Decapod Crustacea of Bermuda, Part II. 13 



The densely haired extremities of the legs give those appendages 

 a remarkable appearance. The hairs are evidently sensory and 

 may be of use. in collecting small organisms for food. Mr. Louis

 legs are constantly used for cleaning various parts of the body, and 

 seem also to be of great use in enabling the creature to creep softly

and quietly over the bottom in search of its prey. He states that 

 he has seen it seize and devour a "hind-fish" six inches long, as
