The noses of the male and female differ in width as is 

 well seen in the collection of skulls in the Museum. 



McGill describes a skull, said to come from California, 

 in the " Proceedings of the Essex Institute " 1866, v. 13, 

 under the name of Macrorhinus angu.stirostris, which may 

 be from a female specimen.

 Suppl. Cat. Seals a)id Whales Brit. Mus. 6. 



Nose simple ; muffle rather large, callous above and 

 between the nostrils. Ears with a cylindrical external 

 conch. Arms and legs rather elongate. The fore and 

 hind feet fringed. Fore feet fin with a scolloped naked 

 membrane. Palms and soles bald, longitudinally grooved, 

 more or less triangular. Fingers gradually diminishing in 

 size from the inner side. Hind feet elongate, narrow, all 

 clawless. Toes nearly of equal length, the outer one on 

 each side being rather the strongest (see Cat. Seals and 

 Whales 44, f. 15). Three middle toes clawed. The fur is 

 generally provided with a more or less thick under fur. 

 Skull with a post-orbital process. An alisphenoid canal. 

 Mastoid process strong and salient, extending aloof from 

 the auditory bulla. Cutting teeth f , 4 middle upper bitid ; 

 Literal upper cutting teeth and canines conical ; grinders 

 ?- or f. The scapula is curved backwards to the upper 

 angle, but with its spine or crest near the posterior margin. 

 These animals are thus arranged — 



1. The palate produced behind the opening of the 

 inner nostrils just before the condyles. Upper giinders 

 6-6. Under fur sparse. Sea Lions. Otariina. 

 1. Otaria. 

 IL The palate shorter, with the o])ening of the inner 

 nostril some distance before the line of the condyles. 

 Sea Bears. 



i. Gypsophocina. The upper grinders 6-(), the fifth 

 and sixth quite behind the back edge of the front 

 of the zygomatic arch. 



2. Gypsophoca. 

 ii. Arctocephaliua. The upper grinders 6-6, the 



sixth behind the back edge of the front of tlie 

 zygomotic arch, the fifth is even with it, and is 

 sometimes rudimentary. 

 * Head elongate ; face produced in front. 



3. Phocarctos. 



** Head elongate ; face short, arched. 



4. Callorhinus. 

 *** Head broad. 



5. Arctocephalu.s. Crown of grinders broad, slightly 

 lobed. 



6. Euotaria. Crown of gi-inders compressed, lobed. 



7. Eumetopias. Fifth upper grinder soon deci- 

 duous. 



III. Zalophina. Upper grinders 5-5, the fifth in a line 

 with or before the back edge of the front of rlje 

 zygomatic arch. 



8. Zalophus. 9. Neophoca. 



These animals have been divided into many species, 

 founded on the accounts of travellers and defective figures. 

 In the " Catalogue of Seals and Whales " I have attempteil 

 to unravel these nominal species, but here I have onlv 

 referred to the species established upon the examination <if 

 specimens. 



Otaria, Gray. 

 Suppl. Cat. Seals and Whales B.M. 12. 



Sea Lions. 



Skull with the palate elongate, produced behind, the 

 opening of the nostrds just before aline drawn between the 

 condyles, tapper grinders 6-6. Under fur sparse. The 

 palate concave, becoming deeper and contracted behind 

 with age, nose and palate dilated in front in the males. 

 The flap of the toes very long. The ears small. 



Otaria jubata.

PL 17, fs. 1 and 2. The skull of a young specimen with- 

 out a lower jaw, received from Chiloe, in the BritisJi 

 ^luseum. Blainville described a skull in the Royal Col- 

 lege of Surgeons as Phoca Byronii, liut I cannot see any 

 difference between his skull and those in the Briti-^h 

 Museum. Dr. Peters, from a difference in the position of 

 the teeth in the figure, was inclined to consider it di.stinct, 

 but, on examination of the skull itself, he decided that the 

 figure was inaccurate in this respect.
