608 PROCEEDINGS OF THE NATIONAL MUSEUM. vol. 5». 



In the United States National Museum there is a first phalange of 

 a camel which was found in 1912 by Copley Amory, close to the 

 Alaska- Yukon boundary, at a distance of 50 miles above the mouth 

 of Old Crow River. This locality is 100 miles north of the Arctic 

 Circle and about 175 miles south of the Arctic Ocean. The bone, is 

 complete, except that a chip from the lower side of the anterior artic- 

 ular surface is broken off. The bone probably belongs to a fore 

 limb. It is here compared with a first phalanx of Procamelus major 

 from Florida, and with the anterior first phalanx of Camelus drome- 

 darius (p. 607), and with the first phalange of Camelus maximus. 



Measurements of first phalangeal bone of camels. 



Length of bone in median plane 



Fore-and-aft diameter of proximal articular surface. 

 Side-to-side diameter of proximal articular surface. . 



Fore-and-aft diameter at middle of length 



Side-to-side diameter at middle of length 



Width of articular surface at distal end 



The measurements show that the phalanx of the arctic camel is 

 larger in every way than that of the dromedary. It is more flat- 

 tened, especially in the shaft, than either the dromedary or Pro- 

 camelus major. The distal articulation is carried back on the hinder 

 surface as it is in the dromedary. The hinder face of the shaft is 

 fiat and even somewhat excavated. It is a slenderer bone than that 

 of C. maximus. 



The relationships of this camel seem to be with Camelus rather than 

 with Camelops and Procamelus; and to Camelus it is referred. 



A notice of this discovery was published by Mr. J. W. Gidley in 

 1 9 1 3 B but no systematic name has hitherto been applied to it. 



With the camel bones above described from Christmas Lake were 

 collected three astragali of horses, one of which is small, one of medium 

 size, and one large; also a first, a second, and a third phalange of 

 perhaps three horses; also a symphysis of the lower jaw of a small 

 horse; also a first and a second phalange of a large deer, possibly a 

 species of Sangamona; lastly, some fragments of a tusk of a pro- 

 boscidean. 



3. ON A SMALL COLLECTION OF FOSSIL MAMMALS MADE IN CHELAN 

 COUNTY, STATE OF WASHINGTON. 



In the United States National Museum there is a small collection 

 of bones and teeth which were collected probably in 1897, by a settler 

 named Parrish, on his place in the southwest quarter of section 23,
