Anomia patelliformis, Linne. 
General, living in 12-90 fathoms. Thompson has it under A.undulata; 
he mentions a fine specimen which was obtained adhering to the inside of a 
quart bottle found in the stomach of a cod-fish ! 
mr. 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 2o fathoms. 
Thompson mentions Carrickfergus oysters which he examined, which weighed, 
before being opened, over 21bs., the animal by itself weighing l^oz. ^ Hynd- 
man states, on the authority of a Groom sport fisherman, that 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. 
Pecten 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 F. 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

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

Pecten septemradiatus, Muller. 
Recorded with doubt {sub F. Fanicus) by Hyndman in his 1857 Report as 
from the Turbot Bank, determined by Dr. Dickie. In 1859 Report he records 
the finding of a second valve, in 80 fathoms, thus confirming Dr. Dickie’s 
determination. 
Pecten tigrinus, Muller. 
Thompson mentions this shell, under the names F. Icevis and F. obsele.us, 
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— R.L1.P. 
Pecten Test®, Bivona. . , 
The following note on this rare species occurs in Hyndman’s 1859 Report 
{sub F. furtivus ):- “Taken alive in 1858 by Mr. Waller and Mr. Hyndman 
on both the Antrim and Down coasts, along with F. striatus. It was taken 
again this year, and at once distinguished by Mr. Jeffreys.”
