Latreille {Fam. Reg. Anim.), in 1825, proposed to form the Seals 

 into an order. Amphibia, containing two families : — 1. Oynomor^ha, 

 for Phoea and Otaria ; 2. Brocha, for Trichechus. 



Wagler (JSTatiirl. Syst. AmpHbien), in 1830, places the Seals in the 

 order Ursi, and divides them into three genera : — 1. Phoeix (mona- 

 chus) ; 2. Bhinophoca (proboscidens) ; 3. Triehecvs (rosmarus). 



Professor Nilsson, in 1837, in a monograph of the species of Seals, 

 proposed to divide them into seven genera, distributed in two sec- 

 tions, thus : — 



Sect. I. — ^^1. StenorhyncJms (leptonyx) ; 2. Pelagius (monachus) ; 

 3. Phoca (vituUna). 



Sect. II. — 4. Halichoerus (grypus) ; 5. Trieheeus (rosmarus) ; 

 6. Cystophora (proboscidea and cristata) ; 7. Otaria (jubata and 

 ursina). See Vetensk. Akad. Handl. 1837, 235 ; Skand. Fauna, no. 20, 

 1840. This essay is translated into German by Dr. Peters in Wieg- 

 mann's Arch. vii. 301. 



In Loudon's ' Magazine of Natural History' for 1837 (i. 583) and 

 in the ' Zoology of the Erebus and Terror ' is proposed the arrange- 

 ment which is followed in this Catalogue. 



Mr. Turner, m 1848, proposed the following arrangement of the 

 family Phoeidce from the study of skulls : — 



I. Arctoeephalina : 1. Otaria; 2. Arctocephalus. II. Tricheeina: 

 3. Triohecus. III. PTiocina : 4. Morunga ; 5. Cystophora ; 6. HaU- 

 choerus; 7. Ommatophora ; 8. Lobodon; 9. Leptonyx; 10. Steno- 

 rhynchus ; 11. Phoca. — Proe. Zool, Soe. 1848, 88 ; Ann. ^ Mag. Nat.
