PALJiMONlD.E. 



This species is less widely distributed, as far as we can 

 at present judge, than either of the former ones. It is, 

 however, found on the Devonshire and Dorsetshire coast, 

 and onwards as far as that of Norfolk. Mr. Couch does 

 not include it in his Cornish Fauna. Mr. Thompson states 

 that a few specimens have been taken in Belfast and 

 Strangford Loughs, and I have received it myself from 

 Ireland through the kindness of Col. Portlock. 



The vignette consists of several variations of the rostrum 

 in three species of Palsemon. The first three on the left 

 are of P. Squilla. The three in the middle belong to P. 

 serratus, and the three on the right to P. Leachii.
