The upper surface of the skull is nearly flat ; itis much contracted 
between the orbits. The orbital processes of the frontals curve out- 
wards and backwards, and are truncated at their hinder extremity, 
which is free. From between these processes the face slopes slightly

downwards. The nasals are very long and narrow (fig. 8, p. 668). 
The preemaxilla, which projects forwards 15 inch beyond the nasals, 
is hollowed out at its sides, and terminates in a very marked knob, to 
which is attached the ligament which holds the cartilaginous snout 
in place. These last characters are well shown in Dr. Gray’s figure 
of his Euotaria cinerea (Hand-List of Seals, ete. plate xxvi.), based 
on one of the specimens sent by Dr. Hector from Milford Sound. 
Most of the teeth, however, have unfortunately been lost. There is 
a better figure of the same skull, with the teeth, in P. Z.S. 1872, 
p- 656, figs. 1, 2, where, as afterwards explained by Dr. Gray, it is 
wrongly marked Arctocephalus nigrescens; and I think that the 
appearance of a second subsidiary lobe on the posterior side of the 
molars is due to the artist having placed the skull in such a position 
that he saw the edge of the prominent internal cingulum.
