DECEMBER, 1903. MAMMALS ELLIOT. 241 



general color of upper parts being broccoli or hair brown instead of a 

 pale dingy brown ; the skull wider between orbits, and horns some- 

 what wider apart at tips. When a comparison of old ram skulls can 

 be made, other differences may be found. Mr. Heller's thirteen 

 examples were killed during the latter part of June and in July, and 

 it would be advantageous to have specimens taken at the same time of 

 year, as the color of the coat changes with the season somewhat, 

 although not to the same degree as is witnessed among the deer. All 

 of the thirteen specimens were females except one, a young male, no 

 old ram having been secured. The horns of the ewes are unusually 

 large for this sex, and have a wide spread at the tips. The figures 

 here given of the heads of the old ram and ewe (type specimen) show 

 very well the shape and type of the horns.
