Metridia and occasionally Podon, Acartia, Paracalanus, Oncea and 
Euterpina. Pseudocalanus was also almost the only food of Gadus 
minutus and G. merlangus. The Clupea were all empty and no food was 
found in Pleuronectes microcephalus. Those of the Crystallogobius ex- 
amined (not all as they were almost adult) contained Calanus finmarchi- 
cus, showing that it was present although not taken by the other fish. 
Ca‘lionymus lyra eats almost anything. Besides the above food, many 
of the fish contained ova. 
Haul XIIIa. 
Contained the following fish :— 
45 Pleuronectes limanda. 59 Gadus sp. 
11 Solea variegata. 8 Trigla sp. 
1 S. vulgaris. 1 Labrus bergylta. 
10 Zeugopterus punctatus. 1 Ammodytes sp. 
2 Scophthalmus norvegicus. 34 Callionymus lyra. 
The fish contained the following food :— 
PERIDINIALES. Pseudocalanus elongatus. 
Peridinvum ovatum. Paracalanus parvus. 
Paap: Temora longicornis. 
Centropages typicus. 
Acartia (cf. Clausz). 
Oncea (ef. media). 
INFUSORIA. 
Tintinnopsis ventricosa. 
CLADOCERA, Idya furcata. 
Podon (cf. intermedius). Huterpina acutifrons. 
CoPEPODA. AMPHIPODA. 
Calanus finmarchicus. Apherusa (cf. Clevet). 
Thus the two hauls contain very similar food. Again we find that 
Solea variegata ate chiefly Temora, also Huterpina and occasionally 
Oncea and Acartia but no Pseudocalanus. Solea vulgaris ate Temora 
and Huterpina and Pleuronectes limanda chiefly Temora and Podon but 
not Pseudocalanus. Zeugopterus punctatus ate chiefly Temora but also 
Calanus, Onewa and Euterpina. Again Scophthalmus norvegicus ate 
chiefly Pseudocalanus, although Paracalanus, Euterpina and Temora are 
present. Pseudocalanus is also eaten by the Gadus sp. with several other 
Copepods including occasional Calanus, and by Trigla and Ammodytes. 
Again Callionymus lyra eats a variety, including Apherusa. From these 
notes it will be seen that certain fish do undoubtedly take certain foods 
in preference to others, and this is specially well shown in Solea and 
Pleuronectes limanda, which like Podon and Temora, and almost entirely 
pass over Pseudocalanus although present in abundance.
