4. Teeth: Two lower canines, one upper 

 canine, and one incisor fronn a 9-year-old (?) 

 male California sea lion. 



5. Fragments of one or nnore cetaceans, 

 possibly Dall porpoise. 



6. Miscellaneous bone fragments that could 

 not be specifically identified with material at 

 hand, 



7. Loose hairs found in the small intestine, 

 averaging about 15 nnm, in length and grayish 

 in color, were from a sea lion, probably 

 Zalophus . 



After examining the material, we concluded 



that the whale had recently consximed at least 



one California sea lion, one cetacean, and pos- 

 sibly as many as four elephant seals. For 

 identification the stonnach contents were com- 

 pared with material in the Bureau of Com- 

 mercial Fisheries Marine Mammal Biologica! 

 Laboratory collection.
