On the Larval and Post-Larval Fishes obtained 

 in Loch Fyne. 



A detailed list of the young fishes which were taken in the tow-nets 

 with the pelagic ova and other forms is given below. The identification 

 of the specimens was not rendered easier by the fact that they were 

 preserved along with the Copepoda, etc. I had not the opportunity of 

 separating them at the time from the rest of the tow-net collection, and 

 in many cases it was almost impossible to identify even the genus of the 

 fish. Preservation in formalin was found to answer very well, so far as 

 the retention of black pigment is concerned ; other pigments disappeared. 



The labour of identification was very materially lightened for me by 

 the kind assistance rendered by Professor M'Intosh, who, in addition to 

 naming a number of the specimens, also placed his collection of young 

 fishes at my disposal for the purpose of comparison. In a number of 

 cases the genus to which the form belongs is alone given. 



The species represented are the following : — Cod (Gadus callarias), 

 Coitus bubalis, Cottus (sp.), Cyclopterus lumpus, Dab (Pleuronectes 

 limanda), Flounder (PI. flesus), Gobius minutus, Gobius (II.), Gunnel 

 (Centronotus gunnellus), Lepadogaster bimaeulatus, Liparis montagui, 

 Long Rough Dab (Drepanopsetta platessoides), Mackerel (Scomber 

 scombrus)^ Onos (sp.) (Motella), Pipe-fish (Syngnathus, sp.), Plaice (PI. 

 platessa), Saithe (Gadus virens). 



Species B. — The forms included under this designation are mainly 

 mackerel, but since, in the case of the very small examples, some 

 confusion may arise between that fish and the species of Cottus and 

 Trachinus, they have been placed under a general term.
