bryde's whale. 1081 



The distance between these rows in adult specimens was about 

 18 mm., or a little more than between the successive hairs 

 in each row. Outside the upper end of these rows were two 

 other hairs on each side, placed at the same distance from the 

 long rows as between the rows themselves. I noticed no haii's on 

 the upper jaw. 



The number of hairs is thus 28 in all. On two foetuses, with 

 a length of 3'78 and 0'93.5 metres, the hairy covering was as well 

 developed as in adult specimens. The length of the hairs was 

 from 5-10 mm. 



Colour. 



The upper side of the body — -above the flippers — is bluish black, 

 and in colour much resembles the fin-whale. After death the 

 colour on this part becomes almost entirel}' black. On the sides 

 of the body the colour becomes gradually lighter, and there is no 

 sharply defined border between the dark colour of the upper 

 side and the white belly. The flippers are of the same colour as 

 the back above, or sometimes darker ; below they are grey, 

 occasionally whitish grey. The under side of the head, and a 

 band extending to about 0"70 meti-e below the flippers and 

 backwards to their tip are bluish grey. The centre of the belly 

 is a more or less yellowish white. In the dark area below the 

 flippers some isolated white spots may sometimes be seen ; similar 

 white patches are occasionally distributed along the centre of the 

 under side of the lower jaw, and more rarely a small white line 

 runs out from the white area on the belly to within one metre or 

 less behind the tip of the lower jaw. On the border between the 

 dark colour of the throat and the white belly there are often a 

 number of bluish grej^ patches or sti^ipes, and these are more 

 thickly sprinkled towards the front, and then gradually form a 

 more uniform dark colour in front of the angle of the mouth. 

 Between the tip of the flippers and the umbilicus — at the posterior 

 end of the long furrows — the white colour of the under side is 

 generally interrupted by a bluish grey belt running across the 

 stomach. This belt, which has a breadth varying between 0'70 

 and 1'5 metres, is often formed by a large number of smaller 

 and larger patches or stripes, not of uniform colour ; in other 

 cases it is verj^ little developed. 



Considerable variations occur in the breadth, size, and shape of 

 the white area on the belly. 



From the genital opening to the tip of the tail-flukes the 

 whole under side is dirty white, sometimes yellowish or whitish 

 grey. This white area begins above the genital opening at the 

 middle line of the sides of the body, and in some specimens is 

 further back and becomes gradually narrower. 



From the tip of the upper jaw, near the roots of the baleen, 

 sometimes a white stripe runs backwards, and the length of 

 this is about 0*5 metre and the breadth 5-7 cms.
