REPORT ON THE SEALS. 75 



On consideration of the whole question, therefore, I am not disposed to split up the 

 family Otariiclaj to the extent which has been done by Gray, Allen, and Burmeister, or 

 even by Peters in his earlier memoirs ; but to accept for the present at least the view 

 which Peters, unfortunately with too great brevity in the specification of the generic 

 characters, had adopted in his last monograph, 1 and to arrange the species under the 

 generic terms Otaria, Eumetopias, Arctocephalus. 



Otaria, Pdron. 



Otaria, Peron, Voy. aux terres austr., ii. p. 37, 1816. 



Professor Peters defines this genus as follows : — " Ears short (15-20 mm. long); hair 

 stiff and without under-fur. Bony palate elongated up to, or almost up to the hamular 

 pterygoids." In addition, I may state that the palate reaches almost as far back as 

 the transverse plane of the anterior borders of the glenoid fossae and is truncated ; 

 borders of palate are elevated so that its surface is concave ; in the male deeply so and 

 with the hamulars converging so as closely to approximate. Posterior nares contracted. 

 Vomer entirely concealed by palate, and not articulating with the floor of the nose 

 until it reaches the vomerine crest of the superior maxilla. Infraorbital foramen opens 

 in floor of orbit immediately above posterior border of maxillary root of zygoma. Pre- 

 maxilla articulates with outer border of nasal. 



Dentition — post-canines .

The skull has been described with so much detail in Part I., in the male, female, 

 and young, that it is unnecessary to repeat the characters here. Last upper molar 

 immediately behind posterior border of the zygomatic root of the maxilla. Mandible 

 with a very massive quadrequilateral subcondyloid process inflected strongly inwards ; 

 angle with tubercle distinct from subcondyloid process, lower border of body everted. 

 Muzzle broad in male. I may repeat that only one species has been referred in this 

 Report to the genus Otaria. 2

- It should be stated that Burmeister, so far back as 1868 [ZtiUchr. d. gcssamt. Naturwiis., Bd. xxxi. p. 294), 

 expressed the opinion that the Otaria godeffroyi of Peters is the same animal as the Otaria jubata of Forster, and that 

 the Otaria ullox of Tschudi and Peters is the female of Otaria jubata.
