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

 plain the difference in size of the sktdls 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 th^ fur. 



The skulls of the following species are not known : — • 



4. Arctocephalus Forsteri. 



Grinders -J . -I, conical. 



Axctocephalus Fosteri, Mscher; Gray, Ann. ^ Mag. Nat. Hist. 1868, 



1. p. 219. 

 Phoca uisina, 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. cinerem (auct.)." — Bull. Mus. Oomp. Zool. ii. 

 p. 15. 



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

 cinereus and the A. antarctieus are to be referred to the A. falTclan- 

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

 generally " (BuU. 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-Hon of the southern end of the American continent (Otaria 

 juhata), or whether it is the Sea-Uon of the sou.thern end of the 

 African continent {ArctocepTialiis antarctieus), or the Sea-lion of the 

 Northern Australian Seas {Neophoca lohata). 



5. Arctocephalus falklandicus. 



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.
