Santa Cruz Island, and also at Santa Catalina, where we called the same day. 

 There was evidence that all the animals had been killed for their oil. 



Bovid.e. Sheep, Bison, etc. 



We were informed by a resident that the mountain sheep is found among 

 the high, rugged hills on both sides of Concepcion Bay, but it is more 

 numerous on the ranges further inland. Only one was seen by our party. 



Our informant, Sr. Libera to Castro, from whom the horns were received, 

 said that we would find good sheep hunting on Tiburon Island, but no traces 

 of the species were found during our hunting there on April 12-13. The 

 name used at Concepcion Bay for the mountain sheep is " borrego cim- 

 maron." The species is found throughout the desert ranges of the eastern 

 side of the Peninsula, from west of the mouth of the Rio Colorado southward 

 to near La Paz.
