OSTEOLOGY, a, b. Skull, male and female. Columbia River. 

 Presented by Hudson's Bay Company. 



This species does not, on the east side of the Rocky Moun- 

 tains, range further north than latitude 54, nor is it found in 

 trfat parallel to the eastward of the 1 05th degree of longitude. 

 Mr. Douglas states, " It is the most common Deer in the di- 

 strict adjoining the River Columbia, more especially on the 

 fertile prairies of the Cowalidske and Multnornah rivers, within 

 100 miles of the Pacific Ocean." 



In running the tail is erect, wagging from side to side. Its 

 gait is two ambling steps and a bound exceeding double the di- 

 stance of the steps. Richardson. 



Dr. Richardson described a female killed in February as fawn- 

 coloured, mixed with black ; tail fawn-coloured, white at the tip 

 and beneath. Mr. Douglas, however, described the upper part 

 of the animal as reddish brown in summer, and changing to light 

 grey in winter ; so his animal may be a different species. 



Skull elongate, narrow. Face rather produced, tapering, flat- 

 tened on the sides. Intermaxillars rather broad, not reaching to 

 the nasal bones, and fitting into a notch in the front upper edge of 

 the maxilla. Infraorbital pit moderate ; fissure very large, trian- 

 gular, open. Nasals, each notched in the middle of the fronts. 



Male : length entire 1 1 inches ; from front of orbit to nose 6 ; 

 width at lower edge of orbit 4f ; of nose just before first grinder 

 1; of skull 3. 



Female : length entire 9f inches; from front of orbit to nose 5|; 

 width at lower edge of orbit 3 T \; upper side of orbit 3^; of 

 nose just before first grinder 1 T 8 ; of skull 2 T \ ; suborbital pit 

 rather smaller than in the male. 



A male and female in winter dress, from Fort Colville on the 

 Columbia River, were sent by the Hudson's Bay Company to the 

 Museum May 26, 1843 : they arrived without hair or skin.
