CHAPTER XII
DISTRIBUTION
Representatives of the order Ophidia are found over the whole world, with the exception of Iceland, Ireland, and New Zealand, between the Northern limit of 67° in Europe (Vipera berus), 60° in Asia (Vipera berus), and 52° in America (Tropidonotus ordinatus), and the Southern limit of 44° (Philodryas schotti). The highest altitudes reached by them are 14,000 feet in the Himalayas (Tropidonotus baileyi), 9,700 feet in the Alps (Vipera aspis), and 9,000 feet in the Andes (Liophis albiventris). They are most numerous between the tropics, and the number of species gradually diminishes to the North and South.
For the purpose of showing the distribution of the principal groups, we will follow the divisions into families and subfamilies enumerated above (p. [4]).
Typhlopidæ.—S.E. Europe, S. Asia, Africa, Australia (exclusive of Tasmania), C. and S. America, and W. Indies.
Glauconiidæ.—S. Asia (as far E. as Sind), Africa (exclusive of Madagascar), C. America (extending into the S. parts of N. America), S. America.
Pythoninæ.—S. Asia, Africa (exclusive of Madagascar), Australia (exclusive of Tasmania), C. America.
