THE FINWHALE FISHERY OF 1885. 125 
think, without exception, scars where Diadema coronula had 
been. There was a large cluster of small examples of this 
cirriped on the chin, another on each side on the fold of skin 
covering the penis, a small cluster on the back a few feet from 
the head, and some on the flippers. The examples were all 
small, none being of larger diameter than a florin, and there 
were no examples of Conchoderma auritum, unless there were any 
on the extreme point of the chin (at the symphysis of the lower 
jaw, which was still under water when I left, when it was getting 
dark. I noticed that Diadema coronula can see on land, at a 
distance of about one inch, the ‘‘cirri”’ of live examples being 
retracted when my finger approached within about that distance 
of them. The flippers of Humpbacks are invariably (with the 
infrequent exception of a few very small marks) all white on the 
inner side, but the coloration on the outer side varies considerably. 
In this individual they were black for only-a very short distance 
at the proximal end. The lower jaw measured 12 ft. 10 in. 
in a straight line. The fin of the Humpback rises very 
gradually from fore to aft; a better way of describing it, perhaps, 
is to say that the line of the back rises gradually for a length of 
about 4 ft., of which the after 1 ft. 4in. (as in this example) 
comprises the actual fin, the posterior free edge being deeply 
indented, almost a semicircle, and measuring (in this example) 
83 in. from the upper point to the line of the back. The back 
behind the fin continues level with, or slightly lower than, the 
line of the back anterior to the base of the fin. The next 
morning I found that three Humpbacks had been brought in 
during the night to one of the factories, and two of them were 
already flensed. One of these measured 44 ft. following the 
curves; the other was two or three feet shorter. The flipper of 
the larger of these two measured 14 ft. 4 in. in length, and that 
of the smaller 13 ft. 10 in. in length, and 8 ft. 44 in. across at 
the uppermost projection. About the proximal quarter of the 
outer side of the flipper of the latter was black, the black 
extending down the anterior edge, with a few small irregular 
black marks lower down. The third specimen, a male, 
measured 42ft. along the curves, and was entirely black on 
the belly, but nearly the whole of the thorax (i.¢., chest 
and throat) was white, the chin being black, with a few small 
white flecks. The concavities of the plaits or ribbings were of a
