MOLLUSCA. 



CLASS CEPHALOPODA. 



Genus Sepia. 

 S. officinalis, Linn., 

 August 23/y/, 1836, — Mr. Brown of Dunclrum 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 Lame." — Ord. Sur. 

 L. Derry. Notices, p. 15, 



'S'. riqiellaria, Fer. 

 Three specimens of the dorsal plate were found at Magilligan by Mr. 

 Hyndman. 



Genus LOLIGO. 

 L. vulgaris, Lam. 

 " Loligo i-ulgaris, 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 I'Jth, 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, thougli 

 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 sj)irits, 

 when they immediately were brought out — though, Avhcn allowed to die 

 out of spirits, the spots never appeared afterwards, though they were in- 

 troduced into spirits. Dublin, Note, Nov., 1839. 



* Forbes and Hanlev considered this to be L. Todarus.
