78 OCCURRENCE OF SCYLLARUS ARCTUS IN ENGLAND. 
Note on the Occurrence of the Crustacean Scyllarus Arctus in 
England. By Jonaruan Covon, Esq., F.L.S. 
[Read Dec. 5, 1861.] 
THE Scyllarus Arctus has been of too rare occurrence in Britain 
to have acquired an English name; and, indeed, it appears uncer- 
tain whether hitherto its existence on our shores has ever been 
placed beyond a doubt. It has been said that one example, and 
perhaps two, have been found in Mount’s Bay, in Cornwall ; but 
as the same authority reports it to have its residence in shallow 
water, where it lives in a burrow formed by itself, and we have 
proof that it has been carefully sought for in vain in the district 
referred to, there seems to have been some reason hitherto for 
retaining a distrust of the evidence which could only rest on the 
supposed occurrence of examples twice in the space of a hundred 
years. This difficulty, however, can no longer be felt ; and I have 
the satisfaction of reporting to the Linnean Society the occurrence 
of a specimen, which was obtained at a distance of about a couple 
of leagues from this place (Polperro). The discovery itself is due 
to the diligence of Mr. William Laughrin, A.L.S., whose practice of 
examining the stomachs of fishes has been long continued, and for 
scarce specimens of Crustaceans highly successful ; but it was only 
at the beginning of this present November (1861) that he was so 
fortunate as to find the Crustacean here mentioned. It was in 
the stomach of a Cod, which was taken with a line by a fisherman 
of Polperro, at the depth of about forty fathoms; and from this 
depth of water we learn that this Crustacean is not so entirely, if 
at all, an inhabitant near the shore and in shallow water, as has 
been supposed. This example of a rare Crustacean had suffered 
very slightly from the digestive action of the stomach; and in its 
prison it had for its companions two specimens of Alpheus 
ruber—a species which appears to exist in considerable numbers 
on the ground frequented by the codfish at the depth above 
specified.
