SEA-LIONS, AND SEA-BEAHS. 33 



Grinders of upper jaw compressed, with an elongate triangular 

 central crown, with a collaret on the inner side, and a small lobe on 

 the back and often on the front of the collaret ; lower grinders broad, 

 with a small central longitudinal ridge divided into three small lobes, 

 the central one being the largest ; the fifth and sixth upper grinders 

 thickened, caUous, slightly divided into two roots. 



The difference in the shape of the lower grinders had escaped my 

 observation, for in the two adult skulls which we have in the British 

 Museum the crowns have been mostly broken off or chipped ; but on 

 very minute examination I find the crowns of two or three teeth in j 



one specimen perfect, and they present a decided difference in structure / 



from those of all the other Sea-bears. \

The Sea-bear of the Cape was first noticed by Forster, who called 

 it Phoca wsina ; then by Thunberg as Phoca antarctica ; then by 

 Cuvier as the Otaire du Cap (Oss. Foss. v. p. 220), who figured an 

 adult skull, t. xviii. fig. 5 ; and it was named Otaria Delalandn by 

 Frederic Cuvier, and the skull is figured by him in his memoir on 

 the skulls of Seals under the name of Arctocephale, considering the 

 species as Phoca ursina. A. Smith, in the ' South- African Quarterly 

 Journal,' described the Cape Seal as Otaria Peronii. In the T. Z. S.
