abundant in a dead state. Hyndman notes that it was dredged by his party 
in great quantity in 10 to 12 fathoms at Ballygalley, on the Antrim coast, all 
dead, hut valves united and quite fresh, and that their death was due, m Dr. 
Dickie’s opinion, to deposits from peat-hogs earned down by rivulets. Thrown 
up in abundance at Magilligan strand, hut only single valves. Shells of unusual 
size (2f X 2f inches) may he found at Orlock Point, Co. Down ; they have a 
rather ancient appearance, and are probably washed in from the Turbot Bank. 
Thompson cites this species sub F. pilosus. 
^rca lactea, Xiwwe. 
Hyndman dredged dead specimens of this shell on the Turbot Bank (25-30 
fathoms) on three occasions.

Thompson. Hyndman obtained it dead on the Turbot Bank several times, 
and records a single living specimen which he dredged in 50 fathoms, embedded 
in a pebble of black limestone, off the Copeland Islands. Smgle valves fre-

‘ ‘ * This very perfect and new shell on our coasts was found alive, adhering 
to an oyster from Killinchy in Strangford Lough, by Dr. M‘Gee of Belfast,’ 
Brown. Never found since ’’—Thompson. It is a common Mediterranean 
species, which is not admitted as native by any of our conchologists. There 
must have been some mistake.]

Dredged alive by Waller on the Turbot Bank, and dead m the same vicimty 
by Waller and Hyndman— Hyndman, 1858 Report. 
IVIontacuta substriata, Montagu. 
This little shell, whose peculiar habitat is the ventral spines of Spatangus 
purpureas and other Echinoids, is noted by Thompson and Hyndman as living 
at the entrance of Belfast Lough, in 20 to 30 fathoms, and by Dickie off 
Strangford Lough, in 12 to 15 fathoms.

“Bangor, Belfast Bay (one specimen), 1834, Mr. Hyndman and W.T. 
Bundoran, Mr. Warren ’’—Thompson. Hyndman, and Mr. Wm. Swanston 
dredged it dead on the Turbot Bank. Cushendall-Belf . Mus. Coll. These 
appear to he the only records of a species whose decline as a member of the 
marine fauna must have been rapid, as our pleistocene clays yield it in great 
profusion. 
Kontacuta ferruginosa, Montagu. 
Turbot Bank, dead— Hyndman. The M. ovata mentioned by Thompson is 
probably this species ; he states that several examples of it were found on the 
beach at Bundoran by Mrs. Hancock.
