of Ci/there (?) ppllucida Averc occasionally noticed, as \Vell as a few 

 Foraminifera and fragments of Crangon vulgaris. A further sample of 

 seven fishes, which measured from 10 to 15 centimetres, had Annelids in 

 the stomachs of five of them ; Amphidottcs sp. was observed in one, but 

 the contents of the others could not be distinguished. Eighteen 

 specimens, also from Annan, and collected on July 30th, 1900, had very 

 little in their stomachs, the only organisms identiiied being sn)all 

 lamellibranchs {Cardium sp.), Gasteropods (liissoa sp.), Canuella 

 perplexa, the remains of one or two Amphipoda and small Annelids. 



In the stomach of a moderate-sized Plaice obtained from the fishermen 

 at the Bay of Nigg on March 29th, 1900, the following species were 

 obtained: — AmatliiUa homari, Gamwarus locusta, Idothea baltica and 

 Idothea emarginata; while in the stomachs of a few Plaice, also of moderate 

 size, taken in the Bay of Nigg on April 11th, 1901, only the remains of 

 Annelids were observed. 



The names of the o]'ganisms from the stomachs of the Plaice referred to 

 in the preceding notes will be found in the annexed Table : — 



Species Found in the Stomachs op Plaice. 



Lemon Sole. Pleuronedes microcephcdus, Donovan. 



Several Lemon Soles were examined, but the remains of Annelids 

 formed, as usual, nearly the whole of their food ; the only other thing 

 worth recording here i? an example of Acidicola rosea, Thorell, found in 

 the stomach of a specimen from the Moray Firth ; this Copepod lives 

 within the branchial sac of an Ascidian, and probably the Lemon Sole 

 had swallowed one of these Ascidians, and the Acidicola had then some- 

 how parted company with its host. 



It has been pointed out in former reports on the food of Lemon Soles* 

 that Annelids constitute by far the largest proportion of it, but it has 

 also been shown that a considerable number of the stomachs that have 

 been examined have been empty. With reference to the frequent appar-

 Itepori.t of (he Fishfiii Board for Scotland. I will refer later ami more particularly to 

 some of the results given in these papers, but the following figures may bo noted here. 

 Out of 821 stomachs of Lemon Soles examined, 333 were empty or contained matter that 

 was not distinguishable and 383 contained Annelids, so that only 105 (or scarcely 11^ 

 per e3iit.) of those stomachs contained other than Annelid food.
