both in the long diastema occurring between the first premolar and 

 the canine, and in the very small size of the canine teeth. No material 

 exists for comparison with the smaller mandibles described above under 

 P. edensis edensis, or Frocamelus, species A, to one of which species 

 the specimen may belong.

Material. — A long slender first phalanx and a referred metapodial trochlea, 

 nos. 23392 and 23391 (fig. 73, also pi. 48, figs. 8a, c); the proximal portion of 

 first phalanx, no. 23393 (pi. 48, fig. 8b) ; the proximal portions of several meta- 

 podials, no. 24032 (fig. 93c(), no. 23493; and seven astragli: no. 23383 (fig. 946), 

 no. 23382 (fig. 94a) with associated portion of tibia and tarsal joint; and nos. 

 22379, 23380, 709, 485, and 821. All specimens in Univ. Cal. Coll. Vert. Pal. All 

 from Univ. Calif. Eden localities. 



Discussion. — The long, slender phalanx (fig. 73) and other material 

 of this section suggests the presence of a large Procamelus-Wkc form 

 or forms. The scale drawings of various limb elements (figs. 71-73, 

 91-94, pi. 48) indicate the great size difference between the material 

 and that described above under Pliauchenia {fMegatylopus Matthew). 



The phalanx, no. 23391, is fully as long as those of the smaller 

 of the two foregoing Pliauchenia specimens, described under P. mer- 

 riami, but is noticeably lighter, the shaft being greatly constricted in 

 its middle region, wdiere it measures but 18 mm., instead of 27 mm. 

 as in species A. 



Another first phalanx, represented by the proximal portion, no. 

 23393 (pi. 48, fig. 8&) is somewhat smaller. It may represent the 

 opposite limb or a size variation of the first. 



A number of trochleas of equal size, nos. 23486 and 24032 (fig. 

 92fZ), and the proximal portion of metapodial no. 23493 (fig. 93a) 

 agree in general proportions with the foregoing phalanges and may 

 represent the same or similar species. 



The representation of more than a single species in the material 

 of this section is indicated in the variation in a fine series of camelid
