Clare Island Survey — Amphipoda. 42 3 



Lysianassa ceratinus (Walker). 



Blacksod Bay and inlets, taken on nine occasions, shore to 5 faths. lnish- 

 lyre Harbour, 5 faths., and surface, two. Off Clare Island, 7-17 faths., two. 

 Bofin, common. BaUinakill Harbour, common. 



Previous Irish Records : — Strangford Lough, Clew Bay, Valentia. 



Distribution : — Atlantic coasts of Great Britain, Ireland and France. 



I have accepted Chevreux's decision, that this species is distinct from 

 L. longicornis Lucas, with which it has been united by Stebbing. I have seen 

 over one hundred specimens of this species, and they all, without exception, 

 have the hind margin of the third segment of the metasome rounded. None 

 of them shows any approach to the spiniform condition seen in I. plumosa 

 Boeck. It is quite the most abundant Lysianassid in shallow water on the 

 West of Ireland. 



Perrierella audouiniana (Bate). 



Blacksod Bay, 5 faths., two. Inishlyre Harbour, 5 faths., two. Fahy 

 Bay, BaUinakill Harbour, 3 faths., sixteen. 



New to Ireland. 



Distribution: — North Atlantic and North Sea from Norway to France, 

 Mediterranean. 



Orchomene batei G. 0. Sars. 



Blacksod Bay, 1-8 faths., common. Outer Harbour, Bofin Island, one. 



Not certainly recorded from Ireland before, though it is probable that 

 Thompson's records of Anonyx elegans from Bangor, Co. Down, and Kinahan's 

 of Anonyx minutus from Belfast Lough refer to this species. 



Distribution : — North Atlantic and North Sea from Norway to France, 

 Mediterranean. 



Ichnopus spinicornis Boeck. 



Off High Island, Co. Galway, surface, one. 



New to the district. 



Previous Irish Record: — Off Valentia (Porcupine). The present record 

 is only the second one for the British Isles. 



Distribution : — Arctic Ocean, North Atlantic and North Sea, Mediterranean 

 and Java Sea.

1| miles E.N.E. of Clare Island light, 21 faths., eleven.
