 themselves. 



The existence of a sense corresponding to that of

 a sense resides it is difficult to give any satisfactory 

 opinion) may be inferred from the fact, that if, in 

 any locality frequented by these creatures, a dead fish,

 scavengers, whose knowledge of the whereabouts of 

 such a booty could only be derived from the effluvia 

 of putrefaction emanating therefrom. 



Among these littoral crustaceans, a very curious

 holes which it forms in the mud ; and against this we 

 specially warn our readers. It carries on a perpetual 

 warfare against the Nereids, the Amphinomes, the 

 Arenicolse, and other marine Annelidans which make 

 their dwelling in the same localities. There is nothing
