160 THE WHALEBONE WHALES OF THE WESTERN NORTH ATLANTIC. 
The only real discrepancy, it will be observed, is in the distance from the tip 
of the snout to the posterior base of the pectoral fin. A glance at the figure will 
show that the latter point is difficult to determine upon. 
In 1878 Sars published another figure, based on a male having a length of 67 
ft., Norwegian (= 69 ft., English) — (79, 3 and 4, pl. 3). This is substantially the 
same as the figure of 1874, but differs a little in proportions. Compared with 
the ten Newfoundland males, which are of about the same size, the average per- 
centages are as follows:

It will be seen that the principal differences between Sars’s figure and the 
Newfoundland specimens are in the more forward position and greater height of the 
dorsal fin and the greater breadth of the pectoral. It is exactly in these particu- 
lars that the figure of 1878 differs from that published in 1874. On the other 
hand, in so far as these two figures agree with each other they are harmonious 
with the average of the Newfoundland specimens.
