Described by LInNaus in Mus. Ad. Frid. IT, p. 48.

Boa Enydris. 
Described by LIinnzus in Syst. Nat. Ed. X, p. 215, Ed. XI, p. 374. 
Syn. according to BourL. Cat. Sn. I, p. 101, Corallus hortulanus (L;) 
GRAY. 
Most authors regard this Linnean snake as a form of- 
LINN2aUus's Boa hortulana. LIiNnavs does not give any diffe- 
rences between these types, except the colour and the number 
of the caudal and ventral shields, which are more numerous 
in Boa hortulana (290 + 128: in Boa Enydris 270 + 105). On 
the ground of the same characters, GRAY, however, in The Zoolo- 
gical Miscellany, p. 42, in 1842 introduces a new species, nearly 
allied to Boa hortulana, to which he gives the name Corallus 
Cooktii. BoULENGER maintains this species in his catalogue, 
distinguvishing it from Cor. hortulanus by the number of the 
rows of scales, and by that of the ventral and caudal shields. 
The formula of C. Cookii is: Sq. 39—47, V. 253—285, C. 101— 
118, and of C. hortulanus: Sq. 51—59, V. 270—299, C.: 108— 
128. Otherwise the two descriptions agree completely. As 
to the colour, it seems to vary considerably; for which reason 
no constant character is established in this respect. 
If, on the ground of these characters, the two forms be 
regarded as distinct species, LINNAavs's Boa Enydris ought to 
belong to Corallus Cookii, which then might be named Corallus 
enydris, to which this snake in every particular seems to 
correspond. The dark colour above, which is said to exist 
in this species, has completely disappeared on the Linnean 
specimen. On the sides of the body, however, there are some
