alternating brown spots with light centra, which are charac- 
teristic of the principal form of Corallus Cookii. 
The question is, however, whether one ought to regard 
the two as distinct species judging only by the above-men- 
tioned characters, though they also have the same geographi- 
cal range. The only respect in which the two forms do not 
merge into each other is the number of the rows of scales. 
LINNA2US'S specimen, however, shows a trace of such an inter- 
mediate form, and it is probable that more such ones would 
be detected, was the material greater. I feel much inclined 
to put Corallus Cookii GRAY as a synonym to Boa Enydris 
LINNAUvs, and this form as a variety of Corallus hortulanus

The authors seem to have been doubtful about the iden- 
tification of this snake. NcCHLEGEL considers it to be a variety 
of Boa constrictor. DUMÉRIL and BIBRON reckoned one of 
LAURENTI'S species, Constrictor divinoloquus, though with ?, 
as a synonym to this; so also does BouLEnGErR. I am now 
able to prove that Linnauvs's Boa ophrias is the same as the 
Boa divinoloqua of the authors, which thus ought to be named 
Boa ophrias (L.).
