PLATE LVI. 



This large and interesting species of Balani is found adhering to 

 the Whale, whence it is called the Whale Acorn Shell. It is not 

 uncommon in the sea round Scotland. The natives of some of the 

 Western Islands distinguish one species of Whale from the rest, for its 

 great size, and the big limpets growing on their backs *. The 

 same species is common on the Whales in the Northern Seas about 

 Newfoundland. 



The Animal is figured by Ellis, in the Philosophical Transactions 

 for 1758, and resembles a cluster of small hooded and eared serpents 

 issuing from the central cavity, and little openings at the tops of 

 the longitudinal ribs. The base by which it is affixed, when alive, 

 is covered with a coriaceous skin.
