~Conepatus mesoleucus venaticus~ Goldman

When Goldman (Jour. Mamm., 3:40, February 10, 1921) named _C. m.
venaticus_ from Arizona he did not mention material which Merriam
(Proc. Biol. Soc. Washington, 15:163, August 6, 1902) had recorded
from Ft. Verde, Arizona, under the name _Conepatus mesoleucus
mearnsi_. This material seems to be specimens in the American Museum
of Natural History of which the two oldest specimens are as follows:
No. 2486/1921, male, adult, from Box Canon, 20 mi. S Ft. Verde; No.
2487/1922, female, subadult, from Verde River, Arizona. Pertinent
measurements of these specimens are, respectively, as follows:
condylobasal length, 72.4, 68.8; zygomatic breadth, 50.0, 44.2; width
of braincase at constriction behind zygomata, 36.4, 33.8; mastoidal
breadth, 44.3, 38.4. Comparison of these measurements with those given
for _C. m. venaticus_ (Goldman, _loc. cit._) reveals that the
specimens concerned agree in narrowness of skull with _C. m.
venaticus_ (_C. m. mearnsi_ is relatively wider) and it is on this
basis that we refer the specimens to _Conepatus mesoleucus venaticus_.

~Urocyon cinereoargenteus costaricensis~ Goodwin

J. A. Allen (Bull. Amer. Mus. Nat. Hist., 20:48, February 29, 1904)
listed two specimens of gray fox from Pozo Azul, Costa Rica, as
_Urocyon guatemalae_. Goodwin, in his "Mammals of Costa Rica" (Bull.
Amer. Mus. Nat. Hist., 87(5):271-474, December 31, 1946) did not
mention any material from Pozo
