standing. The floe was between the ship and the whales. This enabled us to estimate 
the height ofthe highest dorsal fin in the school at about 5 feet. It was quite the 
highest fin which we saw on a “ Killer,” and it was about the same height as the 
fins in the school of “ High-finned” whales. We saw another school of “ Killers” with 
variable dorsal fins off Coulman Island, on February 11,1911. The “ High-finned ” 
whale seen on December 19, 1910, was among the floes of pack-ice, and Wilson 
estimated the dorsal fin as being about 4 feet high. My own opinion is that the 
“ High-finned” whale is probably only a variety of Oreinus orca, or possibly a new 
species of that genus.

On June 20, 1910, a school of about 100 individuals of this species approached the 
ship from the eastward and followed her all day. These dolphins agreed very well 
with the figures of D. delphis with the exception of having rather more white on their 
ventral surfaces, and their pectoral fins seemed to be entirely white.

On both the above dates a pair of these whales were seen playing under the bows 
of our ship. They seemed to roll over more than the other dolphins which we saw. On 
October 20 the 7. peronii came with a herd of “Dusky Dolphins,” but they kept 
separate. They were larger than Layenorhynchus obscurus. All the four specimens 
were exactly alike and agreed with Gray's figure,* except that the tail-flukes were quite 
white above and below. The demarcation between the black and white was very 
pronounced (text-fig. 14).
