 External Characters.^ — General color of adult light yellowish 

 brown, lighter on the head, darker and more reddish brown on the but- 

 tocks and limbs ; muzzle and naked membranes of the feet black. Young 

 dark chocolate brown, much darker than the adult, the coloration be- 

 coming gradually lighter with age. Females are said to be like the males 

 in coloration. 



Length of adult male from muzzle to end of tail about 6 to 7 feet, and 

 from the muzzle to the end of the hind flippers about 8 to 9 feet. Female 

 about one third less in linear measurements. 



The old males are described by the early voyagers as maned like a 

 lion, but this is in no strict sense true. The hair is longer on the neck 

 and shoulders than elsewhere, but the maned effect is due mainly to the 

 thick skin being thrown into heavy folds when the head is raised. 



Skull. — The skull of this species has been so often figured and is 



' The material collected by the Princeton Patagonian Expeditions relating to the Pinnipedia 

 not having been conveniently accessible during the preparation of this work I have drawn upon 

 previously published descriptions in dealing with their external and osteological characters. 

 Through the kindness of the authorities of the United States National Museum and the Cam- 

 bridge Museum of Comparative Zoology I have had opportunity to restudy a considerable series 

 of skulls of both the Southern Sea Lion and the Southern Sea Bears, and have utilized to some 

 extent material from my " Monograph of the North American Pinnipeds," published in 1880. I 

 am also indebted to the kindness of Prof W. B. Scott for Plate XXI, illustrating the skeleton of 

 Otaria bryonia, based on a mounted specimen from Patagonia, collected by the Princeton Pata- 

 gonian Expeditions.
