Walrus.- — The walrus here shown is the Atlantic 

 species. JSTote in the skeleton that the long tusks are 

 the greatly enlarged upper canines, the incisors being 

 wanting. These the animal uses in digging up mus- 

 sels and to assist in climbing apon the ice, or on the 

 land. The walruses are closely related to the seals 

 just described. Ranging up to 12 feet long, they 

 weigh from a ton to a ton and a half. Less closely 

 related are the three other forms in the Museum, 

 which are known as the earless seals. The little one 

 in the case with the polar bear is the common harbor 

 seal. It was captured in the harbor here, a fact of 

 interest since it had not before been found so far 

 south. 



Seal. — The harp seal is more strictly northern in, 

 range. These ? as are the harbor seals, are much 

 hunted for their skins and oil, though they do not have 

 the fine soft coat of underfur that gives the fur seal 

 its great value. 



Seal. — The hooded seal in the lower case south of 

 the steps to the gallery may be mentioned here. They 

 are readily distinguished by the large movable mus- 

 cular bag on top of their heads. The hood is found 

 only on the male. Like the last it is an Arctic spe- 

 cies. They are from 6 to 8 feet long and will weigh 

 from 500 to 900 pounds.
