DUBLIN NATUKAL UI8T0BY 80CIKTT. 31 



monograph of the Irish species of this geniis, at present in preparation, 

 and, therefore, will not now notice it further than as follows : — 



Paoueus Eblanensis {niihi) (? Bernhabdus). 



Resemhling young of P. BernharduH. Hands more regularly globular, 

 very granular; a raised denticulate line marking exterior edge; terminal 

 extremities of posterior pairs of legs scarcely twisted ; colour, reddish- 

 white ; legs prettily banded with reddish pink. 



Among the Crustacea obtained at Dalkey Sound, I find specimens 

 of a very remarkable form of Porcellana, exhibiting peculiarities hitherto 

 undescribed, and which appear specific, the same form having occurred 

 to me at Rush. It seems as well to notice it ; and I propose, should 

 it prove distinct, to call it Par cellana priochelea (mihi) (-jr^ttft ;^i)Aii). 



Sehbate-clawed Poecelain Cbab. 



Allied to P. longicomis. The anterior pairs of legs nearly equal ; 

 both hands furrowed, scabrous ; exterior edges finely but distinctly ser- 

 rated denticulate in arm, with ternal margin produced ; broken up into 

 lobes ; front produced, finely denticulate, indistinctly four-lobed ; sides 

 of carapace armed with a number of teeth (?). 



Colour : Pale-red, with blotches and patches of white. 



Habitat : Rush ; Dalkey Sound. 



I have great doubt whether this is not merely a young form of 

 P. longicarnis. 



In conclusion, I have to lay before your Society a list of species ob- 

 tained on the Dublin coasts, additional to those noted by me in a paper 

 on the ** Crustacea of Valentia Island" (p. 62), as in that paper it only 

 contains those noted by myself, with a single exception. Several more 

 species have occurred. The references used are the same as in my pre- 

 vious paper, and I have omitted the species there noticed.

 nuirostria.
