THE WHALEBONE WHALES OF THE WESTERN NORTH ATLANTIC. 165 
No. 3. Hemale. June 21, 1901. Total length, 73 ft. 10 in. Superior sur- 
face of the head to the eye, and as far back as the head of the humerus, uniform 
gray. The white spots of the belly are few and are confined to an area running 
obliquely from the base of the pectorals to the navel. Those of the two sides 
do not meet in the median line until nearly at the navel. From the navel to the 
clitoris the inferior median line is dark gray and without spots. On the sides of 
the body the light spots are exceedingly numerous and occupy a larger area than 
does the darker color. Their long axes have definite directions. They sweep 
around the base of the pectoral fin and are then directed obliquely downward and 
backward above the posterior ends of the abdominal ridges. They then point di- 
rectly backward, or those of the upper rows upward and backward toward the top 
of the caudal peduncle. The sides of the caudal peduncle have more of the light 
color than the dark, and the same is true on the shoulder. The pectoral fins are 
white externally for about 6 inches from the tip, but the light gray spots do not 
extend forward from the base as much as in No. 2. The base of the flukes under- 
neath is light gray anteriorly, with darkish fine lines running fore and aft, growing 
darker toward the posterior margin of the flukes, which is quite dark gray. (See 
‘pl. 18, fig. 2.) 
No. 4. Female. June 22, 1901. Total length, 73 ft. 6 in. The sides of the 
body have more light color than dark, except above the pectoral fins (when 
laid back). The light color extends forward to a line drawn between the eye and 
the inferior median line opposite the head of the humerus. ‘The inferior median 
line from the anus backward is plain gray. The spots of the two sides come to- 
gether in the median line between the navel and clitoris; behind the anus they 
extend downward but do not meet in the median line. White spots on the breast 
very few, not reaching the median line. White dashes about the sides of the anus 
and pudendum, From the dorsal to the flukes, the sides of the caudal peduncle 
are nearly all light colored up to within about a foot of the superior edge, where 
the color is nearly all dark. Base of flukes below finely lined with darkish gray 
streaks running fore and aft, but curving inward toward the median line. 
No. 5. Male. June 22, 1901. Total length, 68 ft. 3 in. A very light 
individual, light gray all over, the head alone being darker. The white blotches 
on the abdominal ridges are numerous and very white, and run off the posterior 
ends of the ridges along the flanks in the form of narrow elongated markings, quite 
unlike the elliptical gray blotches of some of the preceding specimens. Much white 
around the navel and some behind the anus. From a point about opposite the 
orifice of the penis, the white markings of the sides almost disappear, but they reap- 
pear in moderate abundance behind the line of the anus for a foot or two. This 
No. 5 has three large irregular white scars on the right side. The right pectoral 
has much of the posterior margin torn and irregular, and the tip broken. (See pl. 
18, fig. 1.) 
No.6. Male. June 24, 1901. Total length, 65 feet. The light blotches of 
the sides meet in the median line between the navel and orifice of the penis. They 
are especially numerous at the posterior end of the ridges and are whitest there.
