DECAPODA. 383 



On examination of this specimen in College of Surgeons' Museum, it 

 seems to be my P. Cuanensis, W. T., March, 1847. 



P. Cuanensis, Thomp. 



Found in Triton erinaceus at Portaferry, and in Bangor Bay, W. T. 



Belfast Bay, Dr. Drummond. 



JioH' 22, 1846. A sp9cimen of this Pagiirns was dredged in Strang- 

 ford Lough, in fifteen to twenty fathoms water, by Mr. Hyndman and 

 myself. It was alive and inhabiting a Trochiis tnaf/us. A conspicuous 

 character was presented in its beautifully ringed antennte. These were 

 of a bright red hue alternating with pure white or yellowish horn-colour, 

 the rings of each colour very unequal in extent. The portion of the body 

 exposed to view, when this Par/urus is in situ, is prettily mottled over 

 with reddish brown and white. 



P. ulidianus, Thomp. 



Portaferry, W. T. 



P. Ilyndmanni, Thomp. 



In Turritella terehra, at Portaferry, W. T. Belfast Bay, Dr. Drum- 

 mond. 



P. laris, Thomp. 

 Portaferry, W. T. 



P. Forbesii, Bell. 

 In 20 to 35 fathoms outside of great Isle of Arran, Professor Melville. 



P. Thompsoni.* 



Genus Porcellana. 

 P. platycheles, Edw. 

 This littoral crab seems to be a local species, but plentiful Avhere it 

 does occur ; Templeton notices it as found on the " "VVhitehouse shore by 

 ]\Ir. James GrimshaAV, jun." On the beach near Carrickfergus, a few 

 miles distant from that locality, it was procured in abundance in June, 

 1835, by the late Mrs. Patterson of Belfast, who subsequently obtained it 

 near Cultra, on the County Down shore of the Bay. Dr. Ball states that 

 this species is very abundant on the shores of the County Dublin, and 

 especially at Portmarnock ; he remarks that in once turning over a large 

 stone here in cold wintry Aveather the under side was entirely covered 



* P. Thompsoiii, Bell. 



Dredged in 50 fathoms, entrance to Belfast Bay, Mr. Hyndman. This 

 fine species is described in the end of Bell's Crustacea with the following re- 

 marks : 



" I have a melancholy gratification in dedicating this species by name to a 

 gentleman who for many years was justly considered as the representative of the 

 Zoology of Ireland, and whose acute discrimination and persevering enthu- 

 siasm in his fovourite pursuit were only equalled by the liberal and unselfish 

 feeling with which he placed his treasures in the hands of his fellow-labourers, 

 whenever he believed the interests of science would be thereby furthered. The 

 specimen from which the above description is taken was placed in my hands 

 by my lamented friend, only a very few days before his xuitimely death de- 

 prived the science of Ireland of one of its most distinguished ornaments, and 

 society of as kind and true-hearted a man as ever lived." — {Bell's Crustacea, p.
