Clare Island Survey — Marine Isopoda and Tanaidacea. 43 3 



Fam. Gnathiidae. 



Gnathia oxyuraea (Lilljeborg). — Very common in dredgings from Bonn and 

 Ballynakill Harbours. The larvae are frequently taken in tow-nets at 

 night and attached to the fins of fishes such as Coalfish, Pollack, Gurnard, 

 and White Trout. Off Ardelly Point, Blacksod Bay, in one fm., two 

 male specimens. 



Following Sars, I named this species 6-nathia inaxillaris (Montagu) in 

 my former paper. Norman has shown, however, that G. maxillaris is 

 quite a different species, and that the species so named by Sars must 

 bear the name here given to it. 



Fain. Cirolanidae. 



Cirolana borealis, Lilljeborg. — Not rare in the sand of Coastguard Bay, 

 Ballynakill Harbour, from which specimens may be dug at low-water, 

 spring tides. | mile S. of Mulranny Pier, Clew Bay, 8 fms., two 

 specimens. 



Conilera cylindracea (Montagu). — One mile N. of Cleggan Head, 19 fms., one 

 specimen. 



Eurydice pulchra, Leach.— Achill Sound, surface tow-net, one specimen. Bonn 

 Harbour, surface tow-nets, on three occasions. Elly Bay, Blacksod Bay, 

 one specimen dug from sand at low water, and two from a surface tow- 

 netting. 



E. spinigera, Hansen. — Ballynakill and Bofin Harbours, single specimens 

 occasionally in surface tow-nets. 



E. truncata (Norman). — Ballynakill and Bofin Harbours, very common in 

 surface tow-nettings. 1\ miles N.N.W. of Corwell, off Crump Island, 

 Co. Galway, 24 fms., one specimen. 



Fam. Limnoriidae. 



Limnoria lignorum (Bathke). — Found boring into the bottoms of two hulks 

 moored in Ballynakill Harbour, and also attacking wooden stakes at low 

 water. 



Fam. Sphaeromidae.
