CAMELID? 



Material.— A scaphoid, Univ. Calif. Coll. Vert. Pal. no. 23397 (fig. 31), Univ. 

 Calif, loc. 3249, and the outer shell of a molar, Univ. Calif. Coll. Vert. Pal. no. 

 23762 (fig. 32), Univ. Calif, loc. 3262; and the distal portion of a phalanx. 



The small eamelid scaphoid (fig. 31) in the relative proportions of 

 the facets exhibits characters of Frocamelus rather than of Camelops, 

 interestingly resembling a lone scaphoid from the ]\Ierj'chippvis zone 

 of the Coalinga Miocene. The bone is considerably smaller than that 

 of the medium sized camel of Bautista. 



CERVID? 



Material— The distal half of an astragalus, Univ. Calif. Coll. Vert. Pal. 23763 

 (fig. 33), Univ. Calif, loc. 3262; and the distal portion of a phalanx (fig. 34), 

 Univ. Calif. Coll. Vert. Pal. 23761, Univ. Calif, loc. 32.51. 



The specimens suggest the presence of a cervid of medium size. 

 The outer condyle of the inferior trochlea of the astragalus is broad,

the adjacent groove is sharply defined, and the two condyles of the 

 trochlea, as seen mid-dorsally, terminate at either end of the connect- 

 ing ridge in knobs, as in the deer. The seeming non-deer-like shallow- 

 ness of the groove of the distal end may be attributed to abrasion 

 rather than to antelope affinities. The portion of a first phalanx 

 (fig. 34) is also tentatively referred to the deer; its characters are 

 broad, cervid-like, and not narrowed and elongated as in the antelope. 



PLIOHIPPUS FEANCESCANA, n. sp. 



Type. — A complete upper series of worn cheek teeth from right side of the 

 jaw, series no. 23277 (folder 3, figs. la-\b), found associated with the three 

 molars of the left side, nos. 23261, 23261a, 23262 (figs. 35a-35&), Univ. Calif, loc. 

 3253. To the type are referred three unworn upper teeth, nos. 23270, 23278,
