370 CRUSTACEA, 



Genus Inachus. 

 /. Dorseltensis, Leach. 



This species is stated b^^ Mr. J. V. Thompson to be common in the 

 harbour of Cove. T'nt. Mag., vol. iii. p. 371. It is pretty commonly brought 

 uj) from deep water in the dredge in the Loughs of Strangford and Bel- 

 fast, but in much smaller quantity than 3Iacropoclia j^ha/anf/ium. Under 

 similar circumstances it has been procured by us at Killery, on the 

 ■western coast. Dr. Ball finds it in Dublin Bay. All the examples of 

 this crab which I have taken were invested with sponge, which generally 

 covers over the body, arms, and legs ; alga^ and zoophytes likewise spring 

 from it. Li this extraneous matter some of the smaller Crustacea find 

 shelter, and, together with the other objects, render the capture of the 

 Inachus Dorseffensis interesting far beyond the acquisition of itself. 



Capt. Beechey, R.N., of H.M.S. Lucifer, brought up a specimen of this 

 Inachns alive in the dredge, from a depth of about 140 fathoms off the 

 Mull of Galloway. See Annals for Sept. 1846, p. 21. 



I. leptochirus, Leach. 



In the 7th vol. of the Annals I noticed an example of this species hav- 

 ing been dredged in Clifden Bay, Connemara, during a natural history 

 tour made to that quarter by Dr. Ball, Prof. Forbes, Mr. Hyndman, and 

 myself ; and that about the same time a specimen was procured by Mr. 

 R. Patterson in Belfast Bay. Subsequently, I have seen specimens from 

 the latter locality in the Ordnance collection. 



/. JDoryncJius, Leach. 



Among a number of Crustacea dredged in Belfast Bay in the summer 

 of 1S38 by my friend Dr. J. L. Drummond, and kindly sent to me, was 

 an example of this species. Specimens from the same locality are in the 

 Ordnance collection. Larne Lough, Mr. Darragh. 



Genus Pisa. 

 P. tetraodon, Leach. 



In the collection of Dr. Ball, now in the Dublin University Museum, 

 are two examples of this species, which were obtained at Roundstone, 

 Connemara, by Mr. M'Calla. 



In August, 1S4.1, I found several of the P. tetraodon thrown ashore at 

 Compton, Isle of AVight. 



Genus Hyas. 

 H. araneus, Leach. 



Mr. Templeton has noticed this species as taken at Carrickfergus ; and 

 native specimens are in Mr. J. V. Thompson's collection. It has been 

 obtained at Youghal and Dublin by Dr. Ball. We take it by cb-edging in 

 the Loughs of Strangford and Belfast, where, too, it is commonly thrown 

 ashore. In the estuary at little more than half a mile from Belfast, a 

 number of large specimens of this crab were captured in the month of 

 October, 1839, on the hooks attached to hand-lines, much to the surprise 

 of the fishermen, Avho had never met with them so near the town before, 

 or in brackish water. The lug-worm {Lnmhrtcus marinus) was the bait at- 

 tacked in this instance by the crabs. Hi/as araneus was taken in the dredge 

 at Bundoran, and dead on the beach of Clew Bay, on the western coast, by 

 our party in July, 1840, and very small living specimens were found under
