with TLemora longicornis and Podon (probably imtermedius). Temora, 
as many as 6 in one individual, occurs in 51 out of 221 specimens, in all 
hauls except XVII and XXII (only one Solea variegata in the latter). 
They also are contained in the smallest (4 mm.) and the largest (11-5 mm.). 
A specimen of 4mm. can swallow a Temora 15mm. long. Other Har- 
pacticids occurring rarely are Longipedia Scotti and Microsetella norvegica. 
Oncea (ct. media) occurs fairly frequently, as many as 4 together, male 
and female, female the commonest. Onccwa media is a species not hitherto

O. mediterranea and O. venusta and the caudal furea are different. It 
occurs in 25 out of 221. Coryceus anglicus occurs rarely, Acartia (ef. 
Claus) and Pseudocalanus elongatus occur once only, singly, and evi- 
dently not liked by the fish, as they certainly occur in the hauls and are 
taken by other young fish (e.g. Scophthalmus). 
Podon intermedius occurs in 76, thus it is the form most frequently 
taken. It occurs in specimens from most of the hauls, in the smallest 
and also in the largest. 
Balanus cypris stages occur in 9 specimens. Larval gastropods occur 
only occasionally. Besides the ova, minute organisms such as Infusoria,
