from Meadow Valley Region, S. Nevada. 269 



Pliauchenia% sp. 



A nearly complete fore-foot, No. 23916, fig. 8, collected 

 at locality 3546, belongs to a rather large species of 

 camel presumably of the Pliauchenia type. A single 

 astragalus, -Q-g. 9, from locality 3547, is perhaps also 

 referable to this genus. 



The individual represented by the fore-foot, No. 23916, 

 approaches in size certain of the camel types known from 

 the Eicardo Lower Pliocene of the Mohave Desert, 

 California. The Meadow Valley species resembles in 

 size the Camelops-like"^ form from the Upper Etchegoin 

 Pliocene of California, but it does not approach in this 

 character the genus Camelops from the Pleistocene of 

 Eancho La Brea. 



The camel from Meadow Valley differs from Pro- 

 camelus^ from the Barstow Miocene of the Mohave Desert 

 in possessing a shorter and more robust cannon bone, 

 larger and heavier phalanges. No. 23916 is decidedly 

 larger and heavier than limb elements of Procamelus 

 known from the Upper Miocene Cedar Mountain beds of 

 Nevada. 



The anterior caimon bone is badly crushed, particularly 

 the posterior side. At the distal end the articulating 

 surface for the inner digit is noticeably larger than that 

 for digit 4.
