442 FAMILY PHOCID.E. 



genus Callocephalus. He discusses to some extent the charac- 

 ters of several of the species of Earless Seals (as well as Otaries) 

 and figures the skulls of five of them. 



The same year (1824) Thienernann * published his observa- 

 tions on the Seals collected and observed by him in Iceland, 

 in which he renamed most of the species, and published a full 

 description and colored illustrations of the animals, and figured 

 the skulls of most of them. He recognized seven species, which 

 are as follows, with the allocations usually assigned them by 

 recent authorities : t 1. Plioca littorea (= P. vitulina); 2. Phoca 

 (imidlata (= Phoca fcetida) ; 3. Phoca grcerilandica; 4. Phoca 

 harbnta; 5. Phoca halichoems (= Hali cheer tis grypus) ; G. Phoca 

 scopulicola ( = Halichoerus grypm, young); 7. Phoca leiicopfa 

 (= Cystophora cristata). Of these seven species two are purely 

 nominal, and three others represent species previously de- 

 scribed. Thieneiiiarm here adds in all four synonyms and no 

 new species.:}: 



G. Cuvier, in his "Ossemens fossiles", gave a somewhat 

 extended but informal review of the " Phoques vivantes," in 

 which are described two new species, namely, Phoca lagura 

 (= Phoca yrcenlandica, young), from " Terre-Neuve," received 

 from M. de la Pilaye. It is evidently based on a quite young 

 animal, having a length of "trois pied trois ponces," and cov- 

 ered with "laine blanche". He also describes a Phoca mitrata 

 (ex "Camper" MSS.)|| based on a skull of Cystophora cristata

|| The name mitrata, derived from the same specimen, appears to have 

 been previously made public by Desmarest in 1820, who says "M. Milbert, 

 correspondent du Museum, dans les fitats-Unis, vient d'envoyer a cet e"tablisse- 

 ment, sous le noni de Phoca mitrata, la tete d'un phoque qui diff'ere essen-
