TO Loomis — Camels of the Harrison Beds. 



species are described, of which S. MtcJicochi is commonest and 

 known by the most complete material, so may be used for a 

 standard for comparisons. 



Stenomyhis hitchcocki Loomis 

 This Journal, vol. xxix, 298-318, 1910. 



This species, known by several complete skeletons, has so far 

 been found only at one point, in a quarry near Agate, Neb., 

 in the Lower Harrison beds. It is characterized by the small 

 size, narrow molars, lower canine completely incisiform, lower 

 jaw deep, metacarpals separated the entire length. 



Stenomylw gracilis Peterson 

 Ann. Carnegie Museum, vol. iv, p. 41, 1906, and p. 286, 1906. 

 A larger species, rather rare, with narrow upper molars, 

 lower canine less incisiform, lower jaw slenderer, and meta- 

 carpals coossified a part of their length. Occurs in the Lower 

 Harrison beds. 



Stenomylus crassipes Loomis 

 This Journal, vol. xxix, p. 319, 1910. 



About the size of the preceding, but with lower canine com- 

 pletely incisiform, and the limbs much shorter and the skeleton 

 throughout much heavier. This form occurs in the uppermost 

 beds of the Lower Harrison. :
