DECAPODA. aOl 



Genus Athanas. 

 A. nitescens, Leach. 



A single specimen was found under a stone between tide-marks at 

 Lahinch, County Clare, by Prof. Forbes and myself in July, 1840. 



Genus HippoLYTE. 

 H. varians, Leach, 



Is an inhabitant of deep water around the coast. Mr. J. V. Thompson's 

 collection contains Lish specimens. This species has been dredged in 

 Belfast and Strangford Loughs, by Mr. Hyndman and myself, and was 

 similarly procured by our party in July, 1840, in Clew and Roundstone 

 Bays, on the western coast. Li Dalkey Sound, Dublin Bay, an H. va- 

 riatis ? was taken by us in the dredge. 



H. Crnnchii, Leach, 



Is marked in Mr. J. V. Thompson's collection as Irish. 



H. Tliompso7ii, Bell. 



N. W. coast of Ireland, AV. T. 



Genus Pandalus. 

 P. annulicornis, Leach, 

 Is in Mr. J. V. Thompson's collection. The species has been taken com- 

 monly by Mr. Hyndman and myself in the rock-pools accessible at low- 

 water throughout the Down coast, and has been dredged by us in deep 

 water on the North-East coast, and in Killery Bay, Connemara. Dr. Ball 

 has specimens from the shores about Dublin. 

 Dredged off Donaghadee, Dr. Drummond. 



Genus Pal.emon. 

 P. serratus, Leach. 

 The praAvn, an article of human consumption, is noticed in some of our 

 old County histories, as Harris's DoAvn, Smith's Cork and Waterford, 

 Rutty's Dublin. The last author says, apparently * with reference to this 

 species, that " it was formerly frequent on our coast, but the frost in 

 1740 destroyed many of them"! vol. i. p. 379. Templeton speaks of it 

 as " once common in Belfast Lough ; now rare." Some years ago I ob- 

 tained from this locality a very large specimen, which was taken in a lob- 

 ster-pot at the entrance of the bay. Here the species has more lately 

 been obtained by the collectors attached to the Ordnance Survey, who 

 likewise procured it at Portrush near the Giant's Causeway. Dr. Ball 

 states, that at Youghal prawns are taken only during the ftrst quarter of 

 flood-tide, and then plentifully : at the South Islands of Arran he cap- 

 tured numbers of them in the summer of 1835, and out of about fifty, 

 found three with Bopyri attached. — See Annals, vol. v. p. 256. 



P, Squilla, Leach. 



Templeton notices this sj^ccics as " common on the shore of Belfast 

 Lough." It is of frequent occurrence in rock-pools throughout the range 



* He refers to Roiicleletius for the species meant, a work ^^■hich I have not 

 al present to consult.
