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. Sj^mphysis of the lower jaw short. 



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

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

 a small nearly terminal claw. The hind limbs arc 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 Cu-vier, erroneouslj' 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 . t§=32 : the two lower middle 

 incisors peculiar. Vertebras : — 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 exti'cmities 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 Fucus ; thousands of a small, hard, 

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

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

 9 lines : diameter of smaU 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 oft' an extremely short 

 mnominata, which divided it into a right carotid and subclavian, 

 and left carotid ; the left subclavian came oft" separately. It resembles 

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