been submitted to us for examination, and the 

 nshes have been identified by Dr. Tarleton H. 

 Bean, Ichthyologist of the United States Fish 

 Commission. 



Of the 30 containing fishes, 15 contained red 

 rock fish or rock cod {Sebastichthys, 5 of which 

 were found in 1 stomach, making 19 in all), 2 

 contained salmon, 2 pollock (Pollachms cliaJco- 

 grammus), 2 ling, 1 stickleback {Gasterosteiis 

 catapliractus), and 9 small fishes too much digested 

 to admit of ready identification. Two contained 

 pebbles, and several intestinal worms. 



Although squids were found in only 18 of the 

 37 stomachs containing food, a large nrunber 

 were generally found in each stomach — as many 

 as 419 beaks in one instance, and 319 in another. 

 In all, 1,456 beaks, representing 728 squids, 

 were found in the 18 stomachs, an average of 

 40| to each seal. Owing to the small size of the 

 individual beaks, particularly those of the 

 younger squids, many were probably lost in 

 emptying and transferring the stomach contents, 

 so that the number here given is certainly below 

 the number originally contained.
