This enormous animal fully equals, if it does not indeed 
exceed in bulk, the Greenland, or Right Whale. Specimens 
taken in this country have exceeded 100 feet in length, and one 
captured in 1831, near our own coast, measured 80 feet in length. 
Its Norwegian name, Rohr-waale, from whence comes our 
Rorqual, signifies the ‘‘ whale with folds,” from the Plicz on the 
anterior ventral surface.
