4 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. I3I 



of Diplobimops and the others are of Protoreodon, Malaquiferiis, and 

 Eomoropiis. It is particularly noteworthy that although often much 

 fractured, the remains show almost no distortion, a condition unusual 

 in collections of Eocene age, particularly those from the Uinta basin. 

 The bone for the most part is a light buff color and the teeth amber to 

 dark brown. The beds themselves do not resemble exposures of the 

 Uinta formation in Utah but much more closely resemble the light 

 gray-green middle Eocene reworked volcanic ash of the Bridger for- 

 mation in southwest Wyoming. The upper Eocene fossil-bearing beds 

 in the Badwater area have been named the Hendry Ranch member 

 by Mr. Tourtelot and regarded as a part of the Tepee Trail forma- 

 tion. Definition and description of these beds are included in part i 

 of this paper.
