The first specimens procured in this country were taken from the stomachs of cod-fish near 
Falmouth. The species was long previously known as inhabiting the Mediterranean Sea. ‘The 
general form is that of a shrimp, but in the front pair of feet the hands are enormously large and 
quite dissimilar in form and character, the larger having scarcely any hairs, but strong tubercles 
on the nippers, and the smaller having those organs lanceolate and hirsute.
