the upper jaw, and four in the lower. O. Fabricius and Cuvier describe only 
four in either jaw ; but Muller (Prodromus) mentions having seen a Green- 
land specimen with five in the upper. The eyes are prominent, rather than 
sunken, as stated by Pennant. It might also be erroneously inferred that 
the walrus has a tail, from an expression in the Arctic Zoology, “ body very 
thick in the middle, lessening gradually towards the tail” 
12. Monodon Monoceros. Narwhal. 
An individual of this species was killed in Prince Regent’s Inlet; the 
horn was unfortunately not perfect, a piece having been broken off the end 
by some accident ; the part which remained was above four feet in length 
externally, the diameter at the insertion an inch and six-tenths, and at the 
broken end eight-tenths of an inch ; the length of the animal from the 
insertion of the horn to the fork of the tail, thirteen feet five inches and 
a half ; the spiracle at the summit of the head, fourteen inches and a half 
from the extremity of the snout, two inches eight-tenths in diameter, having 
a membrane in the interior, dividing it into two parts ; the fins were two 
feet four inches and a half from the insertion of the horn, six inches and 
a half broad at the base, seven inches and a half in the middle which is 
the broadest part, and fifteen inches long; the skin half an inch thick, 
marbled black and white in the back, beneath white ; the fins black. 
Besides the twelve species of Mammalia which have been thus described, 
the, Balaena Mysticetus, B. Physalus, and the Delphinus Albicans, were fre- 
quently seen, but no individual of either species was killed.
