astragulus; a right calcaneum; two probably metatarsal sesamoids; 

 and first, second, and third, probably hinder phalanges. To these 

 remains, excepting the incisor, has been given the catalogue number 

 9193. This tooth and the bones are entirely too large to have be- 

 longed to any known species of Odocoileus and too small for any 

 known species of Cervus. The incisor (Cat. No. 9192) is consider- 

 ably larger than the corresponding one of the Virginia deer. It is 

 little worn. The crown is 8 mm. high and 7.5 mm. wide. The molar 

 is v>- orn down nearly to the base of the crown. The length is 20 mm. ; 

 the width 14.8 mm. There is a rather strong tubercle at the mouth 

 of the principal valley. The first molar of a wapiti at hand is 

 24 mm. long and 15 mm. thick ; in Odocoileus virginianus, 12.5 mm. 

 long, 9 mm. thick. The radius is represented by only a fragment, 

 50 mm. long; but the articular end is unfortunately a little injured. 

 The distal end of the ulna has been split off. The following meas- 

 urements of this part in the fossil in Odocoileus mrginianus and in 

 Cervus canadensis are presented : 



MEASUREMENTS OF THE DISTA.L END OF RADII IN MILLIMETERS. 



It will be observed that in size the distal end of the radius of 

 S. fugitiva is somewhat nearer the Virginia deer than to the wapiti. 

 The scaphoid bone is 26 mm. long and 32 mm. broad, these dimen- 

 sions in the Virginia deer being, respectively, 19 mm. and 26 mm. 

 The acetabulum of S. fugitiva has a length of 45 mm.; that of 

 O. virginianus 37 mm.; that of the wapiti 57 mm. The external 

 malleolar bone has a horizontal diameter of 26 mm. The calcaneum 

 has lost the epiphysis. The following measurements afford means 

 for comparisons : 



MEASUREMENTS OF CALCANEA IN MILLIMETERS. 



It will be seen that the bone in the fossil is a little longer than that 

 of the Virginia deer. It is possible that more is missing than the 

 epiphysis. The astragulus applies itself quite accurately to the cal- 

 caneum and may have belonged there originally. The width across 

 the surface for the tibia is 30 mm. The two sesamoids are those
