A Synopsis of the North American Lagomorpha

A Synopsis of the North American Lagomorpha is by E. Raymond Hall of the University of Kansas. The contents list covers, among others, the order Lagomorpha, meaning hares, rabbits and pikas, the family Ochotonidae, pikas, and the family Leporidae, rabbits and hares.

The writer says the skulls are necessary for the identification of some species of the genus Sylvilagus, while the skins are essential for the species of the genus Lepus in central Mexico and in the Great Basin of the western United States. The writer says it has been impossible to construct a key based on external characters only or on cranial features only. The writer hopes the key and the accompanying account will aid workers who need to identify kinds of lagomorphs and to know about their geographic distribution. An entry for the New England Cottontail, Sylvilagus transitionalis (Bangs), gives a type from Liberty Hill, New London County, Connecticut, and lists marginal records for Vermont, Maine and New York.
