LEPORIDiE— BIRLIOGRAPIIICAL RESUME. 277 



sissippi. Two (L. sylvaticus and L. america?ius) occur in Southern New 

 England, over large portions of the Middle States, and over the northern por- 

 tion of the tier of States adjoining the Great Lakes and the contiguous por- 

 tions of Canada. Two (L. sylvaticus and L. palustris) are found in the lower 

 portions of the South Atlantic States, and three (L. sylvaticus, L. palustris, 

 and L. aquaticus) over most of the lowlands of the Gulf States. 



The great interior arid plateau is the most prolific in species, four being 

 here found. Th ree of these (L. sylvaticus var. Nuttalli, L. eampestris, and L.cal- 

 lotis) range over most of the region hetween the eastern edge of the Great Plains 

 and the Pacific slope, and the fourth {L. americanus var. Bairdii) is met with 

 throughout the wooded portions of the Rocky Mountains, southward, at least, 

 to New Mexico. Three species (L. sylvaticus var. Auduboni, L. californicus, 

 and L. Trowbridgei) are also found on the Pacific slope from Southern Ore- 

 gon to the southern point of Lower California. Two species (L. callotis var. 

 texianus and L. sylvaticus var. Nuttalli) range over the dry interior of Mexico, 

 and three species (L. sylvaticus var. sylvaticus, L. palustris, and L. aquaticus) 

 are found in Eastern and Southeastern Mexico. These species also probably 

 extend to the northern portions of the Central American States, where they 

 reach the habitat of L. brasiliensis, which becomes the sole representative 

 of the family thence southward. 



IV. BIBLIOGRAPHICAL RESUME. 



The more important notices of the American Leporida are those enu- 

 merated below. The synonymy of the species and varieties will be found 

 more fully discussed later. 



1766.— Linnaeus, Syst. Nat., 12th ed., i, pp. 77, 78. Two species are given, Lcpus timidus and L. brasili- 

 ensis, the latter only as American. 



1 772.— Barrington, Phil. Trans., lxii, 11. " Hudson's Bay Quadruped ", => L. americanus var. americanus. 



1772.— Forster, Phil. Trans., lxii, 376. American Hare, = L. americanus var. americanus, with vague 

 allusions to L. sylvaticus. 



1777.— Erxleben, Syst. Reg. Auiin., 325, 330. L. timidus and L. americanus. The latter is based on 

 Kalm's Haase (Reise Niird. Am., iii, 349), Barrington's "Hudson' Bay Quadruped" (Phil. 

 Trans., lxii, 11), and Forster's "American Hare " (Phil. Trans., lxii, 376), and hence entirely on 

 unrnrestionable references to the L. americanus of recent authors, or the Northern Varying 

 Hare. 



1778.— Pallas, Nov. sp. Glires, 30. Two strictly American species,— Lcpus hudsonius ( = L. americanus) 

 and L. iapeti (= brasiliensis) ; also L. variabilis, = L. timidus. 



17§0. — Fabricius, Faun. Grceul., p. 25. Lepus timidus, = L. timidus var. arcticus. 



1781 and 1781.— Pennant, Hist. Quad., no. 243,and Arct.Zool., i,95. American Hare = L. americanus, 

 with vague allusions to L. sylvaticus. (These editions I have not seen.) 



17§4.— Schbpf, Der Naturforscher, 20. Stiick, Halle, 1784. Deruord-amerikanische Haase. An ex- 

 colknt description of L. sylvaticus. (See Baird, Mam. N. Amer.. pp. 599, COO.)
