384 Mr. W. Thompson's Additions to the Fauna of Ireland, 



Pleurotoma striolatum, Scacchi, Philippic Enum. Moll. Sicilia?, 



vol. ii. p. 168. pi. 26. fig. 7. 



A single recent, but dead specimen taken with Nassa varicosa, as 

 above. At the late Meeting of the British Association, this was no- 

 ticed as the first instance of the species having been obtained in the 

 British seas ; but Mr. Alder has since informed me that he procured 

 it in Torbay, Devonshire, in the summer of 1845. 



Pleurotoma brachystomum, Philippi, ibid. vol. ii. p. 169. t. 26. 



fig. 10. 



This species was found in Bantry Bay in the summer of 1844 and 

 1845 by Mr. Barlee, who has this season procured it on the west 

 coast of Scotland. It w r as dredged at Zetland by Mr. MacAndrew 

 and Professor E. Forbes, in 1845. 



Pleurotoma laevigatum, Philippi, ibid. vol. i. p. 199 ; vol. ii. p. 169.

Mr. Alder writes to me as follows in Oct. 1846 : — " I have two 

 specimens of what I take to be Pleur. Icevigatum, Phil., from Dr. Far- 

 ran, who got them in Connemara. This shell I have had undetermined 

 in my cabinet for some time, as Mr. Clark gave me worn specimens 

 several years ago, but there was a doubt at that time whether it was 

 not a variety of P. nebula. It appears to be constant in its charac- 

 ters, and a good species." This is the first notice of its occurrence 

 in the British seas. 



Ovula patula, Penn. (sp.). 



A shell of this species, found some years ago on the sandy beach 

 of Magilligan, county of Londonderry, by Mrs. R. A. Hyndman of 

 Dublin, is in the cabinet of Mr. Hyndman at Belfast. 



Natica Montagui, Forb. Malac. Monensis, p. 32. 

 Three or four specimens were obtained from a depth of forty-five 

 fathoms off Cape Clear by Mr. MacAndrew ; — who remarks : " I have 

 besides met with it only on the west coast of Scotland and at Zet- 

 land ; it is there a common shell in from twelve to fifteen and up to 

 fifty fathoms, on a rather hard bottom." A living N. Montagui was 

 dredged in Belfast Bay at the same time with the following species. 



Emarginula crassa, Sowerby, Forbes, Ann. Nat. Hist. vol. xiv. 



p. 410. pi. 11. fig.l. 



A few specimens taken at the Kish Bank in 1845 by fishermen, 

 were found in their boats on their return thence to the Dublin coast 

 by Mr. Doran, jun. (collector of objects of natural history), of whom 

 they were purchased by Mr. Hyndman. This gentleman and Mr. 

 Edm. Getty, when dredging at the entrance of Belfast Bay on the 

 3rd Oct. 1846, obtained from a depth of twenty fathoms five dead 

 shells of this species. These were from 9 to 14 lines in length ; the 

 specimen of this latter size was 10 lines in breadth and 8 in height. 

 A few living and dead specimens of Emarg. Jissura were dredged 

 with the E. crassa on this occasion.
