CRYSTALLOGOBIUS NILSSONI v. Dus. & Kor. 
One fresh specimen from tow-nettings outside the Breakwater, October, 
measuring 21mm. contained nothing. Twenty-eight preserved speci- 
mens from Haul XIII Y.F.T. 1914, all contained Crustacea, 13 contained 
Podon, and 2 Calanus finmarchicus, many remains probably representing 
the latter species. The specimens measured from 26 to 37 mm. 
CALLIONYMUS LYRA L. Draconer. 
Forty-six fresh specimens from the tow-nettings were examined, from 
both inside and outside the Breakwater from March to October, from 
15 to 8mm. Up to 2mm. yolk was present but diatoms or green food 
was sometimes present. Coscinodiscus excentricus and C.sp. Paralia 
sulcata, Navicula sp. and Pleurosigma sp. were present, at 3mm. Huter- 
pina was eaten. Balanus nauplii occasionally. Many of these small ones 
were empty. 
222 preserved specimens from the Young Fish Trawl] 1914 were 
examined, from 3to 13mm. At 3-5 mm. Pseudocalanus is eaten. After 
that a variety of Copepods including Onceea, Euterpina, Coryceus, Temora, 
Idya, Paracalanus, Calanus and Centropages, with occasional Podon and 
Apherusa, also ova. The commonest Copepods taken are Pseudocalanus 
and EButerpina, Temora coming next. Callionymus lyra is thus a very 
miscellaneous feeder, beginning with diatoms when very young and soon 
feeding almost exclusively on Copepods. 
CYCLOGASTER MONTAGUI Donov. 
Four specimens from both inside and outside the Breakwater, March 
and April, 3-5 to 4.5mm. Two contained nothing ; one, diffuse brownish 
food remains, and one, remains of Crustacea. 
CYCLOPTERUS LUMPUS L. Lump Sucker. 
Two specimens from amongst the Zostera outside the Breakwater in 
July and August, 15 and 18mm. That of 15mm. contained 5 Amphi- 
poda indet., and 1 Harpacticus uniremis, the other contaimed remains of 
Eupagurus \arve and other larval decapods. 
- LEPADOGASTER CANDOLLEI. Risso. 
Nine specimens from both within and outside the Breakwater, July 
and August,4to8mm. One of 4mm. contained two young Temora, all 
the others (except one with nothing in it) contained remains of Copepods, 
including Temora nauplii and Harpacticids.
