very few diatoms occurred, Paralia su'cata once and Navicula spp. in 
the Copepod feces. Here again we have with the small mouth and 
narrow gullet and stomach an absence of Crustacea food in the young 
and only small Copepods in the older forms. 
RHOMBUS MAXIMUS L. Tursor. 
Two specimens were examined fresh from tow-nettings from within 
and outside the Breakwater in August, 11:5 and 14mm. The first 
contained 15 Temora longicornis, the second 2 Balanus naupli and 3 
Centropages typicus. One preserved specimen (mounted) from the 
Young Fish Trawl was too much pigmented for the food to be dis- 
tinguishable. 
RHOMBUS LA‘VIS Ronpet. BrILt. 
Two specimens were examined fresh from the tow-nettings within 
and outside the Breakwater in July and August, 14 and 18 mm. long. 
The first contained Copepod remains indistinguishable, the second con- 
tained 7 Temora longicornis, 3 Centropages typicus, 3 Brachyura zoek, 
9 Hippolyte larvee and a Nematode probably parasitic. Five preserved 
specimens from the Young Fish Trawl, 1914, were also examined, all of 
which contained Podon (cf. intermedius) and one also contained Centro- 
pages. Cunningham (1890) found that young Brill of 2-2 to 2-5 cm. ate 
the young Flounders of 12 mm. and he thinks that they probably naturally 
prey upon young fish at that stage, when they are nearly completely 
metamorphosed. 
Both the young Turbot and Brill have a very large mouth with a thick 
eullet and wide stomach. 
ZEUGOPTERUS PUNCTATUS (B1.). 
Thirty-five specimens examined, preserved, from the Young Fish 
Trawl, 1914, 5 to 10-5mm. long. The smallest contained ova, but at 
6mm. a specimen contained 4 adult Temora longicornis. They appear 
to feed very much like Solea, 23 contained Temora, 10 contained Euterpina 
acutifrons, 2 contained Once (cf. media). Calanus finmarchicus occurred 
in one and Metridia lucens in one. Ova were frequent. A good many of 
the Copepod remains were indistinguishable. 
ZEUGOPTERUS UNIMACULATUS (Risso). 
Fifteen specimens, preserved, were examined from the Young Fish 
Trawl, 1914, 4-5 to 9-5 mm. long. The food content was not easily seen,
