[See ‘‘Report on Fauna of Liverpool Bay,” pp. 212 to 221.] 
THE species enumerated in the following list were taken 
by dredging in the following localities :— 
I. In the Turbot Hole, about 17 fathoms deep, close to 
Puffin Island, from the ‘“‘Hyeena,” on 12th June, 1886. 
II. At two points between Liverpool and the Isle of 
Man, 20 and 30 fathoms deep respectively, from the 
‘““Weathercock,” on 28th August, 1886. 
III. At a point between Liverpool and Puffin Island, 
off the west coast of the Constable Bank, from the 
‘““Gamecock,”’ on the 8rd September, 1887. This was the 
British Association dredging excursion. 
The species taken on these occasions are indicated by 
the above numbers affixed to them. 
In addition to these, dredging was carried on occasionally 
in shallow water (3 to 5 fathoms) in Colwyn Bay ; on one 
occasion with considerable success (24th May, 1887), using 
a small dredge having the lips masked with pieces of wood, 
so as to prevent it from digging up the sand, and the net 
lined with canvas. 
Some species were also taken on the shore at low water 
of spring tides at Colwyn Bay. 
Species not previously recorded are marked (*).
