TECHNICAL HISTORY SPECIES. 443 



sent by M. Milbert to the Paris Museum from New York. The 

 author's remarks on the species of this group abound with ju- 

 dicious suggestions and form an important contribution to the 

 subject. He discusses at length the Plioca oceanica of Lepechin, 

 and refers it unquestionably to Plioca grccnlandica. 



Harlan, in 1825, in his "Fauna Americana" (pp. 102-112), 

 recognized five species, as follows : 1. Plioca crlstata ; 2. Phoca 

 cititUna; 3. Plioca grcenlandica; 4. Phoca fcetida; 5. Plioca 

 barbata. All are valid ; all stand under their correct specific 

 names ; the few synonyms given are all correctly referred ; and 

 only one species (Halichcerus grypus) known at that time to in- 

 habit North America is omitted. 



Godrnau, the following year (1826), in his "American Natural 

 History" (vol. i, pp. 310-346,) recognized also the same number 

 of North American species, and under the same names, but 

 gave a much more extended account of them. 



In 1826, in the article "Phoque," F. Cuvier gave, in the 

 " Dictionuaire des Sciences Naturelles" (vol. xxxix, pp. 540- 

 553), a systematic revision of the Seals, respecting which he 

 says, " Nous reuuirons done dans cet article, niais d'une niani- 

 ere fort succiucte, tout ce qui a rapport aux phoques consideres 

 comme ordre, cornme genres et coinrne especes." In this re- 

 vision he adopts the genera proposed by him two years ear- 

 lier (see antexi, p. 415), and recognizes the following species : 

 1. Callocephalus mtulinus ; 2. C. leporinus; 3. (7. discolor ( = 

 "Phoque comrnun," Hist. uat. des Mainin., 9 e livraison) ; 4. (7. 

 lagurus; 5. C. (jrcenlandicus ; 6. C. liispidus ; 7. C. barbatus ; 

 8. Stenorliynclius leptonyx ; 9. Pelagius monaclius ; 10. Stemma- 

 topus cristatus ; 11. Macrorliinus prol)oscideus. 



In addition, under the caption " Phoques privces d'oreilles ex- 

 ternes," he cites the following as too little known to enable him 

 to recognize their generic characters, explains the basis on 

 which each rests, and gives such brief notices of their charac- 

 ters as he was able to glean: 1. Phoca coxiij Desni. ; 2. P. 

 maculata, Bodd. ; 3. P. ?A7/fA-, Desrn.; 4. P. litpina, Molina; 

 5. P. byroni, "Blaiuv."; 6. P. aiisoni, u Blaiuv."; 7. P. oceanica, 

 Lepech. ; 8. P. tcstudinea, Shaw; 9. P. longicolliSj Shaw; 10. 

 P. fasciata, "Shaw"; 11. P. punctata, "Encycl. angl."; 12. P. 

 maculata, "Eucycl. augl."; 13. P. tiiyru, "Encycl. angl."; 14. 

 Phoquc tig-re, Krasch. 



Of the eleven species accepted as valid, two only (C. lepori- 

 nus and C. discolor) are nominal ; of the fourteen provisionally
