The food-fislies i^eceived the first attentiou, such as the cod, 

 haddock, whitiag, ling, eel, flounder, dab, gurnard, herring, 

 and others ; while the lump-sucker, viviparous blenny, catfish, 

 short-spined Gottus, armed bull-head, bimaculated sucker, 

 Montagues sucker, dragonet, rockling, glutinous hag, sand- 

 eel, Gastrosteus spinachia, &c., were also examined. The 

 pelagic ova of the majority of the food-fishes were made the 

 subject of special investigation. The multiple tumours of 

 plaice and the flounder also received notice. Some 

 experiments were further made on phosphorescence and the 

 results embodied in the President's address to the Biological 

 Section of the British Association.* Additional observa- 

 tions on the development of the mussel were carried out this 

 year by Mr. John Wilson. f 



Other published observations included remarks on a new 

 British Staurocephalus , peculiar processes formed by Cerapus 

 on Tubularia, on certain ova, probably of a Cephalopod, 

 according to Mr. Hoyle, from the Forth, and on the milk 

 of the porpoise (chemically examined by Prof . Purdie). 



Prof. Cleland, of Glasgow, lastly, made some anatomical 

 researches on the tail of Myxine."^ 



The capture of a very fine tunny towards the end of the 

 year by a Granton trawler, enabled some observations to be 

 made on a fresh example of this rare fish, about nine feet in 

 length, § and the skeleton will probably form the subject 

 of a subsequent communication. 



The researches on the development and life-histories of 

 the food-fishes were continued by Prof. Mcintosh and Mr. 

 Ed. E. Prince in 1886, in the beginning of which year a 

 noteworthy capture of a huge mass of the large demersal 

 eggs of the catfish {AnarrliicJias lupus) was made in St. 

 Andrews Bay. The embryos were far advanced in these 

 eggs, but a tolerably complete history of this form was 

 drawn up by aid of these specimens, and they were kept in
