pretty Eolis — called after Dr. Farran, the well-known naturalist of this 

 city — and of which but a single specimen had occurred to its discoverer 

 (Mr. Alder), at Malahide, had been found, all along the south coast, in 

 tolerable plenty ; at Parkmore Head, near the entrance to the lovely Bay 

 of Ventry, a spot abounding with interest to the zoologist, and classic 

 ground to the antiquarian; and, not very far from the ruins of the ancient 

 city of Faghan, I found numbers of this Eolis browsing on large meadows 

 of the well-known Hydrozoon, Tuhularia indivisa. 



At Castlehaven, in Cork Harbour, Professor J". Reay Greene disco- 

 vered a specimen of Boris flammea. This is one of the most brilliantly 

 coloured of the genus. It was first, I think, discovered by Professor E. 

 Forbes in the JEgean Sea, then it was found on the south coast of 

 England, and is now, for the first time (if I except the ''Report on the 

 Marine Fauna of the South and West of Ireland," presented at the Leeds 

 Meeting of the British Association) recorded as Irish. 



The two Hermaeas described in Alder and Hancock occurred very fre- 

 quently on the west coast, — Hermcea lijida, {requentrngGriffithsia setacea, 

 and JT". dendritica, Codium tomentosum, the leathery fronds of which 

 latter seem often quite covered with the little slug. 



It will be recollected that I by no means wish this list to be supposed 

 to represent the state of our Fauna, feeling quite certain that many more 

 species wait only to be recorded ; and as I have been unable to get con- 

 tributions to the list from any local collectors, I doubt not but that they 

 may have discovered other species, though I am not aware that they have 

 recorded them. 



For the advantage of any of our young members who may be induced 

 to study these creatures, I may, in conclusion, add, that Great Britain 

 produces few better collecting grounds than Malahide Bay, and that 

 Alder and Hancock's beautiful monograph will give them every requi- 

 site assistance.
