5Ö COPniAS WAGLERI. 



Another snake, somewhat resembling this Celebean va- 

 riety, was captured in Sumatra by S. Muller. It is a spe- 

 cimen of 62 cm., which shows the same coloration of the 

 cross-bands, only with the white color somewhat less de- 

 veloped. The color of the back is also blue passing into 

 green and yellow , but the scales are all edged with black. 

 The cross-bands on the tail do not reach the end, which 

 is of a reddish color. 



All the here described specimens agree with the typical 

 specimens of B. Wagleri in having the second upper labial 

 shield separated from the facial pit , in having strongly 

 keeled scales on the top and the under surface of the 

 head, and having 135 — 150 ventral shields. The number 

 of scales in a transverse series may vary from 21 — 25. 



They must all be regarded as specimens of Bothrops 

 Wagleri. 



This is not the case with the Coluber sumatranus Raffles. 



In the » Description of a Zoological collection made in 

 Sumatra" by Sir Thomas Stamford Raffles ^) we meet with 

 the description of a pitviper „which has some resemblance 

 with C. gramineus, but is larger and much more venomous, 

 being particularly distinguished by having two fangs of 

 extraordinary length." 



Sir Raffles proposes the name of Coluber sumatranus 

 for this species, which distinguishes itself from the other 

 pitvipers by having 184 ventral and 69 caudal shields. 

 Other characteristicals are : two large plates above each eye , 

 and a general green color, the body being encircled with 

 several irregular black rings and the tail being of a red- 

 dish color, whilst each scale of the body is edged with 

 black. 



This Coluher sumatranus was about 4 or 5 feet in length 

 and rather thick , and had two fangs of about half an 

 inch in length, white and slender and curved backwards. 



This specimen probably got lost and the above men-
