Mr. ALDERSON on a Whale of the Spermaceti Tribe. 255 
+ Circumference of the body at the spring of the tail 8 feet. 
The orifice of the spiracle, or breathing tube, was at the ex- 
tremity of the snout, and rather on the left side of the median line, 
somewhat of an f form, and 2 feet 4 inches in length, externally. 
There were two pectoral fins, in length 54 feet, in breadth 
2 feet 9 inches, at the broadest part, with ee furrows be- 
tween the phalanges. 
The glenoid cavity of the scapula, (the chord of the arc) 
measured 9 inches, and the articulating surface of the humerus 
measured 10 inches. 
Dorsal fin. This was only the rudiment of a fin; it was 
composed of the cutis and adipose cellular membrane, like the 
rest of the external covering of the body, and projected at its 
greatest height not more than a foot, commencing gradually, and 
terminating abruptly in a sort of Ne process posteriorly. 
Sex. Male. 
Tail, horizontal; the span from tip to tip measured 14 feet ; 
there were several transverse parallel bands distinctly seen upon 
it, where the epidermis was removed. 
The Eye was placed at nearly the greatest lateral projection, 
a little inferiorly ; the eye-lids were formed of a duplicature of the 
outer covering, about an inch in thickness; the upper lid pro- 
jected more than the under, somewhat like a flap, and the opening 
was about seven inches in length. 
There was no external ear, but simply a_ small circular 
opening about nine inches posteriorly to the posterior canthus of 
the eye, which just admitted the finger. 
ternal marks of this animal. “It is observed,” he says, “that this species has but one spout (fistula). This 
spout is not, as has been generally hitherto asserted, in the neck (cervix) of the fish, but in its front, and on 
the very edge of the head, bending obliquely on the left side, so that whenever he spouts it is always on that 
side only.” His description, however, of the “ peculiar bony triangular cavity, or trunk, which contains the 
spermaceti, and which is lodged near the brain, and occupies nearly the whole of the upper part of the head,” 
in no way agrees with my observations on the anima! cast on shore at Tunstall,
