The district in which the subjoined species were captured extends 

 from Loop Head to Slyne Head ; including the bays of Galway, Round- 

 stone, and Birterbie, and the channels and seas adjacent to the isles of 

 r Arran ; many of the species from this latter locality were dredged from 

 a depth of sixty fathoms. To the species of but local occurrence the name 

 of the precise locality is appended ; with but very few exceptions, the 

 specimens were obtained in 1850, and specimens of most of the species 

 are to be seen in the Museum of the Queen's College, Galway.
