and other South-Sea navigators. According to Dr. Hooker, the Fnr 

 Seals of the Falklands rarely exceed 3| or 4 feet in length. 



Seamen have long divided the Seals, on account of the great dif- 

 ference in their form, into the Earless and Eared Seals. Buffon 

 adopted the division ; and Peron, in his account of Baudin's Voyage 

 (ii. 37), gave the name of Ofaria to the Eared Seals. Cuvier and 

 most naturalists have adopted this name. 



In the 'Medical Repository' for 1821, p. 302, I considered the 

 Seals as forming an order, named Awj^hih la , containing two families : 

 Phocadte for Plioea and Otaria, and Trichecidce for Trichecus. 



Dr. Fleming, in 1822, placed the Otters (Lutra), Sea Otters (En- 

 hydra), Seals (Phoca), Ursine Seals {Otaria), and Walrus {Trichecus) 

 in a single group, which he called Pulmata. — Phil. ZooJ. ii. 187. 



Dr. W. Vrolik, in 1822, in his ' Thesis de Phocis,' divides the Seals 

 into five tribes: — I. Phocce sine aurindis: Trihus prima, P. ^^tu- 

 lina ; Trihus secunda, P. monachus ; Trihus fertia, P. mitrata ; Trihvs 

 qm(rta, P. proboscidea. II. Otarice {Phocce aiiiiculata') : Trihus 

 quinta, P. leonina, &c. 



In the ' Annals of Philosophy ' for 1 825, I considered the genera 

 Phoca and Trichecus as each forming a familj', and proposed to 

 divide the Seals thus : — I. Grinders manj'-rooted ; ears none ; nose 

 simple. \. Stenorhiinchina,YQ\-d^msi and Stenorhynchus. 2. Phocina, 

 Phoca. — II. Grinders with simple roots, or with divided roots, and 

 Avith distinct ears. 3. Euhydrina, Enhj'dra. 4. Otariina, Otaria 

 and Platyrhynchus. 5. Steiumatopina, Stemmatopus and Macro- 

 rhinus. 



M. F. Cuvier, in 1825, in the * Dents des Mammiferes,' 118, divides 

 the Seals into those which have many roots to the grinders, including 

 P. vitidina, P. Leptonyx, and P. mitrata, and those witli simple- 

 rooted grinders, as P. ursimi and P. prohoscidea. In 1829, in the 

 article Zoologie in the ' Diet. Sci. Nat.' lix. 367, he divides them 

 into — 1. Les Phoques proprement dits, including the genera Callo- 

 c*phalus, Stenorhynchus, Pelagius, Stemmcdopus, Macrorhinus, Arcto- 

 cephaJus, and Platyrhynchus, and 2. Les Morses, for the genus Tri- 

 checus. In a paper on the genus, in ' Mem. Mus.' xi. 1827, 208, he 

 proposed to divide them into the following subgenera pin ced in three 

 sections ; — 



Skct. 1. Grinders similar, double-rooted. — 1. CallocejJmhis (vitu- 

 linus); 2. Stenorhynchus (leptonyx) ; 3. Pelagius (monachus). 



Sect. 2. Grinders simple-rooted ; ciitting-tceth ^. — 4. Stemmato- 

 pus (cristatus); 5. Macrorhinus (proboscidalis). 



Sect. 3. Grinders simple-rooted ; cutting-teeth I-. — 6. Arctocepha- 

 lus (ursinus) ; 7. Platyrhynchus (leoninus). An abstract of this 

 paper is given in Fischer, Syn. Mamm. 230, 



Mr. Josluia Brookes, in the Catalogue of his Anatomical and 

 Zoological Museum, 36, 1828, divides the Tetrapteryyia, or Seals, 

 into three families: A-iz. 1. Phocidce or Brachiodontia ; 2. Otariadie; 

 and 3. Trichechida' or Camp>odontia,
