CIRCULAR CRAB. 155 



for several days in succession, was found to contain them." 

 I have obtained it from the Welch coast ; and I find a 

 very young specimen amongst some rare Crustacea kindly 

 forwarded to me from Scarborough by Mr. Bean. It has 

 been found on the coast of Scotland, in the Frith of Forth, 

 both by Mr. Stephenson of Edinburgh, as stated by Leach, 

 and by my friend Mr. Harry Goodsir, who, however, states 

 that it is rare. I have lately received a specimen which 

 was taken from the stomach of a cod, off the coast of 

 Zetland, by my friends Mr. M' Andrew and Professor 

 Forbes. The accuracy and detail which characterize 

 all the observations of my friend Mr. W. Thompson of 

 Belfast, induce me to quote at length his account of this 

 species as belonging to the Fauna of Ireland. " Mr. Tem- 

 pleton notices a Crab of this species as found by him in the 

 stomach of a codfish, Jan. 17, 1817. In Mr. J. V. 

 Thompson's collection is an Irish specimen, probably from 

 Cork. In January 1839 I obtained a perfect adult male 

 from the stomach of a brill, (Pleuronectes rhombus,) taken 

 at Ardglass, County Down ; it somewhat exceeds in size 

 that figured by Leach, which again is larger than Montagu 

 represents the species. The circumstance of the species 

 being found in the stomachs of the cod and brill would in- 

 dicate its being an inhabitant of deep water. In the 

 Ordnance collection are examples of this Crab from Mo- 

 ville (Co. Donegal), Portrush, near the Giants Causeway, 

 and Carrickfergus. Mr. R. Ball has twice obtained it on 

 the Dublin coast ; on one occasion many specimens were 

 found by him on the beech at Portmarnoch after a great 

 storm."" In confirmation of Montagu's and Leach's obser- 

 vations of the great prevalence of male specimens those 

 observed by the former having been all of that sex, and 

 the latter stating that two females only were found amongst
