LEPORID—BIBLIOGRAPHICAL RESUME. 277 
sissippl. Two (L. sylvaticus and L. americanus) 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 (LZ. sylvaticus and L. palustris) are found in the lower 
portions of the South Atlantic States, and three (L. sylvaticus, L. palustris, 
and L. aqguaticus) over most of the lowlands of the Gulf States. 
The great interior arid plateau is the most prolific in species, four being 
here found. Three of these (L. sylvaticus var. Nuttall, L.campestris,and L.cal- 
lotis) range over most of the region between the eastern edge of the Great Plains 
and the Pacific slope, and the fourth (Z. americanus var. Bairdit) 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 LL. 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 Leporide are those enu- 
merated below. The synonymy of the species and varieties will be found 
more fully discussed later. 
1766.—Linnzus, Syst. Nat., 12th ed.,i, pp. 77,78. Two species are given, Lepus timidus and L. brasili- 
ensis, the latter only as American. 
4772.—Barrington, Phil. Trans., ]xii, 11. “ Hudson’s Bay Quadruped”, = L. americanus var. americanus. 
1772.—Forster, Phil. Trans., ]xii, 376. American Hare, = L. americanus var. americanus, with vague 
allusions to ZL, sylvaticus. 
1777.—Erxleben, Syst. Reg. Anim., 325, 330. ZL. timidus and L. americanus. The latter is based on 
Kalm’s Haase (Reise Nord. Am., iii, 349), Barrington’s “ Hudson’ Bay Quadruped” (Phil. 
Trans., Ixii, 11), and Forster’s “American Hare” (Phil. Trans., Ixii, 376), and hence entirely on 
unquestionable references to the ZL. americanus of recent authors, or the Northern Varying 
Hare. 
1778.— Pallas, Nov. sp. Glires, 30. Two strictly American species,—Lepus hudsonius (= L. americanus) 
and ZL. tapeti (= brasiliensis); also L. variabilis, = L. timidus. 
41780.—Fabricius, Faun. Greenl., p. 25. Lepus timidus, = L. timidus var. areticus. 
B7SH and 1784.—Pennant, Hist. Quad., no. 243, and Arct. Zool.,i,95. American Hare = LZ. americanus, 
with vague allusions to L. sylvaticus. (These editions I have not seen.) 
1784.—Schépf, Der Naturforscher, 20. Stiick, Halle, 1784. Dernord-amerikanische Haase. An ex- 
collent description of L. sylvaticus. (See Baird, Mam. N. Amer., pp. 599, 600.)
