14 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 6l 



remains consist of a tooth, a part of a femur, parts of two tibia, two 

 astragali, three proximal, and two second phalanges. The tooth 

 presents all the characters of an upper left premolar of Equus 

 niobrarensis alaskcu. The grinding surface is 28 mm. long and 28 

 mm. wide. The protocone is unusually long, 16 mm. 



Mr. L. S. Quackenbush (op. cit., p. 91) states that he collected a 

 fragmentary pelvis of a horse on the tailings of a mine, at Fox Gulch, 

 not far from Dawson, Canada (fig. 1 (14)). The fossil bones occur 

 here in a muck, which overlies a bed of gravel. They are sometimes 

 found partly imbedded in the gravel. 



Lydekker (Cat. Foss. Mamm., Brit. Mus., pt. 3, pp. 78, 86, 87) 

 records the presence, in the British Museum of Natural History, of 

 part of the right ramus of the lower jaw of a young horse, a part of 

 a metatarsal, and a first phalange. These had been collected many 

 years ago by Rev. R. McDonald, on the Porcupine River, Canada. 

 The locality is not more exactly indicated ; but it was probably not 

 far from New Rampart House (fig. I (15)). 



On a map, which forms a part of his paper already referred to sev- 

 eral times, Mr. Quackenbush indicated (pi. 25) the localities in Alaska 

 and Yukon where up to that time horse remains had been discovered. 

 Four of these localities remain to be noted here. The first of these 

 (fig. 1 ( 16) ) is in the Seward Peninsula, on the Pilgrim River, south 

 of the Kuzitrin River. To Mr. Quackenbush there was presented, 

 by a civil engineer, Mr. A. Gibson, in whose statements he had full 

 confidence, a tooth of a horse, which had been found on the river 

 mentioned, and which is now in the American Museum of Natural 

 History. 



The three following localities were reported by the well-known 

 collector, Mr. Charles Sheldon, to Prof. Henry F. Osborn, and com- 

 municated by him to Mr. Quackenbush. At some point on the 

 Chandler River (fig. 1 (17)), at about latitude 67 ° north and about 

 longitude 149 west, Mr. Sheldon found a terminal phalanx of a 

 horse ; and this he presented to the American Museum of Natural 

 History. From some point along the Chena River (fig. I (18)), 

 east of Fairbanks, somewhat south of latitude 65 ° north and not far 

 from longitude 147 west, Mr. Sheldon reported the skull of a fossil 

 horse. Where this skull now is the present writer does not know. 

 Likewise, evidences of the existence of a fossil horse were found by 

 Mr. Sheldon somewhat north of Mount McKinley. This was ap- 

 parently not far north of latitude 63 ° north and somewhat west of 

 longitude 150 west (fig. 1 (19)).
