REPORT ON THE SEALS. J7 



Skeleton. — Neither of tbe two skeletons from Fullers Harbour had reached adult life, 

 as the epiphyses of the long bones and the plates of the vertebral bodies were not 

 ankylosed to their respective bones. 



Skull. — In each of the larger crania the occipito-sphenoid synchondrosis was 

 ankylosed, but the joint between the two divisions of the sphenoid was yet open. 



The principal dimensions of the crania are given in Table V. : — 



Table V. — Crania of Kerguelen Island Fur-Seal. 



Although the ossification of these two crania was so far advanced, yet they possessed 

 no sagittal or interfrontal crest, and there was only the faintest indication of a crest in 

 the occipital region. On the supposition that these crania were males, as was surmised 

 by Professor Peters from an examination of the smaller of the two specimens, it would 

 appear that in this species of Arctocephalus the development of cranial crests scarcely if 

 at all occurs. 



The dentition was the same in both skulls, and the formula was as follows : — incisors 



36. The first and second upper incisors possessed 



canines 



-, post-canines 



2-2' 1-1"" 5-D 



the customary anterior and posterior cusps. Both the upper and lower canines had only 

 a single large cusp. The greatest interval between the post-canines was between the 4th 

 and 5th and the 5th and 6th, the interval between the last named being the widest. 

 The 6th post-canine was the smallest, and both it and the 5th in the upper jaw had 

 two diverging fangs ; the remaining upper post-canines had only a single fang. The 5th 

 lower post-canine was two-fanged ; the remainder one-fanged.
