PLEURONECTES LIMANDA L. Das. 
1353 specimens of the ‘“ Dab” were examined, preserved, from the 
Young Fish Trawl, 1914. These measured from 4 to 17 mm. in length. 
416 contained no food, chiefly the smaller specimens ; in those from 4 to 
4-5mm. no food could be detected, the food taken at this stage probably 
being very minute. Remains of small Copepods first occurred in those 
of 5mm. Fairly large Copepods, such as Temora, occurred from 7 mm. 
upwards, but not in those of a smaller size. Nearly all the food recognized 
was Crustacea or ova. 
Of the Crustacea recognizable Podon (cf. intermedius) was the 
commonest, occurring in 427. Those from Hauls V to X and XVII 
to XLVIII did not contain Podon, which looks as if Podon if 
present in numbers is preferred, but certain Copepods may be taken 
instead. 
Copepods, Copepod nauplii, Copepod remains and feces occurred in 
382, Crustacea remains, indistinguishable, in 91. Temora longicornis is 
the commonest Copepod, occurring in 170 from 7mm. long upwards. 
Other Copepods were Harpacticids in 52,46 of which were Huterpina 
acutifrons, the others being unrecognizable. Other Copepods occurring 
rarely are Pseudocalanus (in 10), Oncea (in 7), Metridia lucens (in 3) 
Coryceus anglicus (in 3). The only other Crustacea recognizable were 
the Cypris stages of Balanus in one specimen. 
Ova occurred in 198 specimens, spores (2?) in 10, larval Mollusks 
in 2. Diatoms, Peridinians, Infusoria and Distephanus speculum 
occurred occasionally. Diatoms in 13, 6 of which were Parala 
sulcata, 1 Pleurosigma sp., 1 Fraqillaria sp., 1 Coscinodiscus sp. The 
only Infusoria were Tintinnopsis ventricosa in 6. Two Distephanus 
speculum occurred in one of 6 mm. Kyle (1898) examined 30 out of 
300 young Dabs measuring 10 to 16 mm., and found they only con- 
tained diatoms (Coscinodiscus and others) although Copepods were 
resent in the water. The present records certainly show that 
Crustace are taken earlier. 
PLEURONECTES FLESUS L. FLounper. 
Two fresh post-larval Flounders were examined from the tow-nettings, 
one from inside and one from outside the Breakwater in May. The 
first, 8-5 mm. contained nothing, the second, 10-5 mm. which occurred 
on May 31st, when the tow-nettings were full of the flagellate Phaocystis, 
had its alimentary canal full of Phwocystis spores. Forty-two preserved 
specimens from the Young Fish Trawl, 1914, were examined, 5:5 to 
10-5 mm., 15 of which contained nothing, the rest diffuse remains almost
