Anomia patelliformis, Linne. 



General, living in 12-90 fathoms. Thompson has it under A. undulaia ; 

 he mentions a fine specimen which was obtained adhering to the inside of a 

 quart bottle found in the stomach of a cod-fish ! 



var. striata. Frequent, living in from 12 to 25 fathoms ; Hyndman dredged 

 dead shells in up to 100 fathoms (A. striata.) 



Ostrea edulis, Linne. 



Gregarious, and widely distributed, from low-water mark to 25 fathoms. 

 Thompson mentions Carrickfergus oysters which he examined, which weighed, 

 before being opened, over 2lbs., the animal by itself weighing l^oz. Hynd- 

 man states, on the authority of a Groomsport fisherman, tbat oysters " of large 

 size and good quality " have been brought up on the long Lines from 45 

 fathoms ; this depth is the limit assigned by Jeffreys to the species. 



Fecten pusio, Linne. 



Living in Belfast, Strangford, and Carlingford Loughs, and in the deeper 

 waters of the Channel, in up to 90 fathoms, its other limit of depth being 10 

 fathoms. Thompson notes it sub P. sinuosus. Dead valves frequent on the 

 Derry coast — R.L1.P. 



Pecten varius, Linne. 



10-25 fathoms, attached to old bivalve shells) &c.,like the last species. Of 

 general occurrence around the coasts of Donegal, Derry, Antrim, and Down. 



Pecten opercularis, Linne. 



A common species, and almost universally distributed, living on sand in 

 from 7 to 25 fathoms. 



var. lineata. "Var. lineatus I have dredged in Belfast Bay" — Thompson. 

 I have it also from this locality — B.L1.P. 



Pecten septemradiatus, MiiUer. 



Recorded with doubt {sub P. Danieus) by Hyndman in his 1857 Beport as 

 from the Turbot Bank, determined by Dr. Dickie. In 1859 Beport he records 

 the finding of a second valve, in 80 fathoms, thus confirming Dr. Dickie's 

 determination. 

 Pecten tigrlnus, MiiUer. 



Thompson mentions this shell, under the names P. Icevis and P. obseletus, 

 both of Pennant, as having been found in Belfast and Strangford Loughs. 

 Hyndman dredged it frequently, living in 20-90 fathoms, and Dickie records 

 it from Strangford Lough as Living in 12-20 fathoms. Single valves at Port- 

 rush— Miss Richardson ; and Magilligan— B.L1.P. 



Pecten Testae, Bivona. 



The following note on this rare species occurs in Hyndman's 1859 Report 

 (sub P. furtivus) :— " Taken alive in 1858 by Mr. Waller and Mr. Hyndman 

 on both the Antrim and Down coasts, along with P. striatus. It was taken 

 again this year, and at once distinguished by Mr. Jeffreys."
