~Blarina brevicauda minima~ Lowery
Bailey (N. Amer. Fauna, 25:207, October 24, 1905) identified as
_Blarina brevicauda carolinensis_ one specimen from Joaquin and two
specimens from Big Thicket, 8 mi. NE Sour Lake, both localities in
eastern Texas. Strecker and Williams (Jour. Mamm., 10:259, August 10,
1929) later recorded the specimens again under the same name. The
subsequent naming of _B. b. plumbea_ from Aransas National Wildlife
Refuge, Aransas County, Texas (Davis, Jour. Mamm., 22(3):317, August
14, 1941) and _B. b. minima_ from Louisiana (Lowery, Occas. Papers Mus.
Zool., Louisiana St. Univ., 13:218, November 22, 1943) leaves the
identity of the specimens from eastern Texas in doubt. We have examined
the following specimens in the Biological Surveys Collection, U.S.
National Museum: No. 117372, from Joaquin; No. 136407, from 7 mi. NE
Sour Lake; and No. 136788, from 8 mi. NE Sour Lake. We judge these to
be the specimens referred to by Bailey (_loc. cit._). We find that they
are indistinguishable from specimens of _Blarina brevicauda minima_ and
they seem to differ from _B. b. plumbea_ in being chestnut rather than
plumbeous in color and in lacking the highly-arched posterior border of
the palate. They are easily distinguished from _B. b. carolinensis_ by
their chestnut, rather than slaty-black, color and small size. They are
distinguishable from _B. b. hulophaga_, to which they might conceivably
be referred on geographic grounds, by their color and small size. We
refer them to _Blarina brevicauda minima_ Lowery.
~Spilogale angustifrons angustifrons~ A. H. Howell
In his "Revision of the skunks of the genus Spilogale" (N. Amer. Fauna,
26, November 24, 1906) A. H. Howell identified certain specimens in the
United States National Museum as follows:
_Spilogale leucoparia_, [Male] sad. 55585 from Tulancingo, Hidalgo
(_op. cit._:21).
_Spilogale gracilis_, [Male] sad. 88154 from San Sebastian in
Jalisco, [Male] ad. 79017 from Lagos in Jalisco, [Male] ad. 47177
from Pátzcuaro in Michoacán (_op. cit._:23).
_Spilogale ambigua_, [Male] ad. 35667/20437 from Barranca Ibarra in
Jalisco, [Male] yg. 120101 from Ocotlán in Jalisco (_op. cit._:25).
Hall and Villa (Univ. Kansas Publ., Mus. Nat. Hist, 1:448, December
27, 1949) inferred that No. 47177 from Pátzcuaro was instead referable
to _Spilogale angustifrons angustifrons_. Our examination of No. 47177
and of each of the other specimens mentioned by catalogue number
immediately above leads us to conclude that they all are of one
species, and that, among named kinds of _Spilogale_, they should be
referred to the subspecies _Spilogale angustifrons angustifrons_
Howell.
