132 DUBLIN NATURAL HISTOBY SOCIETY. 



Anonyx minutus. — Cod's stomach, Belfast ("W. T., S. B.). 



Ampelisca typicm. — Belfast Bay ("W. T., S. B.). Extremely common 

 on the north scallop bed, Kish Bank, Dublin. 



Ampelisca Belliaiius. — Newcastle ; Down (W. T., S. B.). 



Westwoodea cacula.—(W. T., S. B.) ? Belfast. 



Iphimedia ohesa. — By no means rare ; Belfast Bay ("W. T., S. B.). Dub- 

 lin, Bray, common. 



Dexamine spinosa. — Extremely common both in dredge and rock-pools ; 

 in the former particularly you generally meet ten of this Amphipod 

 for one of any other. This species occurs in the Thompson list, but 

 it were wasting space to detail localities. Dublin, Kish, and Sandy- 

 cove, very abundant. 



Dexamine hispinosa. — Bangor, county Down (W. T., S. B.). I have 

 never met this species in Dublin, though I have looked carefully for 

 it. 



Gamma/rm locusta. — Common here, as everywhere. Dublin. 



Gammarus fluviatilis. — Eresh-water streams near Carrickfergus. Very 

 common in Dublin. Careful comparison of specimens taken by me 

 in "Waterford, Clare, Dublin, Tyrone, &c., has resulted in the con- 

 clusion that but one species of fresh- water Gammarus occurs in Ire- 

 land. The record of Gammarus pulex — i. e. a species with the 

 posterior angles of the abdominal rings produced as teeth — has 

 arisen, I believe, from W. Thompson having used this term as ap- 

 plied to G. fluviatilis of Eoesel in his early correspondence. The 

 true Gammarus pulex has not, I believe, been found in Ireland. 



Gammarus gracilis. — Bangor, county Down (W. T., S.B.). 



Gammarus marinus. — Carrickfergus, under the Castle; ''l^ewcastle, 

 Down" (W. T., S. B.). 



Gammarus palmatus, — This species, new to the Irish lists, occurred to 

 me in numbers at the bathing-place between Cultra and the railway 

 station. It occurs under stones covered with ente;romorpha and ulvse, 

 in a spot where a number of small sand-pools break a muddy sand- 

 beach. I had previously met the species in 1856, near Merrion, 

 county Dublin, in a similar locality. Spence Bate informs me it is 

 extremely rare in England, and certainly Montague's species. 



Gammarus Othonis. — Bangor; Belfast Bay (W. T., S. B.). 



Gammarus longimanus. — Carrickfergus. Rare, under the Castle. 



Amphitoe ruhricata. — Bangor (W. T., S. B.). 



Amphitoe littorina Newcastle; Bangor, county Down fW. T., S. B.). 



Howth, coxmty Dublin, extremely common. 



Corophium longicorne. — Clay, near ship-yard, Carrickfergus. Occurs in 

 hundreds on the muddy shores of the tidal portions of the Dodder, 

 county Dublin. 



Hyperia Galha. — In thousands in Acalephse, floating through the Bay; 

 in many instances as many as thirty or forty specimens could be ob- 

 tained from a single Acaleph ; many of the specimens taken had ova 

 attached to them.
