104 MAMMALIA. 



ing lines, which sometimes forms rinji^s — Ph. annellata, Nils., Thie- 

 nem., pi. ix — xii; Ph.foetida, Fabr*., &c. 



A species more easily recognised is the 



Ph. yroenlandica, and P. oceanica; Eged. Groenl. fig. A, p. 62; 

 Lepechin, Act. Petrop. I, part I. pi. vi — vii. ; Thieneman, pi. xiv 

 — xxi. (The Harp Seal). Yellowish grey, spotted with brown when 

 young, afterwards marked by an oblique black or brown scarf on each 

 flank ; tlie head of the old male is black ; length five feet. From 

 the whole north of the globe. 



Ph. barbata, Fabr. ; Thienem., pi. i — iv. (The Bearded Seal). 

 From the north, and surpasses all the preceding ones in its size, 

 which is from seven to eight feet : it is grey ; browner above, with a 

 longitudinal blackish line that forms a sort of cross upon the chanfrin. 

 Its mustachios are thicker and stronger than the others. 



Ph. leueopla, Thienem., pi. xiii. (The White-nailed Seal). Is 

 of a yellowish grey. 



Ph. Uujura, Cuv. (The Hare-tailed Seal). Has the tail white 

 and woolly, &c.f . 



Stenorhincus, Fred. Cuv. 



Four incisors above, and four below, the molars deeply notched into 

 three points. 



One species only is known, and that is from the Austral seas — 

 Ph. leptonix,^\'dm. Size of the barbata; greyish above; yellowish 

 beneath ; nails small. 



Pelagus, Fred. Cuv. 



Four incisors also, above ajid below, but their grinders are obtuse cones, 

 with a slightly marked heel before and behind. There is one of them in 

 the Mediterranean. 



Ph. monachus Gm.; Buff. Supp. VI. pi. xiiij. (The Monk). 

 From ten to twelve feet in length, of a blackish brown, with a white 

 belly. It is particularly found among the Grecian and Adriatic 

 Islands, and is, most probably, the species best known to the antients. 



Stemmatopus, Fred. Cuv. 



Four superior incisors, and two inferior; grinders compressed, slightly 

 trilobate, supported by thick roots. Such is the 



Ph. cristata, Gm. ; Phoca leonina, Fabr. ; Eged. Groenl., pi. vi. ; 

 Dekay, New York Lye. I, pi. vii. (The Hooded Seal). Seven or 

 eight feet long ; a piece of loose skin on the head, which can be in- 

 flated at the pleasure of the animal, and is drawn over the eyes when 



* It is one of those represented by Fr. Cuv. under the name oi " Plwque commun." 

 f I only wish to mention those species which I consider sufficiently ascertained. 



The long catalogues of the Phocae, recently published, seem to me to multiply them 



a great deal too much. 



X It is the same individual described by Hermann, Sec. des Nat. de Berl. IV. xii, 



xiii, under the name oi monarchus.
