COPIIIAS WAGLERC. 49 



line. The number of cross-bands on the body is 34 to 35, 

 whilst there are still some similar bands to be observed 

 on the root of the tail. The end of the tail is blackish. 

 The yellow color of the scales shows the highest develop- 

 ment on the back ; on the sides of the body the scales are 

 almost pure blue, except the last row of scales, which is 

 formed by yellow scales with a blue margin. 



The scales of the body are somewhat larger than the 

 scales of the typical specimens of B. Wagleri of the same 

 length, and the keels much more developed. 



Though this specimen differs in many points from the 

 other specimens of B. Wagleri •, I do not think it reasona- 

 ble to base a new species on it, and prefer to regard it 

 as a blue colored variety. 



Of another variety 2 specimens of nearly the same length 

 (64 cm.) and coloration were captured in Celebes. The 

 color of the back is a marine-blue passing into green on 

 the sides, and into yellow on the ventralia. The scales 

 are not provided with black edges but uniformly colored. 

 The head is entirely blue with an indication of a paler 

 line on the canthus rostralis and behind the eye. Along 

 the sides there is a series of cross-bands (25 on the right 

 side) placed alternatively on each side but sometimes flow- 

 ing together on the back. These cross-bands are formed 

 by a white and a black line running side by side. In 

 most of them the white line is the foremost. The black 

 color of the cross-bands sometimes reaches the ventralia 

 where it forms a black spot. The tail is also provided 

 with black cross-bands , flowing together on the back ; in 

 one of these two specimens these cross-bands, 11 in num- 

 ber, are present till the end of the tail, in the other spe- 

 cimen they do not reach so far, and the end of the tail 

 is of a reddish color. 



As these two specimens were the only ones we got from 

 Celebes , and were collected at the same place , I cannot make 

 out whether this variety is a common one in that island, 

 or whether it ought to be considered as an exception.
