Atlantic. A closely allied form is found in the North Pacific ; 

 which, indeed, may be identical. The lesser rorqual also feeds 

 on small crustaceans and tiny fish. 



The remains of fossil whales related to the rorquals, as well 

 as others closely allied to the right whales, are found in some 

 abundance in the Eocene formations of East Anglia ; perhaps 

 also of Hampshire, in which county remains of the archaic 

 Zeuglodonts {^Archeeocett) have been discovered. From these 

 remains in England and Belgium, it would almost seem as 

 though the North Sea at one time was a great area of develop- 

 ment and radiation for the Mystacoceti, or whalebone whales, if 

 not, indeed, for the whales generally.
