The greater number of species in the first and fourth localities as 

 compared with the second and third is probably due to the long-continued 

 and systematic collecting carried on by the Fisheries officers at Blacksod 

 and Ballynakill. I now proceed to give a systematic list of the species, 

 with a few topographical and bionomic notes. The generic nomenclature of 

 Norman (3) has been followed. 



NYMPHONIDAE. 



Nymphon gracile (Leach). 



Blacksod (Feorinyeeo Bay, shore), Clew Bay (May, 1910),Inishbofin (Bonn 

 Harbour), Ballynakill (Coastguard Bay and Deep, 1-8 fms.) — (see 1, 2). 



Adults of this handsome species are most frequent in the spring months 

 (March and April). 



The synonymy of this species has been elucidated by Norman (3), who 

 has shown the identity of Leach's types in the British Museum with N. 

 gallicum of Hoek. It is a West Channel species, ranging northward along 

 our west coast to Killala Bay. In the Irish Sea it is scarce, but I have 

 examined specimens from Larne Lough and Malahide inlet. 



PALLENIDAE. 



Pallene brevirostris, Hodge. 



Ballynakill (Coastguard Deep, 6-8 fms., see 2. Fahy Bay, one male at 

 surface, 21st March, 1902). 



This, though it occurs both on our east and west coasts, seems to be a 



distinctly rare species in Irish waters. It has a very wide range abroad, 



having been dredged off the south-west coast of Norway, in the North Sea, 



English Channel and Mediterranean, and off the coast of Connecticut, North 



America. 



Phoxicbilidium femoratum (Bathke). 



Blacksod (Elly Bay, south shore, one female, 25th September, 1911). 



This is also a scarce species, though occurring on both our east and west 

 coasts. From the distribution as given by Norman (3) it seems to belong to 

 the northern faunistic group. 



Anaphia petiolata (Kroyer). 



Clare Island (3| miles S.E. of lighthouse, 13-16£ fms., 26th May, 1909, 

 two females). Clew Bay (south of Mulranny Pier, 5-11 fms., 26th May and 

 23rd August, 1909, two females). Inishbofin (2). Ballynakill (2), many 

 specimens.
