DUBLIN KATUHAL UI8T0BT SOCIKTY. 43 



Palamon serrattts, — Very common. 

 P. squilla. — Very common. 

 P. Leachii. — Common in autumn. 

 Mysia vulga/ris. — Common. 



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

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

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

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

 the B^yal Dublin Society's Museum.

NOTES ON THE FOEEGOINO PAPER, WITH A SUPPLEMENT TO HIS LIST OP 

 DUBLIN CEUSTACEA. 



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 ad^g, at the same 

 time, a supplement of those eastern species (some of them of extreme 

 interest, and one oi H. puaiolay not previously here recorded), which 

 have occurred to me since. 



Although such a large number of Cnistacea (sixty-three out of 

 eighty-seven species) are recorded in this paper, yet, during a day's 

 dredging in Galway Bay on the 27th of March last, when in company 

 with Professor Melville, among twenty-two species which rewarded our 

 labours, three occurred which had not been previously met with there 

 by him, viz., Portuntcs hoUatus, and Pandalus annultcorms, and a young 

 specimen of Portunus marmorem, a species hitherto unrecorded save in 

 Birterbie Bay. 



DISTEIBUTION OF SPECIES NOT INCLUDED IN DUBLIN LISTS. 



References as in former paper — A. G. M., Professor Melville. 

 AcJuem Cranchii. — The only Irish specimen on record, formerly in 

 J. V. Thompson's collection, was lost previous to the transfer of that col- 

 lection to the Royal Dublin Society. 



Pisa tetraodon. — First discovered by "W. M'Calla. 

 ** I am the only person who as yet has found this species in Ireland; 

 ,it8 habitat is within two miles of Roundstone, in a pool at about half 

 ide-mark. As particular situations are distinguished by alg® growing 

 the pools, it may, therefore, be well to state the plants in that under 

 )nBideration : — Gelidium comeum, Poli/s./ruticosa, and Cy8tos,ericoides, 

 Iwing to changes in the pools, I have not lately obtained this species ; 

 have not found it in lobster-pots, and rarely under stones." — Saund^s*
