THE WHALEBOITE WHALES OF THE WESTERN NORTH ATLANTIC. 



The only real disci'epancy, it will be observed, is in the distance from the tip 

 of the snout to the posterior base of the pectoial fin. A glance at the figure will 

 show that the latter point is difficult to determine upon. 



In 1878 Sars published auothei' figure, based on a male having a length of 67 

 ft., Norwegian (= 69 ft., English) — {79, 3 and 4, pi. 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 : 



BALMSOPTEBA MUSCULUS (L.). NEWFOUNDLAND AND NOKWAT.

Tip of snout to eye 



" " " " blowhole (center) 



" " " posterior base of pectoral. 



" " " " " " dorsal.. 



Length of pectoral from posterior base.

Height of dorsal 



It will be seen that the ])rincipal differences between Sars's figure and the 

 Newfoundland s|)eciraens are in tlie moi'e forward position and greater height of the 

 dorsal fin and the greater bieadth 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 hannonious 

 with the average of the Newfoundland specimens.
