662 MR. J. W. CLARK ON EARED SEALS. [Dec. 7, 
the first half of their length, and to have a yellowish tip. The 
yellow extends further down the hair on the nape of the neck than 
elsewhere, giving a brindled appearance to that part. On the under 
surface of the body the hair is reddish brown. At the base of the 
hair is a dense growth of short delicate fur, of the same colour as 
the base of the hairs. 
Ina second specimen, rather older, which has been stuffed and 
set up in the British Museum, there are slight differences of colouring 
observable. The brindled appearance of the hair, caused by the 
hairs being tipped with white, extends all over the back and sides. 
The reddish brown extends over the underside of the body, and up 
the chest, where it gradually shades off into a pale chestnut. A 
space above and behind the mouth, and round the ear, is pale yellow. 
and there is a patch of dark grey beneath the eye. Ears light 
brown, black within. Fur on hands and feet dark brown, lighter 
near the body. The dark brown is shot with bright bay on the feet ; 
and there is a dash of the same, edged with yellow, behind the hands. 
Shorter whiskers black, hinder and longer ones white. 
The ‘“ manus’”’ (Plate LXX.) is of the form with which we are 
familiar in other Otaries; and the naked portion bears the same 
relation to that covered with hairs as in Otaria jubata (U1. c. pl. 67). 
The inner edge, however, is very different. There are only three 
rounded projections of cartilage, corresponding to digits I. If. IIL. ; 
and in the interspaces of digits I. and II., and II. and III., there is 
a second, less prominent projection. Beyond digit III. the limb is 
bounded only by a wavy edge. The movable portions of the digits 
and the intervening cartilages are much striated and folded. The 
palmar surface is puckered into large folds, which are crossed by 
smaller ones, so as to present a number of lozenge-shaped elevations, 
more or less regular. At the proximal end, these folds are minutely 
striated with sinuous cuticular elevations. 
There are indications of nails on the first four digits; on the 
last the nail is represented by a minute depression, hardly bigger 
than a pin’s point. 
The ‘‘ pes”? (Plate LX. XI.) has its upper surface covered with hair, 
which extends down the back of each digit quite to the nails, the 
intervening spaces and the terminal cartilages being quite bare. 
The “pollex”’ is closely united to the next digit by the intervening 
cartilage ; between the others the cartilage is very elastic, and 
admits of considerable movement. The under surface, like that of 
the hand, is broken into irregular folds, and is similarly striated at 
its proximal end. The three middle digits have nails 2 of an inch 
long. These are quite rudimentary on the first and fifth. The nails. 
fail to reach the free edge of the cartilage by about their own length. 
The distance between the end of the nails on the ‘‘ pes”’ and the 
free edge of the cartilages varies, no doubt, in each species. In O. 
ursina, to judge from Allen’s figure (Harvard Bulletin, ii. plate ii. 
figs. 11 & 12) the distance is 5 inches; in O. stelleri (ibid. plate i. 
figs. 6 & 7) it is barely | inch. In the “manus” of O. ursina only the 
first two digits are marked by projections in the cartilage ; and even
