Part III — Tenth Annual Report 
in 3; Crangon in 3 ; Arcturus in 2 • Mysis and Atylus, each in 1 ; uniden- 
tified amphipods in 9 ; unidentified crabs in 4 * unidentified Crustacea 
in 9 ; larval Crustacea in 1. 
Molluscs were found in 115 stomachs (19 per cent.). The forms found 
were Pecten sp. opercularia and 1 in 33 ; Solen in 24 ; Scrobicularia, sp. 
niUda and ? in 21; Mytihis in 4; Buccinum in 3; Modiolaria and 
Cardium, each in 2 ; Philine scabra, Venus, Montacuta bidentata, Corbula 
gibba and Rossia, each in 1 ; unidentified gastropods in 3 ; unidentified 
lamellibranchs in 2 ; unidentified nudibranchs in 1 ; unidentified 
molluscs in 15. 
Fish were found in 30 stomachs (5 per cent.). The forms found were 
sand-eels in 5 ; herrings in 3 ; unidentified fish in 22. 
Ascidians (Pelonaia and T) were found in 3 ; Coelenterates were found 
in 6 stomachs : consisting of Eudendrium and Beroe, each in 1 ; anemones 
in 2 ; zoophytes in 1 ; and medusidse in 1. 
The chief food of common dabs in the Firth of Forth is evidently 
hermit-crabs ; no other form of food is so constantly found. Other 
Crustacea are unimportant. Next to hermit-crabs, but to a much less 
extent, come annelids. After these come sand-stars, clams, Scrobicularia 
and Solen. No other organism of the whole series found, with the excep- 
tion of fish, can be looked upon as forming anything more than a rare 
article of diet. 
Long Eough Dabs. 
In all 1512 were examined on the Firth of Forth. Of these 925 were 
empty, and 569 contained food that could be identified. 
Echinoderms were found in 167 stomachs (29 per cent.). The forms 
were Ophioglypha sp. texturata and 1 in 43; Ophiocoma in 20; Ophiura sp. 
albida in 18; Ampliiura in 8; Ophiothrix in 7; Asterias in 7 ; Amphiura 
sp. filiformis in 4 ; Opliiopliolis in 3 ; unidentified sand-stars in 57. 
Annelids were found in 52 stomachs (9 per cent.). The forms were 
Sipunctdus in 3 ; Sabella in 2 ; Echiurus, Pectenaria, and Sagitta, each 
in 1 ; unidentified annelids in 44. 
Arthropods were found in 282 stomachs (49 per cent.). The forms 
were Crangon in 126 ; Portunus in 30 ; Eupagurus in 23 ; Pandalus in 
21 ; Mysis in 13 ; Erythrops in 9 ; Nephrops and Ampelisca each in 3 ; 
Hyas, Diastylus, Galathea, and Cuma, each in 1 ; hermit-crabs in 21 ; 
unidentified schizopods and amphipods, each in 7 ; unidentified crabs in 6; 
unidentified Crustacea in 9. 
Molluscs were found in 38 stomachs (6 per cent.). The forms were 
Scrobicularia in 14 ; Solen in 13; Pleurotoma in. 2 ; Cardium in 2; 
Buccinum, Turritella, Natica, Mactra, and Rossia, each in 1 ; unidentified 
lamellibranchs in 2. 
Fish were found in 84 stomachs (14 per cent.), The forms were gobies 
in 17 ; whitings in 5 ; long rough dabs in 4 ; sand-eels, pogge, lemon 
soles, and gurnards each in 2 ; Motella, dragonet and herrings, each in 
1 ; unidentified fish in 47. 
It appears that in the Firth of Forth Crangon forms by far the most 
mportant article of food for long rough dabs. Sand-stars, hermit-crabs 
and fish follow a good way behind these ; and other forms are relatively 
unimportant when compared with these. 
Witch Soles. 
In all 217 were examined. Of these 55 were empty, and 150 contained 
food that could be identified.
