As reoards enemies, I judge that this species is little troubled b\’ the 
skua (Caf/mracfa) , the scourge of the P][^osa’/is rookeries. Its eiieuR^ iu 
the ocean is the sea leopard {Hvdrurga leptonyx^. From the stomach of 
one of the.se .seals killed at the Bay of Isles, early iu the moruiug of 
January 14, 1913, I took the remains of four king penguins, besides fish 
and other material. The magnitude of this breakfa.st may be more fully 
ajipreciated if I record that the weight of mature king ])enguins from the 
Lucas Glacier colony averaged 20 kilograms. 
Measurements in millimeters of 20 king penguins collected at South 
Georgia, are as follows :
