ForrusEs. 
Two foetuses only were obtained. One of these measured 134 feet in leneth and 
yas taken from a mother of about 44 feet in length, caught on July 24th, 1912. The 
measurements of this foetus have been given in Table II. on page 89. It had very 
nearly completed its uterine existence. The other embryo was taken from a mother of 
about 48 feet in length and some 60 tons in weight, which was killed off the Bay of 
Islands, New Zealand, on October 10th, 1912. This specimen (Plate IV., fig. 4) 
is 61 mm. in total length, and must be one of the smallest embryos known from any 
Whalebone whale. The general measurements are as follows : 
Total length to root of tail , : : 5 : : . 43 mm. 
Head-length . 5 : ° : : : ; ; . 25 mm. 
Taillength . : : : : : : ; . 18mm.

iene of longest digit . : : : 2) emm: 
nani of eye (between inner angles a ey eli) : : : . 1:5 mm. 
Hair-tubercles can be seen on the snout, arranged like those in the adult. There 
are four along the median line, between the nostrils and the tip of the snout; and a 
row of nine on each side of the beak, towards the outer edge. 
The manus has four digits. The third and fourth digits are much longer than the 
second and fifth. 
The tail-flukes are only just perceptible, when viewed from the dorsal or ventral 
aspect. It is hoped that a full account of this embryo will be published later. 
Foop. 
A careful examination of the stomach was made in many cases, but very few of 
the whales had any trace of food in their alimentary canals. This was not altogether 
a surprise, when one considered the relatively small amount of plankton obtained by 
the “Terra Nova” in her daily hauls off the north of New Zealand, during the months 
of July, August, and September, 1911. The only food organisms found in the stomachs 
were unidentifiable remains of Schizopoda. 
Hasits. 
The Southern Humpbacks, like those of the Northern Hemisphere, are somewhat 
slower in their movements than species of Balaenoptera. They seldom stay under 
water for more than seven minutes, between each two acts of respiration. They show 
a distinct partiality for coastal waters; and it was quite a common sight, on the 
coast of New Zealand, to see a school of three or more of these whales pass through 
the narrow channel between an isolated rock and the mainland (p. 94). This habit 
was formerly made use of, during the whaling season, by Mr. Cook of Whangamumu. 
He placed a wide-mesh net, made of wire rope, across the channel, some 50 yards 
broad, between a rock and the shore. A look-out was kept from the cliffs ; and when
