ens from northern
Sinaloa, two (85379-80) from 3 mi. N, 1 mi. E San Miguel, 350 ft., and
two (75386-87) from 2-1/2 mi. N El Fuerte, provide the first records of
the species from the state. _N. a. melanura_ has been known previously
from adjacent parts of Sonora and Chihuahua (see Hall and Kelson,
1959:687-688). The specimens from northeast of San Miguel were trapped
in runways under cholla cactus, in which nests also were found, on a
slope above a rocky arroyo.

_=Spilogale pygmaea=_ Thomas.--Two pygmy spotted skunks from 5 mi. NW
Mazatl['a]n (85898-99) are the fifth and sixth of the species to be
reported (see Van Gelder, 1959:381) and the second and third taken in
Sinaloa (the holotype of _pygmaea_ was obtained at Rosario). One of our
specimens, an adult male, was shot on the night of January 10, 1961, as
it foraged near an old hollow tree in weedy-thorn bush habitat adjacent
to the Pacific Ocean. The hollow tree contained the nest of a woodrat.
The second, an adult female, was trapped nearby in a commercial rat trap
baited with peanut butter and set near a burrow in a forested area
having little undergrowth.

The two individuals here reported fit fairly well the description
of color pattern given for the species by Van Gelder (_op. cit._:
379), but are larger (considering sex), externally and cranially,
than any of the four specimens reported previously. Measurements of
the male and female are, respectively: total length, 291, 270;
length of tail, 65, 58; length of hind foot, 38, 35; length of ear
from notch, 25, 23; weight in grams, 247.0, 190.5; condylobasal
length, 46.0, 42.9; occipitonasal length, 45.0, 41.4; zygomatic
breadth, 29.0, 27.3; mastoid breadth, 23.9, 22.5; interorbital
constriction, 14.3, 13.6; postorbital constriction, 14.8, 14.1;
palatilar length, 15.6, 14.6; postpalatal length, 23.2, 22.4;
cranial depth, 16.6, 15.2; length of maxillary tooth-row, 14.2,
13.4. Cranial measurements were taken in the manner described by
Van Gelder (_op. cit._: 236-237).
