Bays and in Kinsale Harbour ; also on the fronds of Lami- 

 narta saccharina in Clifden Bay. 



We can scarcely doubt that this genus is identical with Dr. 

 Philippi's Euryte ; but, considering the somewhat vague de- 

 finition and figures given by that author, we should not feel 

 safe in discarding M. Boeck's more recent generic name. 



Genus Oithona, Baird. 



Oithona helgolandica?, Claus. 



Of not uncommon occurrence in surface-net gatherings :

 described forms. 



Fam. Harpactidae. 



Genus Longipedia, Claus. 



Longipedia coronata, Claus. 



In rock-pools, Great Isle of Aran ; and on Laminarioz in 

 Clifden Bay, where it was also dredged on a gravelly bottom 

 in a depth of four fathoms.

 In rock -pools, Great Isle of Aran.

 breves, tenues, articulo tertio appendicem gerentes ; antennae 

 posticse ramo secundario prseditse. Partes manducatoriae omnes
