from New Caledonia, and, if so, furnishing a link, though a very 
imperfect one, between the disconnected halves of the family.

The Pythonidse, comprising the Pock Snakes, Pythons, and 
Boas, are confined to the tropics, with the exception of one 
species in California. They are very abundant in the Neotropical 
region, where nearly half the known species occur ; the Austra- 
lian region comes next, while the Oriental is the least prolific in 
these large serpents. The genera which have been described 
are very numerous, but they are by no means well defined. 
The following are the most important : — 
Python is confined to the Oriental region ; Morelia, Liasis, and 
Nardoa are Australian and Papuan; Enygrus is found in the 
Moluccas, New Guinea and the Fiji Islands ; Hortulia is African ; 
Sanzinia is peculiar to Madagascar; Boa , Epicmtes, Cor alius, 
Ungalia, and Eunectes are Tropical American; Chilabothrus is 
peculiar to Jamaica and Mexico ; and Lichanotus to California. 
An extinct species belonging to this family has been found 
in the Brown -coal formation of Germany, of Miocene age.
