LAMELLIBRANCHIATA. 335 



Genus Lima. 

 L. Loscombil, Sow. 

 Dredged very sparingly, alive, in the deeper portions of Belfast and 

 Strangford Loughs, on sandy and shelly ground. Single valves of large 

 size obtained in quantity from 23 fathoms, at the entrance to the former, 

 by Mr. Hyndman. Obtained occasionally in the stomach of haddock 

 taken on the North-East coast. In that fish and in gurnard Mr. Humphreys 

 has found it at Cork. 



L. tenera, Turt. 



The Ordnance Museum contains upon a card a fresh-looking specimen 

 of this shell, and one of Lima fragilis labelled with the latter name, as 

 dredged from 7 fathoms in Belfast Bay. L. tenera has long been known 

 to me as found by Dr. Wm. M'Gee in a recent deposit of mud in Belfast 

 Bay, close to the town. 



Near Sana Island, off the Mull of Cantire, Mr. Hyndman dredged single 

 valves of this species in profusion. See Paper in Ann. N. H., vol. x. 



L. suhauricidata, Mont. 



Extremely rare. Two odd valves dredged from about 8 fathoms — sand 

 — in Strangford Lough, in 1837, by Mr. Hpidman and W. T. In the 

 course of a day's dredging in the following year I obtained a single valve 

 in the same Lough. 



Dead shells from Belfast Bay are in the Ordnance Collection. A single 

 valve~di-edged from 23 fathoms — shelly sand — in this bay by Mr. Hynd- 

 man, with quantities of single valves of L. fragilis of large size. 



Division Dimtaeia. 



Family AvicULADiE. 



Genus Avicula. 



A. Atlantica, Lam. 



" It was first observed as a native by Miss Hutchins in Bantry Bay, 

 and announced as British by Mr. Sowerby in his Min. Conch, i. 14." 

 Flem. Brit. Anim., p. 405. 



Dublin Bay, Dr. Turton ; by whom it was found there. 



Avicula hirundo is the name applied to the species in both instances. 

 See Lam., vol. vii. p. 99, 2nd edit. In Mr. Warren's collection I have seen 

 a specimen in 1839, which was found in the latter locality by that gentle- 

 man, and a second one in his possession was stated by the person from 

 whom he obtained it to have been found there. 



who stated that he procured them from Lough Foyle, County Londonderry. 

 This evidence, as Dr. Farran remarks, is not sufficient ; but it seems desirable to 

 notice the circumstance, as the species, which hihabits the western coast of Scot- 

 land, may probably occur on the neighbouring coast of Ireland. I have seen 

 fine specimens from Lough FjTie, Argyleshirc. Pcctcn glaber, Penn. and Mont., 

 believed to be identical with this, has been obtained by Mr. Humphreys at Cork.
