gray to blackish dorsally, with sides paler and spotted with white. 

 Males have a bladderlike protuberence on the nose which they can 

 inflate in times of anger or danger. 



Maryland records, — One recorded in 1865 as taken near Cambridge, 

 Dorchester County, on an arm of the Chesapeake Bay, 18 miles from 

 salt water (Cope, 1865, p. 273) ; one animal killed at Worton Point, 

 near Chestertown, Kent County, about 1860 (Mansueti, 1950, p. 31). 



It is possible that the seal from Tangier Sound previously listed as 

 Phoca mtulina concolor may have been a hooded seal rather than a 

 harbor seal. The Baltimore Sun of 9 July 1898, which reported the 

 killing of the animal on 8 July 1898, said that it measured almost 6^/^ 

 feet in length. If this measurement was accurate, the animal would fall 

 within the size range of the hooded seal rather than the harbor seal. 



Order CETACEA (cetaceans) 



The order Cetacea is divisible into two distinct suborders distin- 

 guished primarily by the presence of teeth, or baleen in the mouth. 

 Those that are toothed are classified as : 



Suborder ODONTOCETI (toothed whales) 



Toothed whales may have teeth in the lower jaws only, or in both 

 upper and lower jaws. In some forms more than 100 teeth are present, 

 while in others the teeth may be reduced to 2. Whales of this suborder 

 never possess baleen.
