THE WHALEBONE WHALES OF THE WESTERN NORTH ATLANTIC. 217 



(1) Specimen about 40ft. long. Throat, with its furrows, and nearly all of its 

 under side, white ; part of under side of flukes white ; pectorals black above, white 

 below, the black extending around the edge to the inner side, with an occasional 

 blotch of black, and 2 or 3 black rings. 



(2) Specimen about 44ft. long. Under side entirely black, except two white 

 or marbled patches on the chest, just behind the flippers, and one or two very 

 small white spots on belly; navel partly white; pectorals entirely white below, 

 above with proximal quarter black, but black stopping short of anterior margin. 



(3) Specimen about 30 ft. long. Almost entirely black on the under side of 

 body; pectorals white below, and only black above a little distance from proximal end. 



Cocks gives additional notes on specimens captured in 1885, as follows (J7, 

 4 sep.) : 



(1) Male, about 35 ft. long. Entirely black on under side of the body except 

 a not clearly-defined patch of white near each point of the under side of the flukes ; 

 some very small spots of white on chin and belly (due to barnacles). Pectorals all 

 white below ; above, black for a very short distance at the proximal end. 



(2) Specimen 44ft. long. Pectorals above with the proximal quarter black, 

 the black extending down the anterior edge, with a few small irregular black 

 marks lower down. 



(3) Male, 42 ft. long. Entirely black on the belly, but nearly the whole 

 chest and throat white; chin black, with a few small white flecks. Furrows on 

 the belly light purplish flesh-color. A small white streak on the upper lip. Very 

 little black on the outside of the pectorals, including a narrow rim along the 

 hinder margin. 



(4) Small male. Chin black ; some white on lower jaw ; throat and chest 

 white as far as posterior end of furrows; remainder of under side black. 



Struthers's notes on the color of the Humpback obtained in the Tay River, 

 Scotland, in 1883, give the following points (87) : All black, except the snow- 

 white under surface of the flukes and pectorals, and certain spots and streaks of 

 white about the navel and genital orifice. (Color of the upper surface of the 

 pectoral uncertain.) 



Sars, describing the Finmark Humpback (80, 14), states that the color on the 

 head and lower jaw is black, in the middle of the throat and breast, white, and 

 elsewhere on the parts variegated white and black, with rings and spots. The 

 back, sides, and the whole of the body behind the middle, black. Pectorals white 

 on both sides throughout, sharply defined from the black color of the body, but 

 with an ill-defined dark shading on the upper surface at the base. Flukes black 

 above and below, with white rings along the posterior border, on both surfaces, but 

 more numerous below. 



Rawitz furnishes the following data relative to the color of the four Hump- 

 backs examined by him at Bear Id. in 1899 (74, 74) : 



Male; length, 12.7 m. Back and sides black. Tip of mandible black, with 

 lighter places only here and there about its base. The knot-like projection on the 

 throat also black, but with linear transverse white flecks anteriorly. From the 

 projection to the line of the corner of the mouth the color is almost entirely white, 

 stretching only half as far back on the left side as on the right. Middle of throat
