144 Eaton — Vertebrate Fossils from Ayusbamba, Peru. 



Lama sp. 



The fifth lumbar vertebra and portions of the right ilium 

 and ischium. The specimens compare closely with the corre- 

 sponding skeletal parts of a medium-sized animal of the recent 

 species, Lama huanachus. It is, of course, impossible to 

 assign the present specimens definitely to an} 7 one of the 

 several species of this genus that have been described from the 

 Pliocene and Pleistocene of Argentina and Brazil.

Odocoileus brachyceros. 



The material from Ayusbamba referable to this genus and 

 species includes a fifth cervical vertebra belonging to an 

 animal considerably smaller than a full-grown Virginia deer, 

 and also a number of fragments of antlers, picked up on the 

 surface of the lake-beds. Fortunately the basal portion of one 

 of the antlers has been preserved. ~No upright snag rises 

 from the base of the inner side of the beam, and the antlers 

 fork near the burr, the basal portion being extremely short. 

 These characters, together with the texture of the surface, 

 serve to identify the Ayusbamba specimens with Odocoileus
