This was undoubtedly the commonest Cetacean in the Ross Sea. ‘‘ Killer” whales 
could be seen near the ship almost every day, so we did not attempt to keep a 
record of every occurrence. The above are only a few of the dates on which this 
whale was sighted. I have not much to add to the account of this whale given 
by*Wilson,* except that, on this expedition, we obtained evidence that the “ Killers” 
not only hunt along the edge of the fast ice in search of seals, but occasionally 
break up the ice with their backs, when it is not too thick, in order to dislodge 
seals which they see lying on the icefield.t 
“ Killers” were more common off the coast of the Antarctic lands than in the 
pack-ice, out at sea.

This whale was first seen by Wilson, when on the “ Discovery” Expedition. We 
saw a school of some twelve, or more, very clearly on February 9, 1911. They were 
about 30 feet in length, and the majority of them had long, pointed dorsal fins, as 
figured by Wilson.f{ In one case the concavity of the fin was pointing forwards. A few 
members of the school had shorter dorsal fins, exactly like those of Orcinus orca. 
The only points in which these whales appeared to differ from the ‘“ Killer” were 
in the uniform black colour of the back, and in the height of the dorsal fin. The 
variability in the size and shape of the dorsal fin in Orcinus orca is well known. 
On January 22, 1912, we saw a school of what were undoubtedly “ Killer” 
whales swimming near the edge of an ice-flow, on which some Adelie penguins were
