than those whose engagements are seafaring. The splendid specimens 

 obtained by Professor Haughton in the Baltic belong to a species pecu- 

 liar to northern seas, which is allied to Oniscus or Idotea pelagica of 

 our coasts. It is figured in Pennant as the Idotea entomon, the Asellus 

 mci/rinus cornubiensis of Northern zoology. The singular feature is the 

 creature being found so abundantly attached to the timber and bark of 

 pines, which were sunk in hollows of deeper soundings in the Baltic. 

 The large and remarkable specimen exhibited was indeed singularly 

 characteristic of the Trilobite. 



The meeting then adjourned to the first Friday in June.

Occasional Notes on the Occurrence of Birds on the Shores of 



THE ElVER MOY AND KlLLALA BAY. No. III. By EOBERT "WARREN,

I have much pleasure in bringing under the notice of the meeting the 

 occurrence during the past season of the undermentioned rare birds, 

 viz. : — Ivory Gull (Larus eberneus) ; Iceland Gull {Larus Islandicus) ; 

 "White Curlew (JVumenius arquata) ; Black- tailed God wit (Limosa me- 

 in summer plumage. 

 On the 21st of last September I had the good fortune of meeting a 

 fine specimen of the Ivory Gull in a grass field near Killaney Church, 

 about a mile from the Eiver Moy. It was in company with some com- 

 mon Gulls (L. canus) ; and as they walked about the field quite leisurely, 

 and very tame, I had an excellent opportunity for observing it. The 

 bird was evidently in full adult plumage, as it appeared to be perfectly 

 snow-white. I regretted very much not having my gun with me at 

 the time, as I should have attempted to secure the bird for the Society's 

 collection. "William Thompson, in his work on the birds of Ireland, 

 speaks of the Ivory Gull as being very rarely observed, and he only re- 

 cords the capture of two specimens — one obtained near Dingle, county 

 of Kerry, by Mr. E. Chute, in February, 1847 ; and the second as being 

 picked up dead on the coast of Achill by a coastguard, many years be- 

 fore, but he does not give the date.
