LEPORIDiE— BIBLIOGRAPHICAL RESUME. 279 



1830.— Bachman, Journ. Acad. Nat. Sci. Pbila., viii, 75-101. L. glacialis,= L.limidus var. arcticus ; L. 

 americanus ; h. sylvaticus ; L. aquaticus j L. palustris ; L. Nuttalli, = L. sylvaticus var. Nuitalli ; 

 L. nigricaudatus, = L. callotis; L. californicus ; L. Richardsoni, = L. californicus, and afterward 

 so recognized by Bachman; L. Townsendi, = L. campestris, a,ud later so recognized by Bacliman ; 

 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 Leporidas. In these papers, L. jialustris, 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 added, but are afterward rescinded.
