specimens of the translucent and almost invisible C3-dippe. 

 We soon found that the only way to work on board the " Emma 

 Mary " with any approach to comfort was to stand in the 

 hold, and, with half the hatches off, explore the jars and 

 pans placed on the deck. In weather such as we had this day 

 it was easier to take in a sleeve full of water from the rolling 

 milk-pan than to catch one of its elusive population of 

 Cydippes. 



Jell3'-fisli large and small frequently wobbled past our boat. 

 We caught a few and found them to be Pilevia octopus^ a species 

 very common in Dublin waters. All the larger examples 

 captured carried in their pouches that well-known commensal 

 amphipod, the green-eyed Hyperia galba. A scrape of the 

 dredge in about six fathoms a mile north by east of Kingstown 

 Harbour gave us many large living specimens of Scaphander 

 lignarmSj with abundance of living Nucula nitida, and three 

 live specimens each of Lacima crassior and Odostomia rufa. 

 Along with these were dead ^yid.\\v^\^soi Montacuta ferruginosa 

 and M. bidentata. 



Failing to work across the bay to Howth Head, we put about 

 and crept down towards Dalkey Island. A slight freshening 

 of the breeze enabled us to make a couple of runs of the beam 

 trawl, and these yielded one specimen of Sepiola atlantica and 

 two of ^olis tricolor^ the nudibranch we had added to the 

 Dublin marine fauna on our previous trip. From a depth of 

 eight fathoms off Bullock the dredge brought up a large spray 

 of Ante7imdaria raviosa bearing numerous spawn coils of a 

 nudibranch, and close examination of the hydroid was re- 

 warded by the capture amongst its roots of eight live specimens 

 of Doto coronata harmonizing perfectly in colour with their 

 host. 



Jui^Y 31. —Starting from Bullock Harbour in a row boat, 

 Messrs. Butler and Colgan did some shore-collecting at low 

 water between Dalkey Island and the adjacent islet known as 

 the Lamb, and then dredged along Dalkey Sound and out into 

 Killiney Ba3^ The shore-collecting yielded little of interest 

 beyond one large specimen each oi ^olis papulosa and Doris 

 tuberc7ilata. Two scrapes of the dredge in nine fathoms 

 between Bullock and the northern end of the Sound gave us 

 53 species of Mollusca, amongst them the following; —
