118 “TERRA NOVA” EXPEDITION. 
Land.* Liouville seems to have referred all the small Rorquals seen by him in the 
Antarctic to this species.f 
To sum up with regard to the Balaenopteridae of the Southern Hemisphere. 
It would appear that all the members of the family which are known in Northern 
latitudes occur all over the oceans of the Southern Hemisphere. Lalaenoptera musculus 
and B. acutorostrata penetrate in large numbers to the farthest shores of the ice-covered 
seas. B. borealis does not appear to be quite so common in the ice, while B. physalus 
and Megaptera nodosa do not seem to go further south than the outskirts of the pack. 
A new Rorqual has recently been described by Olsen} and called by him 
Balaenoptera brydei. Up to the present this whale has only been taken off the 
coast of South Africa. We of the ‘ Terra Nova” did not come across it at all.

Physeter catodon and P. macrocephalus, Linn. 
The only occasion on which we saw this whale was on March 31, 1912, when 
we were off the south of New Zealand in Lat. 44° 56’S., Long. 172° 53’ E. 
A school of twelve were seen very clearly. Towards the end of February, 1911, 
thirty-six bulls and one female were stranded on the beach at Perkins Island. 
Tasmania. The bulls appear to have been swimming after the cow, who took them 
into shallow water when the tide was receding, with disastrous results. A photograph 
of this stranded school was published in the Otago Witness for March 15, 1911, and 
is reproduced here. (PI. IV., fig. 1.)

We saw two specimens of this whale on March 10, 1911, swimming southward 
together. They were evidently old males, about 30 feet in length, and of a hght 
brown colour with white spots. Although we only saw this whale twice in the 
Antarctic, there seems to be no doubt that it occurs in these regions.¢ The whalers 
at the South Shetlands regard the ‘“ Bottlenose,” which they obtain in the far South, 
as identical with the species which they hunt off the coast of Norway.
