ODOCOILEUS, species indeterminable. 



Plate 117, fig. 1. 



An indeterminable species of apparently this genus is represented 

 by one of the distal pulleylike articular ends of a cannon bone. The 

 diameter is 22 mm. One lateral face has been gnawed by rodents. 

 There is present also a first phalangeal bone which fits accurately 

 against the trochlea just mentioned (pi. 117, fig. 1). It has exactly 

 the length of a hinder first phalange of 0. virginianus, but it is con- 

 siderably slenderer. These bones have the catalogue number 10319. 

 The following are the comparative measurements :

SANGAMONA?, species indeterminable. 



A deer larger than any existing species of Odocoileus and smaller 

 than Cervus canadensis is indicated by a single bone, a left astragalus. 

 The hinder half of a left astragalus (Cat. No. 9193) found at Cave- 

 town, Maryland, and regarded as belonging to Sangamona fugitiva, 

 has the same width; but the groove for the lower end of the tibia is 

 deeper, and the inner ridge bounding this groove is thinner than in 

 the astragalus from Washington. The side- to-side thickness of the 

 bone taken at the middle of the length is close to 30 mm. The 

 astragalus of a specimen of Odocoileus virginianus is 43 mm. long on 

 the outer face, the width of the front end 29 mm. The length in the 

 fossil is 46 mm.; width in front 33 mm. Here again in 0. virginianus 

 and likewise in 0. hemionus, the inner ridge bounding the median 

 groove is thinner than in the fossil. For the present this bone is 

 referred to the genus Sangamona. This catalogue number is 10316. 



ALCES?, species indeterminable. 



In the collection there is an epiphysis from the lower end of a cannon 

 bone of a deer which had about the size of a moose. When com- 

 pared with a corresponding part of the moose some minute differ- 

 ences are noted. These probably indicate a distinct species, possibly 

 A. hrevitrabilis or A. semipalmatus , both of which were described by 

 Cope from parts of antlers found at Washtucna Lake, Oregon. Or 

 the bone may belong to Cervalces.
