IOLLUSCA, 
CLASS CEPHALOPODA. 
Genus Sepia. 
S. officinalis, Linn., 
August 23rd, 1836, — Mr. Brown of Dundrum states, is occasionally 
taken here, and called cat-fish — the “ bone ” is called may-shell, and is 
much valued by the country people, as of old, for its medicinal uses. 
A mutilated specimen was found at Queen’s Bridge, Belfast, in July, 
1850. 
“ Bones of this species have been washed ashore at Larne.” — Ord. Sur. 
L. Derry. Notices, p. 15. 
S. rupellaria, Fer. 
Three specimens of the dorsal plate were found at Magilligan by Mr. 
Hyndman. 
Genus Loligo. 
L. vulgaris, Lam. 
“ Loligo vulgaris, Calamary ; Ordnance Survey of Londonderry : — 
Great Cuttle of Pennant, taken in the Culmore net.” P. 16. 
Common at Dublin, Dr. Ball. A full-sized one, as accurately described 
to me, was found at Newcastle (Oct. 19th, 1851), and the only one an 
acute fisherman living here ever saw. 
Loligo vulgaris. Dec. 20th, 1848. 
A full-grown specimen found on the beach, Dundrum (County Down), 
was received at the Museum — perhaps thrown ashore by the hurricane of 
the 15th ; it was alive on the 19th, when brought to Dundrum. 
L. sagittata, Lam.* Glendore, Aug., 1838. 
About one hundred were seen by Prof. Allman in Glendore Bay, the only 
time he ever met with them. He describes their change of colour as very 
beautiful, until they threw out the ink and obscured themselves, though 
they did not entirely so conceal themselves in the sea. About a dozen put 
into a pail of sea-water, containing 5 or 6 gallons, threw out as much ink 
as to conceal themselves. The spots which, now confluent, give a purple 
colour to the body were invisible before Mr. A. put them alive into spirits, 
when they immediately were brought out — though, when allowed to die 
out of spirits, the spots never appeared afterwards, though they were in- 
troduced into spirits. Dublin, Note, Nov., 1839. 
Forbes and Hanley considered this to be L. Todarus ,
