Strangford or Belfast, it has been procured in the adjacent Lough of 
Larne. 
Ardmore, Mrs. Mackesy. Bundoran, Mrs. Hancock. 
S. clathr atula, Turt. 
As, in the table accompanying my report, this species appears to be as 
widely distributed as the last, it must be stated that it is generally a much 
scarcer species. 
Ardmore, Mrs. Mackesy. Bundoran, Mrs. Hancock. 
S. Turtoni, Turt. 
Turton named this Scalaria after his daughter. He remarked, when 
describing it, “ In many parts of Ireland, but especially about Balbriggan, 
they are found crawling among the rocks.” Conch. Diet. p. 208. This 
locality is on the Dublin coast, where the species has also been obtained 
by Dr. R. Ball and Mr. Warren. It has been procured in a recent de- 
posit of mud in Belfast Bay. At Newcastle, County Down, this recent 
shell has been met with by Dr. Drummond. 
Specimens from Dundalk Bay are in Mr. Hyndman’s collection. At 
Youghal it has been rarely found by Miss M. Ball. 
S. Trevelyana (W. T. in Ann. N. H., vol. v. p. 245). 
Specimens of this shell were kindly presented to me in 1835 by Mr. 
John D. Humphreys of Cork, as found on the coast of the County of that 
name. Mr. Hyndman possesses a specimen from Magilligan. When I 
noticed this species in the Annals, it had been merely named and not de- 
scribed by Dr. Leach from specimens found on the coast of Northumber- 
land. 
Family Cerithiad^e. 
Genus Cerithium. 
C. Pennantii, mihi. 
Of this shell there is a specimen from Youghal in Miss M. Ball’s col- 
lection, agreeing with the descriptions of Fleming and Brown, but only 
tolerably represented in Pennant’s British Zoology as Turbo tuberculata, 
and in Brown’s Illustrations as C. fuscatum. Professor E. Forbes haying 
informed me that the Turbo tuberculata of Linn, is a different shell, and 
that the Cerithium to which Costa applied the name of C. fuscatum is 
likewise distinct, I have considered it necessary to bestow a new name on 
the present species (Ann. N. H., vol. v. p. 12, 1840). 
C. tuberculare (W. T., Ann. N. H., vol. v. p. 12). 
First noticed as from M. Malbay, common, from being included in 
Professor Harvey’s MS. Catalogue. 
Dredged in Clifden Bay, West coast, between 4 — 10 fathoms (bottom 
Nullipora and sand), in July, 1840, by our party. From similar ground 
in Bantry Bay I have obtained it. Sandy beach at Magilligan ; and in 
stomach of Scaup duck shot in Belfast Bay. — W. T. 
Ardmore, Mrs. Mackesy. 
C. reticulatum, Brown. 
Common in shell-sand on the beach of Belfast Bay, and dredged alive 
and very fine from various depths, also sub-fossil ; a considerable consti- 
tuent in the formation of the Kinegar, Holywood. In quantity in the
