THE WHALEBONE WHALES OF THE WESTERN NORTH ATLANTIC. 



specimeus seem to Lave been rather unusually white. More evidence is required 

 before Rawitz's tentative hypothesis can be accejited. 



In the majoi'ity of the descriptions of European Humpbacks the color of the 

 dorsal iin is not specified. Van Benedeu states that the posterior part is white 

 (7, 113). Sars represents it as dark like the back. In Newfoundland specimen 

 No. 5, the dorsal was black with small irregular white marks ; in No. 6, the dorsal 

 was blotched and spotted with white on the anterior niai'gin ; in No. 21 also there 

 was some white on the anterior margin. 



PROPORTIONS. 



While at the Snook's Arm whaling station, Newfoundland, in 1899, I made 

 measurements, as already stated, of three Hum[)ljacks, one male and two females. 

 These measurements are given in the following table :
