DECAPODA.

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. 
II. varians , Leach, 
Is an inhabitant of deep water around the coast. Mr. J. V. Thompson’s 
collection contains Irish 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. In Dalkey Sound, Dublin Bay, an H. va- 
rians f was taken by us in the dredge. 
H. Cranchii , Leach, 
Is marked in Mr. J. Y. Thompson’s collection as Irish. 
II Thompsoni, Bell. 
N. W. coast of Ireland, W. 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 prawn, an article of human consumption, is noticed in some of our 
old County histories, as Harris’s Down, 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 first 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 species 'as “ common on the shore of Belfast 
Lough.” It is of frequent occurrence in rock-pools throughout the range 
* He refers to Rondeletius for the species meant, a work which I have not 
at present to consult.
