1907. _Sylvilagus audubonii neomexicanus_ Nelson, Proc. Biol. Soc.
Washington, 20:83, July 22.
Nelson (N. Amer. Fauna, 29:230, August 31, 1909) listed under
_Sylvilagus audubonii cedrophilus_ Nelson an adult female, skin with
skull (U.S. Nat. Mus., Biol. Surv. Coll., No. 108698) from fifteen miles
south of Alpine, Texas. Nelson (_loc. cit._) remarked that the
"bleached" color of the back and the great lateral breadth of the
tympanic bullae of No. 108698 were peculiarities not possessed by any
other specimen examined. Geographically, the locality of capture is far
south of other known occurrences of _S. a. cedrophilus_ and
approximately on the boundary separating the range of _S. a. minor_ from
that of _S. a. neomexicanus_. The large size, which may have induced
Nelson to refer the specimen to _S. a. cedrophilus_, is not surprising
considering that the individual is a female and fully adult. A
combination of new and old fur on the upper parts presents a pattern
that might be duplicated in other specimens of _S. a. neomexicanus_. The
lateral inflation of the tympanic bullae can be interpreted as
intergradation with the geographically adjacent _S. a. minor_ to the
south; _S. a. minor_ has large bullae. There are no features otherwise
which suggest that the specimen is anything other than _Sylvilagus
audubonii neomexicanus_ and we refer it to that subspecies.
