Diagnosis.
The weasels in this group are medium sized, and the tail
is medium length, about 1.5 times the length of a hind foot.
The length
of the body of the male (n = 14) is 162-213 mm
(M. 186), that of the female
(n = 9) 145-185 mm (M. 165).
The length of the tail is 28-66 mm (M. 40.5)
in the male and 20-42 mm (M. 33.6) in the female; the length of the hind
foot is 22-30 mm (M. 27.3) in the male and 19-25 mm in the female (M. 22.1).
The size of the skull is average for subspecies in the group.
The condylo-
1 basal length of the skull is 30.5-40.2 (M. 35.9) in the male (n = 13) and
