period and containing camel bones had been reworked during a later 

 Pleistocene time; for there is present the lower end of the fore-arm, 

 all the bones of the wrist (except the pisiform), and the upper end of 

 the cannon bone, evidently of one individual. 



The remains obtained from Professor Cannon are identified as fol- 

 lows: Equus, species indeterminable; Camelops huerf anensis ; Bison, 

 species indeterminable. 



Besides these there is present an astragalus of a prong-horn ante- 

 lope, but there is no certainty that it is not that of a comparatively 

 recent individual. 



EQUUS, species indeterminable. 



An indeterminable species of horse is represented by a right 

 third metacarpal (Cat. No. 8217), a left metatarsal (Cat. No. 8216), 

 and an anterior first phalanx. These have the appearance of having 

 lain in the same kind of deposit and may have belonged to the 

 same individual. The metacarpal has a total length of 244 mm. 

 and a side-to-side diameter of 37 mm. at the middle of the length. 

 The total length of the metatarsal is 268 mm. ; its side-to-side diameter 

 at the middle of the length, 37 mm. The length of the phalange is 

 78 mm. 



CAMELOPS HUERFANENSIS. 



Plate 116, figs. 1-7. 



What is believed to be Camelops huerfanensis is represented by a 

 number of fine teeth and by various bones. It is not known to what 

 extent the various bones and teeth were associated, but the teeth 

 were not probably found with the bones. Measurements are pre- 

 sented both of the teeth, and of some of the bones. Such measure- 

 ments may be of use in the identification of other remains. The 

 teeth are to be compared with those of the type of Camelops huer- 

 fanensis (Cragin). Those from Denver consist of a right fourth 

 premolar (pi. 116, fig. 1) ; a right first molar (pi. 116, figs. 2, 3) ; a right 

 second molar (pi. 116, figs. 4, 5) ; a right third molar (pi. 116, fig. 6) ; all 

 of the upper jaw. There is, besides, a lower left second molar which 

 appears not to have belonged to this individual, but to another of 

 about the same age. All of these teeth are those of animals mature, 

 but yet young. The hindermost molars are but little worn; and all 

 may be said to be in prime condition. In the table of measurements 

 here presented the height is given merely to indicate the stage of 

 wear. The specimen described by Cragin was a somewhat older 

 animal. In the columns showing the fore-and-aft lengths the first 

 number, where there are two, indicates the length at the summit; 

 the numbers in parentheses, the length taken near the base. The 

 first number varies with the amount of wear. The width is taken 

 near the base of the front lobe. The numbers in parentheses in the
