on the smaller 

 specimen here siiow, viz. numerous narrow black transverse lines, 

 each interrupted by a dorso-lateral series of dull orange-brown 

 spots. The lower parts of the sides are iridescent crimson, 

 speckled with black, and the belly is yellowish, only shading to 

 greyish buff posteriorly. 



The whole lower surface is highly iridescent, with purplish 

 shades. The eye is large and noticeable. Iris, very narrow 

 golden ring round pupil, remainder rich red-brown, with a redder 

 patch above the pupil. 



Hah. Eastern Himalayas, Assam, Burma, South China, Malay 

 Peninsula, Sumatra, Nias, Java, Borneo, Palawan, Balabac, Sipora 

 (Mentawei Islands).
