74 VIPERAD A. 
The Black Viper, of which I give a figure, drawn from 
a very fine living specimen, now before me, obtained, and 
obligingly lent me, by Mr. Combe, is the var. 6 of Mr. 
# CO Gow 
a el 1Nhaeee ti 
Jenyns. It has been figured, though but badly, and 
described by Dr. Leach, in his Zoological Miscellany. It 
is evidently a variety only of the present species, and is of 
a fine rich black colour, excepting under the jaw and 
throat, which is of a dirty white; the usual markings of 
the species may be seen, in particular lights, of a more 
- 
intense black than the ground colour.
