180 DXITBLIN NATURAL HISTOaT SOCIEir. 



Portunm puher. — Bangor. 



Portunm carrugatus. — Bangor and Ballyholme Bays. 



Portunus arcuatm. — Bangor. 



Portufius d^purator. — Ballyholme, Whitehead. 



Portunus pusillm. — Groomsport and Whitehead. 



Portunus holsatm. — A single specimen off Wliitehead. 



Bernhardus strehlonyx. — Common everj^where. 



*Benihardus Prideauxii. — I did not meet this species. Mr. J. C. Hynd- 

 man showed me several typical specimens of it ; in my Dublin lists 

 the range given is incoiTect ; one specimen only occurred to me 

 there, and that imperfect. 



Bernhardus Cuanensis. — Ballyholme and Whitehead. 



Bernlmrdus Ulidianus. — This is the species which, on my discovery of 

 it in Dublin Bay, I called Eblanensis; the examination ofW. Thomp- 

 son's original specimen enables me to correct this error. It is eX" 

 trcmely common everywhere. 



Bernlmrdus Hyndmanni. — Ballyholme, Bangor, Whitehead, and the 

 Gobbins. 



^Bernhardus IcBvis. — ^ot uncommon. Off Whitehead and Bangor. 



Bernhardus Thompsoni. — Whitehead, Bangor, and the Gobbins ; com- 

 moner than in Dublin. 



Galathea Andrewsii Extremely common ; this is also very common 



on the south-west coast, where Dr. E. Perceval Wright and Professor 

 J. Reay Greene inform me it occurs as a littoral species. Professor 

 Thomas Bell showed me specimens of the same species from deep 

 water off Madeira ; and M. Lucas, Paris, showed me a bottleful of 

 specimens of the same species, captured off the coast of Algiers. 



Munida Rondeletii. — Occurs not uncommonly in deep water, as Mr. Gi 

 C. Hyndman informs me. 



Crangon vulgaris. — Appears as common here as in Dublin. 



Crangon fasciatus. — One specimen, very beautifully coloured, occurred 

 near the shore in Ballyholme Bay ; several specimens occurred in a 

 black sand off the Gobbins ; these latter were in spawn. This spe- 

 cies does not occur in the published Belfast list. In the Belfast 

 Museum, however, there are several specimens included under C. 

 vulgaris J and bearing the following localities in William Thompson's 

 hand:— "Portaferry, July, 1838, W. T. ; Belfast Bay, 1839, E. 

 Getty ; and Donaghadee, Dr. Drummond." 



* Crangon spinosus. — Two specimens, same locality as last; does not oc- 



cur in Belfast list. 



* Crangon Pattersonii (n. «.). — Two specimens at the Gobbins. This spe- 



cies differs from last in the smoothness of the first to fourth rings of 

 the abdomen ; the fifth ring has a triangular central elevation at its 

 inferior border ; the sixth is plane above ; the telson sulcate ; the ros- 

 trum rounded and slightly concave above. I hope to describe it more 

 fully shortly. 



The specimens taken were in spawn. I can find no species, 

 either recorded or in the collections in London or Paris, which agi-ees
