16 PHOCID^. 



single thick conical root; all the rest have two rather diverging 

 roots, divided nearly to the crown ; the hinder tooth in each jaw is 

 rather the smallest. Symphysis of the lower jaw short. 



Body tapering behind. The fore Umbs moderate, rather elongate ; 

 the toes are rather larger than the wrist, and each furnished with 

 a small nearly terminal claw. The hind limbs are rather large, of 

 two nearly equal lobes, destitute of any claws; the three middle 

 toes small, tapering. 



The fur close-set, short, without any under-fur ; hairs flattened, 

 tapering at the tip to a point. 



In the young skuU the grinders are well developed, while the 

 cutting-teeth are small and far apart ; the hinder grinders have four 

 lobes where they have only three in the adult. 



Mr. MacMurtrie, in his translations of Cuvier, erroneously adds to 

 the generic character in the text of the author, " but with single 

 roots ;" this is repeated in the reprint of the American edition pub- 

 lished by Orr, i. 98. 



Dr. 'Knox, observes, " Teeth, |- . f . -j4=32 : the two lower middle 

 incisors peculiar. Vertebrae : — cranial, 4 ; cervical, 7 ; dorsal, 14 ; 

 lumbar, 6; sacral, 3; coccygeal, 13=47. 



" The nostrils opened much after the manner of the Cetacea, in 

 the form of elongated fissures, one inch from the extremity of the 

 snout ; the pelvic extremities very large and far back ; tail extremely 

 short. The skin was hairy. The stomach contained numerous fish- 

 bones, a few feathers (gulls'), and some considerable portions of a 

 pale-green, broad-leaved, marine Pucus ; thousands of a small, hard, 

 round, white worm (parasitical) pervaded all parts of the Lntestines. 

 The intestinal tube measured 71 feet 10 iuches : caput caecum, 1 inch 

 9 lines : diameter of small intestines, 1 inch ; of large intestines, 1 inch 

 6 lines. Liver weighed 14 lbs. ; kidneys, 2 lbs. each ; spleen, 1 lb. ; 

 heart, 6 lbs. The arch of the aorta gave off an extremely short 

 innominata, which • divided it into a right carotid and subclavian, 

 and left carotid ; the left subclavian came off separately. It resembles 

 Tiedemann's third variety, pi. 3 (copy published in Edinburgh)."
