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

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



Pagitrtjs Eblanensis (mihi) (? Bernhardus). 



Resembling young of P. Bernhardus. 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 Porcellana priocheles (mihi) (jrg**i #»*»)). 



Serrate-clawed Porcelain Crab. 



Allied to P. longicornis. 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. longicornis. 



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 Yalentia Island" (p. 62), as in that paper it only 

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

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

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



LIST OF SPECIES. 



W. T., Thompson's Irish Fauna; J. Y. T., J. V. Thompson's Collec- 

 tion; C. C.S., Catalogue of Cork Fauna; 0. C, Ordnance Survey Col- 

 lection ; W. M'C, collected by ¥m. M'Calla. The localities uninitialled 

 are on my own authority. 



Stenorrhynchus phalangium. — Common laminarianto coralline zones; 

 sometimes thrown ashore ; specimens dredged in deep water agree with 

 the details of a form described by Wm. Thompson as a form of St. te- 

 nuirostris. 



Belfast (W. T.), Dublin, Cove (J.Y. T.), Dingle (W. Andrews, Esq.), 

 Galway, Killeries (W.T.). 



Inachus dorynchus. — Not uncommon; Malahide, Dalkey, same range 

 as last. 



Belfast (0. C), Dublin, Galway, Roundstone (W. M'C). 



Inachus Dorsettensis. — Rarer than I. dorynchus. 



Belfast (W.T.), Dublin Bay, Cove (C.C.S.), Roundstone (W.M'C.), 

 Killeries (W. T.).
