Washington, 20:83, July 22.
Nelson (N. Amer. Fauna, 29:230, August 31, 1909) listed, without
comment, under _Sylvilagus audubonii cedrophilus_ Nelson, a skin with
skull inside (Amer. Mus. Nat. Hist., 5419, [female] adult or sub-adult)
from San Diego, Chihuahua, Mexico. We locate San Diego approximately 230
miles south and 60 miles east of El Paso, Texas. Thus, the specimen is
from near the center of the geographic range of _Sylvilagus audubonii
minor_. With the permission of Mr. G.G. Goodwin of the American Museum
of Natural History we removed the skull. It differs in no essential
features from those of other specimens of _S. a. minor_. For example, of
specimens in the United States National Museum, Biological Surveys
Collection, a female (No. 132002) from Guzman in Chihuahua, and a male
(No. 51020) from Santa Rosalia in the same state, are almost
indistinguishable from the San Diegan specimen. The specimen is without
external measurements but the length of the hind foot and length of ear
from the notch in the dry state (80 and 57, respectively) agree with the
corresponding measurements of _S. a. minor_. Color of the skin furnishes
no diagnostic character as between _S. a. minor_ and _S. a.
cedrophilus_. We identify the specimen from San Diego as _Sylvilagus
audubonii minor_.
