PEOCAMELUS FORMS WITH VERY SLENDER ELONGATED LIMBS 



Type. — An exceedingly long and slender metapodial, Univ. Calif. Coll. Vert. 

 Pal. no. 23422 (fig. 91), loc. 3269. 



Beferred material. — The distal portion of a small metapodial, no. 23498 

 (pi. 48, fig. 1); and a fragment of the distal end of a first phalanx, no. 23387 

 (pi. 48, figs. 2a, b). 



Description. — Specimen no. 23422 (fig. 91) suggests a tall, slender- 

 shanked, gazelle-like form, being of very small cross-section and yet 

 equalling in length that of large specimens of Procamelus robust us. 

 As viewed from the front this cannon bone is remarkably long and 

 slender; in lateral aspect the posterior outline is somewhat bowed

through thickening in the middle region ; posteriorly a deep groove 

 marks the junction of the two metapodials, which are firmly coossified 

 except at the distal separation. The distal ends are but little expanded 

 transversely ; they are more than proportionately developed laterally, 

 the trochleas having a strong backward inflection. The keels of the 

 plantar surface are very prominent.
