« Average number of embryos of 41 females; average measurements and weight of 32 females; the largest 
three and smallest six being excluded. 
CONCLUSIONS 
The pelage of males is comparatively uniform, except that the older ones are 
rather ragged, chiefly due to fighting. The series of females is much more 
variable and may be divided into (1) a grayish group which, on the whole, con¬ 
tains a majority of the oldest individuals, many of which are grayer than any 
male; and (2) a brownish group composed chiefly of smaller subadults, but among 
which are a number of older individuals. The second group averages somewhat 
more brownish than the brightest males. Other things being equal, the larger 
and*older the animal the longer the pelage. The feet of adults average paler 
than those of subadults. Juveniles are characterized externally by a slightly 
darker appearance and shorter, more compact pelage, although some of this 
indication of immaturity persists in sexually mature individuals. 
A grouping of the whole series with reference either to weight in the flesh or 
condylo-basilar length of the skull gives results eminently more satisfactory and 
natural than when they are grouped according to the head-and-body measure¬ 
ment.
