that the average length of the females is greater than that of the males. The 
measurements were made in a straight line from the tip of the snout to the notch 
between the tail-flukes. 
Mr. A. H. Cocks’ estimate of the average lengths of 94 Humpbacks, taken off 
the Northern Coasts of Norway and Russia in the years 1885 and 1886, is 351 feet 
in the case of the males, and 401 feet for the females.* From this it will be seen 
that the Southern members of the species are almost identical in size with their 
confreres in the Northern Hemisphere. 
Bopy Form. 
In general appearance, the New Zealand Humpback (Plates [. and II.) agreed 
exactly with the photographs and descriptions of Northern types.+ 
Proportional measurements, taken in the case of four adults and a large foetus, 
are shown in Table II.
