NORTHERN ZOOLOGY. 
slightly dilated exteriorly at their bases, but can scarcely be termed tuberculated. In height, 
they equal the molar teeth. The inferior incisors are arranged in contact with each other in a 
convex line, and are very short. They have obtuse, slightly two-lobed crowns, which expand 
laterally beyond their roots. The upper canine teeth are conical, obscurely three-sided and 
sharp pointed. They stand twice as high as the molar teeth. The inferior canine teeth are 
of the same size with the superior ones, and have each a minute and rather obtuse lobe at 
the base on the inner side. The molar teeth have high, sharp, pyramidal points. 
The nostrils are two lines apart, turned a little outwards, and have a raised obtuse, naked 
margin. There is a depression between the nostrils superiorly, but no furrow on the 
margin of the lip, which is hoary within and without. The eyes are surrounded by fur, 
but situated clear of the ear and its tragus, The ears are shorter than the head, nearly 
circular, entirely covered with fur behind, except a small lobe, which projects anteriorly, 
and is overlapped by the tragus. On the inside there are some detached patches of hair. 
The margins are entire, and the folds around the auditory opening have a resemblance to 
those of the human ear. The ¢ragus is scalene-triangular, fixed by one of its angles, and 
is well characterised by Mr. Say as very obtuse at the tip, and arquated. It is thinly 
hairy exteriorly. The margin of the mouth and the chin are black and hairy; and the 
crown of the head and throat are yellowish-brown. The occiput, and the rest of the superior 
parts, are covered with a long and very fine fur, which is blackish-brown at the base, then 
shining yellowish-brown, followed by very dark umber-brown, and, lastly, tipped with white, 
producing a hoary and almost silvery colour on the back. The fur of the under parts is also 
hoary, but has less lustre. The interfemoral membrane is triangular, and at its apex there is a 
very slight smooth projection of the tail. It is hairy above ; its fur, towards the middle, being 
coloured like that of the back; but, near its margins, and particularly towards the apex, a 
reddish-brown tint prevails. The wing-membrane presents some small hairy patches above 
the elbow-joint, and at the roots of the metacarpal-bones. Underneath, it has a close coat of 
yellowish-brown fur on each side of the humerus; also a hairy patch beneath the brachial- 
bone, and others beneath the metacarpal-bones at their origin. The first finger has one 
joint; the second, three; and the others, two each. The thumb has one phalanx, which 
is much longer than its metacarpal-bone, and is armed with a short but strong, curved, black 
claw. The hind-feet are covered with hoary fur above, and have short, curved claws, which 
are excavated underneath.
