trochlea surface, instead of that of the inner side only as in the 

 antelope; and (3) the contour of the outer condyle of the proximal 

 trochlea which is broad and full, while the groove of the wide calcaneal 

 surface is medium and pronounced. 



CAPEOMERYX?, sp. 



Material. — A small astragalus, and a section of the distal end of an associated 

 metapodial, Univ. Calif. Coll. Vert. Pal. no. 23527a (figs. 1.5, 16), Univ. Calif, 

 loc. 3245. 



The astragalus (fig. 15) is considerably broken and worn. It is 

 distinctly smaller than any specimens of Capromeryx minor Taylor

from Raneho La Brea in the collections of the University of California. 

 It further differs in having a larger and deeper fossa, and in being 

 proportionately broader with the mid-dorsal groove of the proximal 

 trochlea surface more shallow. The specimens suggest the occurrence 

 of a small undescribed species of Capromeryx, even more diminutive 

 than the Rancho La Brea form, which represents one of the smallest 

 of Pleistocene ungulates. 



ANTILOCAPRA?, one or more species 



Material. — A basal portion of a horn core, no. 23453, and two sections of 

 smaller horn cores, no. 23420 (figs. 17, 180-186), all Univ. Calif. Coll. Vert. Pal., 

 general loc. Univ. Calif. 3247a. 



An astragalus, associated with a navicular-cuboid, a cuneiform, and pieces of 

 a caleaneum (figs. 13a-13c), nos. 24016, 23235, 23759, 23523, 23403, 24017, 2.3404, 

 Univ. Calif. Coll. Vert. Pal., Univ. Calif, loc. 3243. 



Discussion. — The specimens shown in figures 17 and 18 are of the 

 flat-horned antelopine type. They are believed to represent the basal
