is grayer on
most, or all, parts of the pelage, has less ochraceous on the sides, and
the dark stripes on the sides of the head are narrower and less reddish
(more grayish). The skull of _caurinus_ is larger in certain
measurements, as shown below:

Howell (_op. cit._:75) referred three specimens from Glacier Basin, on
the northeastern part of Mount Rainier, to _T. a. ludibundus_ as he did
also one specimen (_loc. cit._) from Reflection Lakes, on the southern
flank of the mountain. Our comparisons indicate the correctness of
Howell's identification of the specimens from Glacier Basin; they more
closely resemble _ludibundus_ than _caurinus_. The specimen from
Reflection Lakes, however, is only one of five or six from the same
place; the others were lumped by him among the 49 that he recorded from
Mount Rainier under the name _caurinus_. The series from Reflection
Lakes, so far as we can detect, is not unusually variable and the
differences that are apparent are within the normal range of variation
ascribable to season, age, and individualism. Also, the series from
Reflection Lakes, to us, is not appreciably different from the other
series, representing the following places on Mount Rainier: Indian
Henrys, 5300 ft.; W slope Mt. Rainier, 6600 ft.; St. Andrews Park, 5500
ft.; Spray Park, 5500 ft.; Pa
