Though LInNAZvs at a later period follows HASSELQVIST 
and pronounces this snake to be a distinct species, he at 
first regarded it as a specimen of Col. vipera deformed by 
human art, which appears from the following remark in 
the description of Col. vipera in Mus. Ad. Frid. »Vipera 
cornuta, ab HASsELQVIST in Act. Ups. 1750 p. 27 descripta, 
est heec ipsa species, Arabum astuta arte deformata, intrusis 
2 unguibus volucris alicujus per caput, quwibus Auctor seduc- 
tus fuit.>
