104 DR. J. MURIE ON THE SEALS OF THE FALKLANDS. (Jan. 28, 
3. Another skin and skeleton (in better condition) of an adult 
and pregnant female, killed at the same time and place as the fore- 
going (No. 2). The foetus found in this specimen corresponded in 
size to the other. 
The colour of this skin corresponds in every particular with that 
described as No. 2, only it is not quite so dark. 
The maxillary and premaxillary bones of this skull are also partly 
broken by the fatal blow with the baton. The palate, however, a 
good character of the species, is entire. This demonstrates, as does 
the whole inferior region (compare figs. 1 and 2), ‘that the cranium 
of the female is much narrower and shallower than that of males of 
the same age and size. Especially is this the case in the maxillary 
region of the palate. The teeth altogether are much weaker and 
more sharply pointed than in the male. So marked is this that the 
skull of a female can at a glance, and by this character alone, be 
distinguished from that of a male. In some respects the female 
skull approaches that of Arctocephalus hookeri; but the posterior 
nares and great length of the palatines of both male and female 
Otaria jubata readily separate them. The greatest length of this 
cranium is 10°5 inches, the greatest breadth (at the zygoma) 6 inches. 
The crests of the roof are but feebly developed. 
4. Skin and skeleton (not perfectly complete) of a female Otaria, 
young but nearly adult. This was captured alive on the 4th June 
1868, at North-Point Island, situate at the south-east corner of the 
Falklands. 
In markings and colour this younger female is hardly to be dis- 
tinguished from the older pregnant animals. There is perhaps a 
more marbled aspect, produced by a greater and more irregular dis- 
tribution of the light upper hairs. 
5. Skin, disarticulated fragmentary skull, and leg-bones of another 
female, about the same age as No. 4. This specimen also was taken 
alive at North-Point Island, 4th June 1868. 
No difference in colour and hairy covering is appreciable between 
this and No. 4. 
6. Skin, leg-bones, and cranium, with imperfect dentition of a 
young but considerable-sized male Sea-lion. This animal was taken 
alive at Kelp Island on the 8th June 1868, and said to have been 
about eighteen months old at date of capture. 
The entire head, neck, and body of this skin is clothed with short, 
fine, smooth, closely set hairs of a nearly uniform chocolate tint. The 
nape of the neck and the belly are a trifle lighter than the other parts. 
7. Skin only of a very young male O¢aria, technically called a 
“pup.” Caught alive, 16th February 1868, on one of the islets 
near Kelp Island. This and the three succeeding specimens (Nos. 8, 
9, and 10) were seized at one raid. They shall be described and 
commented on together. 
8. Another skin, closely resembling the last. 
9. A skin, vertebral column, leg-bones, and feet of a similar very 
young but female Seal. 
10. Similar skin of another young female.
