Devonshire and Ireland, in the Pinna ingens and in Mo-

Both male and female are brown. This is the species 
found in the Mediterranean, and whose history, mingled with 
much fable, is recorded by some of the ancient authors. 
In the poet Oppian* the story of the Pinnotheres is 
recorded according to the ancient belief of its life and 
manners. We quote the translation of this story given by 
Pennant. 
“ In clouded deeps below the Finna hides.

He forms no bait, nor lays the tempting snare ; 
But the dull sluggard boasts a Crab his friend. 
Whose busy eyes the coming prey attend : 
* Halieut., lib. ii., quoted by Pennant, Brit. Zool. iv. p. 2.
