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

 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. Buifon 

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

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

 most naturalists have adopted this name. 



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

 Seals as forming an order, named yl«ip7H'6/«, containing two families : 

 Fhocadce for Phoca and Otaria, and Tricheddce for Tricliecus, 



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

 hydra), Seals (Phoca), Ursine Seals (Otaria), and Wakus (Tricliecus) 

 in a single group, which he called Palmata. — Phil. Zool. ii. 187. 



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

 into five tribes : — I. Phocce sine auriculis : Trihiis prima, P. vitu- 

 lina ; Tribus secunda, P, monachus ; Trihus tertia, P. mitrata ; Trihus 

 quarta, P. proboscidea, II. Otance (Phocce aunculatce) : Trihus 

 qtiinta, P. leonina, &c. 



In the ' Annals of Philosophy' for 1825, I considered the genera 

 Phoca and Trichecus as each forming a family, and proposed to 

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

 simple. 1. Stenorhi/nchi7ia,'Pe[agius and Stenorh}mchus. 2. Phocinu, 

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

 with distinct ears. 3. Eidii/drina, Enhydra. 4. Otariina, Otaria 

 and Platyrhynchus. 5. Stemmatopina, Stemmatopus and Macro- 

 rhinus. 



M. F. Cuvier, in 1825, in the ' Dents des Mammiferes,' 118, di\-ides 

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

 P. vitidinci; P. Leptomjx, and P. mitrata, and those with simple-, 

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

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

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

 cephcdxis, Sfenorhi/ncJms, Pelagius, Stemmatopus, Macrorhinus, Ai-cto- 

 cephcdus, and Phtz/rhi/nchus, and 2. Les Morses, for the genus Tri- 

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

 proposed to divide them into the following subgenera placed in three 

 sections : — 



Sect. 1. Grinders similar, double-rooted. — 1. CaUocephcdus (vitu- 

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



Sect. 2. Grinders simple-rooted ; cutting- teeth -|. — 4. Stemmato- 

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



Sect. 3. Grinders simple-rooted ; cutting-teeth .^.—6. Arctocepilui- 

 lus (ursinus); 7. PJati/rhynchits (leoninus). An abstract of this 

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



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

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

 into three families: viz. 1. Phocidce or Brachiodontia; 2. Otariadce; 

 and 3. Tricliechida'. or Gampodontia.
