168 THE WHALEBONE WHALES OF THE WESl'ERN NORTH ATLANTIC. 



as far forward as the middle of the right lower lip, and thei-e are a few white 

 dashes on the middle of the lip itself. Body veiy light around the head of the 

 humerus. Flanks nearly solid light gray from the line of the pudendum to the 

 flukes. Flukes very light nndei-neath, especially nearest the anterior margin. 

 Dorsal fin almost white except at the tip and about the posterior free mai'gin. Tip 

 of left pectoral white for about one foot or more externally, with lines and white 

 markings running proximally nearly to the middle of the length, and considerable 

 white along the posterior margin. No light blotches visible on the external face 

 of the left pectoral, but thei'e are some on the right pectoral. 



The right side in this whale appears to be lighter than the left. 



No. 15. Male. June 29, 1901. Total length, 63 ft. 6 in. A darkish indi- 

 vidual, with very little white on the I'idges, and there mostly close under the pec- 

 torals, especially at their base. The inferior median line broadly plain gray as far 

 back as the anus, though with occasional lighter blotches and marks. Dorsal fin 

 with only a few vertical curved light lines on the darker ground-color. (See pi. 

 20, fig. 4.) 



No. 17. Male. July 2, 1901. Total length, 65 ft. 8 in. A moderately light 

 individual. A cousidei'able number of white spots at the posterior end of the ab- 

 dominal ridges, but the clear white does not run on to the flanks. Posterior half 

 of the ridges much and finely speckled with dark-gray mai"ks on a lighter ground. 

 The belly and breast become darker anteriorly, and the navel region is, therefore, 

 the lightest part of the under surface of the body. Some white dashes about the 

 anus, but the median line posterior to the navel otherwise mostly dark and finely 

 mottled and lined. Back plain dark gray throughout. The lightest part of the 

 sides is midway between the line of the dorsal fin and the flukes. No white spots 

 anterior to the base of the pectoi-als. Dorsal fin with a 'white antero-basal area, 

 crossed by vertical curved gray lines. Flukes normal in coloi-, with fore-and-aft 

 light lines, or rather a whitish ground-color, with gray lines crossing it. 



No. 18. Male. Jvly 3, 1901. Total length, 72 ft. 2 in. Not a very light 

 individual. Flanks, from the line of the orifice of the penis backward, largely plain 

 dark gray. A moderate number of white spots on the abdominal i'idges posterior 

 to the pectorals, and these spots I'un off on to the flanks iuferiorly about as far as 

 the orifice of the penis. Scattered white mai'ks are found as far back as the anus. 

 Navel white. 



No. 19. Female. July 4, 1901. Total length, 74 ft. 6 in. Quite a light 

 individual, the sides being nearly all light gray from the line of the anus nearly to 

 the flukes. Shoulders the same. One or two light blotches on the right lip at 

 the anterior ends of the furrows. 



N). 20. Female. July 4, 1901. Total length, 70 ft. 3 in. The inferior half 

 of the sides of the body jiractically all light gray, thi'ongh the confluence of the 

 light blotches. The middle of the sides (longitudinally) posterior to the line of the 

 anus much blotched, and the blotches turn to streaks at the base of the flukes and 

 run into the lines of the underside of the flukes. Inferior median line posterior to 

 the navel blotched. A large amount of white on the abdominal ridges, especially
