side, which were on the lower part of the belly, about 1| inch or 

 2 inches asunder 1 . 



The lungs have three lobes on the right side, besides the middle one, 

 and only two lobes on the left side. The mediastinum is a broad thin 

 membrane. There is only one vena cava superior. The eyes are small, 

 and the inside is lined with an album pigmentum, like the Hon, &c. 



The Wolvereen \_Gulo luscus, Ursus luscus, Linn. 2 ]. 



The animal itself was black, with some white spots on the toes. Its 

 head is flat, very much like an otter's, and the whole animal lies squat 

 upon the ground : it has but small eyes, and a short tail. Its feet were 

 broader than usual in animals of this ske, and the toes were easily 

 spread out, and were a little webbed. It lived upon fish and flesh, and 

 would dive for fish : the colour, the shape, the way of life, made me 

 imagine that it was an otter peculiar to the place it came from, but it 

 was somewhat larger than ours. 



Upon dissection I compared it with the otter. The eyes were a good 

 deal the same ; the pigmentum album also, which did not come lower 

 than the optic nerve. 



The tongue I have saved for a preparation with the cartilages. The 

 os hyoides is attached to the head as in most animals ; the superior ring 

 of the trachea is broad and thin, passing up on the inside of the cricoid ; 

 but is not contiguous to the inside of the cricoid, excepting at the lower 

 edge of it ; for it flies inwards, and there is a circular space all round 

 the upper part of this cartilage, and inside of the cricoid. The rings of 

 the trachea meet at their ends in their most natural or easy position ; 

 but when they are opened they can fly asunder nearly half an inch, 

 and are connected by a thin membrane. The trachea is large. The 

 thyroid glands are very small : there is one on each side of the trachea 

 at the upper part, or rather opposite the larynx, and about an inch 

 from it ; the lower end is small ; they are of a yellow colour. 



There is a cavity between the head and atlas which makes the anterior 

 part of the capsule of that joint, as in the badger, &c. The contents of 

 the thorax are much as in the otter, or in other animals : however, the 

 ligament of the pericardium, lungs, &c. is not perforated as in some 

 animals. 



1 [It would seem from the name given to the beast, and the common use of the 

 masculine pronoun in its description by Hunter, that he had not known the sex 

 until after its death and dissection.]
