ON THE FAUNA OF IRELAND. 249 
The larger native Cephalopoda were noticed in the old county histories, 
and a few additional species have been briefly indicated by myself in the 
‘Proceedings of the Zoological Society’ (1834), p. 31, and in the ‘ Annals of 
Nat. Hist, vol. v. p.10. Mr. R. Ball, in bringing before the Royal Irish 
Academy a notice of a new species of Loligo (L. Hblane) on Nov. 30, 1839, 
announced the other indigenous species of that genus*, and on the 10th of 
January, 1842, described before the same Society two new species of Rossia, 
and noticed all the Irish species of Cephalopoda of which he was cognisant. 
These are published in the Proceedings of the Royal Irish Academy of that 
date. An Eledone in my possession, from Belfast bay, though closely allied 
to E. octopodia, seems to be distinct. Octopus vulgaris is given on the au- 
thority of Templeton only, who remarks that it is “not uncommon,’ an €x- 
pression which, taken in connection with the omission of Bled. octopodia from 
his catalogue, leads me to believe that this latter was probably the species 
meant. If the Octopus vulgaris be included, the Irish list contains all the 
British species excepting Eledone Aldrovandi, described by Mr. Macgillivray 
within the present year in his ‘Mollusca of Aberdeenshire.’ Five of the 
Irish Cephalopoda—Sepia rupellaria, Loligo subulata, L. Eblane, Rossia 
Oweni, R. Jacobi—are not known as British species.

No species of this class can be noted with certainty as taken on 
the coast of Great Britain, it being doubtful whether the Peracle 
Flemingi belong to the Pteropoda. This species is only known 
as Irish from some specimens being found by Mr. Hyndman in 
shell-sand collected by Mrs. Hancock at Bundoran, on the coast of 
Donegal, in the summer of 1840. Of Hyalea trispinosa a single 
example with the contained animal was found by Mr. R. Ball on 
the beach near Youghal, county of Cork, some years ago, and at 
the same time with three species of the pedunculated Cirrhipeda, 
(A. levis, A, sulcata, A. fascicularis) a Spirula australis, and an 
Lanthina communis. The Anatife were attached to the mast of a 
vessel, and in their “tangled mass” the Hyaleaand Spirula occurred.

This order was first introduced to the British Fauna at the present meet- 
ing by Professor E. Forbes, who a few years since obtained examples of it in 
the Frith of Forth and British Channel in a species which he has named 
Sagitta Britannica. About the same time, Dr. G. J. Allman obtained similar 
Mollusca (of which he made drawings) on the coast of Cork, but whether 
they be of the same species is uncertain.
