four zones into which the ocean bed has been divided, he described 
a method he had found of service in carrying on conchological 
work when the sea is too rough to permit of dredging. The plan 
was to row out some yards and cast anchor—the anchor most 
suitable being a five-hooked grapnel. He then paid out sufficient 
rope to let the anchor scratch along the bottom as the boat drifted 
with the wind, sometimes -rowing backwards, anchor down, to 
obtain a good grip; then up anchor, with the mass of tangle 
attached, which was carefully lifted into the boat. This opera- 
tion was repeated till the boat was laden. Thecargo, having been 
carried ashore, often yielded good results. Mr. Knight exhibited 
a number of specimens of what had been obtained in the manner 
described, including— : 
Terebratula caput-serpentis (L.)—Loch Fyne. 
Anomia ephippium, L., var. cylindrica, Gm.—Loch Fyne, 27 fms. 
Pecten pusio (L.)—Loch Leven. 
» varius (L.), var, nivea, Macg.—Oban Bay. 
5  septemradiatus, Miill.—Firth of Clyde. 
»  tgrinus, Miill.—Loch Fyne.
