in 20, Temora longicornis in 6 only, and Temora nauplii in 4. Calanus fin- 
marchicus (juv.) in 2 and Coryceus anglicus in one. 
It is thus seen that a variety of Copepods is taken, but Pseudocalanus 
markedly predominates. 
Seventy-one specimens were in Haul X and these contain almost 
entirely Copepods, chiefly Pseudocalanus and Metridia, Acartia also being 
fairly frequent. Huterpina and Oncaea not common and Podon occurs a 
few times, Temora only once. Comparing this with Solea variegata from 
the same haul we find Solea has chiefly eaten Temora and Podon, so that 
selection of food must take place. It is the same in Hauls XI, XII and 
XIII. In XII Pleuronectes limanda has also selected chiefly Podon 
and a few Temora. In Haul XVII large Copepods seem rare and in 
XXIII the fish have eaten little. 
GADID. 
The Whiting, Gadus merlangus, is the commonest gadoid in the tow- 
nettings, the Pouting, G. luscus, coming next. From the Young Fish 
Trawl a number of G. merlangus and G. minutus were examined, the 
Whiting not showing the food well in the preserved material. Pseudo- 
calanus appears to be the favourite food of all the post-larval gadoids 
except the very young specimens. 
GADUS MORRHUA L. Cop. 
Only one specimen from inside the Breakwater, fresh from the tow- 
nettings in May, 19mm. This contained one Calanus finmarchicus and 
one Temora longicornis. 
GADUS MERLANGUS L. Wuitinc. 
Twenty-seven specimens examined fresh from the tow-nettings, April 
to July, from both inside and outside the Breakwater, from 4 to 34 mm. 
The first obtained on April 2nd and 4th were 4mm. long; one had 
nothing inside, the other had 2 nauplii of Calanus finmarchicus and one 
Coscinodiscus Granii ; one of 2-5 mm. ca. contained no food, but one of 
3mm. contained Copepod remains. The rest, excepting 3 which were 
empty, contained Copepod remains, of which 11 contained Pseudocalanus 
elongatus (from 1 to 3), 2 contained Paracalanus parvus and the rest were 
indistinguishable.. The specimen of 34mm. contained indistinguishable 
Copepods. 
At 4mm. nauplii are eaten and at 5 mm. full-sized Pseudocalanus. 
171 preserved specimens from the Young Fish Trawl, 1914, were also
