44 COPHIAS WAGLERI.

 Schlegeli) ^), and 



Tropidolaemus formosus Bleeker. ^) 



These two new species , created by Dr. Bleeker and men- 

 tioned as such in several lists of the fauna of the Malayan 

 islands, were never described by the author himself, who 

 referred as to the description , to his great work on East- 

 Indian Reptiles to be published afterwards. This work ha- 

 ving never appeared , and the typical specimens , both of Tr. 

 Schlegeli and Tr. formosus , being in the possession of the Ley- 

 den Museum , I intended to give their description after a 

 careful examination of the typical specimens. I therefore 

 compared them with the specimens of Bothrops Wagleri 

 in our collection , and though the result of this exami- 

 nation is a negative one as to the identity of the new 

 species , I found so great a difference between the various 

 specimens of B. Wagleri (28 in number) , that I suppose it 

 will not be without advantage for science, when I give 

 here the description of some of the various forms of B. 

 Wagleri of different ages , found in different parts of the 

 Malayan Archipelago. 



The most common coloration of the specimens in our 

 collection is that already described by Giiuther 1. c. as the 

 coloration of the halfgrown- and the adult state. 



The color of the body is black and yellow or greenish- 

 yellow, with a great number of yellow cross-bands. The 

 yellow or greenish-yellow scales are all edged with black , 

 with exception of those scales which form the cross-bands. 

 This black on the scales increases with age so that in the 

 largest forms the yellow color is reduced to a round spot 

 on the black scale. 



The head is covered with small scales of a black or yel- 

 low or greenish-yellow color. The colored scales on the 

 head never have black edges. The cantbus rostralis is co-
