LEPORIDZ—BIBLIOGRAPHICAL RESUME. 279 
1839.—Bachman, Journ. Acad. Nat. Sci. Phila., viii, 75-101. ZL. glacialis, = L. timidus var. areticus ; L. 
americanus ; L. sylvaticus ; L. aquaticus ; L. palustris; L,. Nuttalli, = L. sylvaticus var. Nuttalli ; 
L. nigricaudatus, = L. callotis; L. californicus ; L. Richardsoni, = L. californicus, and afterward 
so recognized by Bachman; L. Townsendi, = L. campestris, and later so recognized by Bachman ; 
L. artemisia, = L. sylvaticus var, Nuttalli ;—thirteen nominal species, three of which (L. Rich- 
ardsoni, L. Townsendi, and L. artemisia) are here first described. 
Bachman’s above-noticed papers are classic, and mark an important era of progress in 
the history of the American Leporida. In these papers, L. palustris, L. aquaticus, L. “ Nuttalli”, 
and L. “artemisia” are for the first time described ; L. campestris and L. sylvaticus receive their 
first distinctive names; and the confusion previously existing between these species and 
L. americanus is first cleared up. Two nominal species (L. Townsendi and L. Richardsoni) are 
added, but are afterward rescinded.
