DUBLIN NATURAL HISTORY SOCIETY. 153 



Munida Rondeletii. — Galway, rare. 



Palinurus vulgaris. — My experience of the occurrence of this species 

 would lead me to believe it rare here. 



Astaeus fluviatilis. — Rivers, common. 



Homarus vulgaris. — Yery common. 



Nephrops Norvegicus. — Rare. 



Crangon vulgaris. — Common, local. 



C. faseiatus. — Isle of Arran, rare. 



C. spinosus. — Isle of Arran, rare. 



C. sculptus. — Isle of Arran, rare. 



C. bispinosus. — Arran. This species, now first added to the Irish 

 list, and of extreme rarity in Britain, was established by Hailstone on 

 the authority of a single specimen ; several specimens occurred to me, 

 and there can be no doubt of its specific distinction from C. trispinosus. 



Alpheus ruber. — Isle of Arran, 60 fathoms. This species is now 

 first added to the Irish list ; the specimen is particularly interesting as 

 having been obtained in dredging. British specimens heretofore recorded 

 were all obtained from the stomachs of fishes. 



JVika edulis. — Roundstone, rare. 



Athanas nitescens, — Ballyvaughan, county of Clare. Under stones 

 between tide-marks ; common, but local. 



Hippolyte varians. — Rare. 



IT. Cranchii. — Common. 



H. Mitchelli. — Rare ; its first record as Irish ; this specimen was 

 obtained by me in 1850, and then laid aside as nondescript; it has 

 since been described from Weymouth under the above name by W. 

 Thompson. 



Palmmon serratus. — Very common. 



P. squilla. — Yery common. 



P. Leachii. — Common in autumn. 



Mysis vulgaris. — Common. 



Besides these, numerous specimens of the genera Alauna, Bodotria, 

 and Cuma have been met with. These genera, or at least Bodotria, are 

 synonymous with Scorpionura of J. Yaughan Thompson, as may be seen 

 by examination of the specimens under that name in his collection in 

 the Royal Dublin Society's Museum. 



Professor Kjnahan next submitted the following — 



NOTES ON THE FOREGOING PAPER, WITH A SUPPLEMENT TO HIS LIST OF 

 DUBLIN CRUSTACEA. 



The interesting paper just read contains several species not included in 

 either of the papers on this subject which I have had the honour to 

 submit to your Society during the present session. In order that our 

 Transactions for this year may contain all that is known of the distribu- 

 tion of this family of Crustacea in Ireland, I have supplied the distri- 

 bution of these species, taking the opportunity of adding, at the same
