PROCEEDINGS OF SOCIETIES. 
Dr. J. R. Kinahan read a paper— 
ON THE OCCURRENCE OF A NEW IRISH .ESOP PRAWN (PANDALUS), IN DUBLIN 
BAT. 
But one species of the genus Pandalns of Leach has been hitherto recorded 
in Ireland. Last July (1857), I met a specimen which appears to be 
entitled to specific distinction: it occurred to me in a small sandpool in 
the zostera bank at Sandycove, Kingstown. The shape of the beak is 
remarkably dissimilar from that organ in P. annulicornis, being much 
shorter in proportion to the length of the animal, rounded instead of 
compressed at the sides, wanting the membranous dilatation on the under 
edge outside the eye, and hence, much shallower, and differently 
armed. It differs from the only other described form, P. narwhal, in 
having the superior anterior half of the rostrum free from spines or teeth. 
A third species has been recorded, but only a figure of it published by 
C. Spence Bate, E.L. S., in the “Natural History of Swansea,” published 
in the “Reports of the Swansea Literary Society,” under the name of 
P. Jeffreysii. I was at first inclined to consider my specimen this species, 
but an examination of specimens kindly furnished me by its describer, 
C. Spence Bates, led me to doubt the correctness of my first belief; that 
gentleman also appears to doubt it. I deem it better, then, to describe 
mine, provisionally only, under that name, at the same time suggesting 
the name P. Peptorhynchus, should mine prove distinct. 
P. Jeffreysii (Spence Bate), according to a communication of his to 
me, is tolerably common in Scotland. The original specimens were taken 
in Oxwich Bay, Swansea; they were two in number, but imperfect at the 
time figured. They were described at the British Association Meeting 
at Edinburgh, but only the name published. Mr. Spence Bate has also 
taken it at Plymouth, and has received it from the Rev. Mr. Gordon, of 
Moray Erith, as a new species. Some of the specimens from thence have 
only seven teeth above and two below, instead of eight above and two 
beneath, which is the usual number. 
The specimen now described approaches closely Uippolyte panda- 
Uformis, and affords another proof of the close affinity of the genera Pan- 
dalus and Hippolyte.
