234 THE WHALEBONE WHALES OF THE WESTERN NORTH ATLANTIC. 
Humpback, but it is more likely that the figure is incorrect, as the nasals are made 
to end against the ¢nferior margins of the premaxille, which are inclined outward, 
so as to leave a much wider space between the superior margins. The distance be- 
tween the superior margins is about 7 %, which is a very close approximation to the 
breadth of the nasals in other specimens. The inclined position of the premaxillee 
in this figure causes the narial space to appear much shorter than in skulls I have 
examined. Another peculiarity of the figure is the very strong emargination of 
the orbital processes of the frontal anteriorly, and their emargination posteriorly 
also. This peculiarity may likewise be a characteristic of the Greenland Hump- 
back, but may, on the other hand, be merely an inaccuracy in the figure. In the 
absence of any other figure of the upper surface of the skull of a Greenland Hump- 
back it is difficult to decide the points at issue. 
VERTEBR2. 
The proportions of the vertebrx in the Tay River whale, and of some Amer- 
ican specimens, including the type of JZ. osphyia, are given in the following table:
