4. ARCTOCEPHALUS. 25 



broad (that is, four times as large) as the females. This may ex- 

 plain the difference in size of the skulls from the same localities. 



The fur changes its colour as the animal grows, the young being 

 generally black ; and the adult males and females also differ con- 

 siderably, in the colour of the fur. 



The skulls of the following species are not known : — 



4. Arctocephalus Forsteri. 



Grinders ^ . -|, conical. 



Arctocephalus Fosteri, Fischer ; Gray, Ann. Sj- Mag. Nat. Hist. 1868, 



i. p. 219. 

 Phoca ursina, J. R. Forster. 



Inhab. Cloudy Bay, New Zealand. 



This animal is only known from Dr. Forster 's description and 

 figure. 



Mr. Allen observes, "I can see no evidence of the New-Zea- 

 land Fur-Seal (of Forster) being specifically distinct from the Fur- 

 Seal of Australia, A. cinereus (auct.)." — Bull. Mus. Comjp. Zool. ii. 

 p. 15. 



At the same time Mr. Allen ventures to remark, " perhaps the A. 

 cinereus and the A. antarcticus are to be referred to*the A. falhlan- 

 dicus, in which case the habitat of this species is the southern seas 

 generally " (Bull. Comp. Zool. ii. p. 45) : but he does not seem to 

 have had specimens of any of the three species ; otherwise I do not 

 think he would have ventured upon the observation. 



Unfortunately, having no skull or other parts of the Lion Seal of 

 the Auckland Islands (the most southern of the New -Zealand group), 

 we are not able to determine whether it is the same species as 

 the Sea-lion of the southern end of the American continent (Otaria 

 jubata), or whether it is the Sea-lion of the southern end of the 

 African continent (Arctocejyhalus antarcticus), or the Sea-lion of the 

 Northern Australian Seas (Mojphoca lohata). 



5. Arctocephalus faMandicus. 

 Fur very soft, elastic ; hairs very short, exceedingly close, slender 

 at the base, thicker above, with close reddish under-fur nearly as 

 long as the hair ; the upper surface pale, nearly uniform grey, mi- 

 nutely punctulated with white ; hairs brown, upper half black, with 

 minute white tips. The nose, cheeks, temples, throat, chest, sides, 

 and underside of the body yellowish white.
