Gurnards. 

 (Trigla gurnardus). 



Of 156 stomachs examined, 42 were empty, and the contents of 10 

 were indistinguishable : 104 contained matter that could be identified. 



Echinoderms were not found in any of the stomachs. 



Annelids were found in only 2, and consisted of Priapulus at 

 Station I., in one in August, and of an unidentified annelid at Station V., 

 in one in June. 



Arthropods were found in 89 stomachs (85%). They consisted of 



(1) Crangon (sp. allmanni and vulgaris in nearly equal proportions). 

 The proportion of the stomachs containing Crangon to those containing 

 distinguishable matter at the various Stations is as follows : — Station I., 

 none of 7 ; II., 2 of 9 ; III., 2 of 10 ; IV., 0 of 6 ; V., 1 of 4 ; VI., 4 of 

 34 ; VII., 0 of 8 ; VIII., 8 of 16 ; IX., 7 of 10. The proportion during 

 the various months at all the Stations is — June, 4 of 39 ; August, 2 of 23 ; 

 September, 5 of 22 j October, 3 of 9 ; November, 10 of 11. At Stations 



VIII. and IX., Crangon formed the greatest food supply of gurnards in 

 September (no fish were examined in October) and in November : in 

 the latter month 10 of 11 stomachs examined containing these forms : 



(2) Nephrons (sp. norvegicus) at Station III., in one in June ; at Station 



IX. , in one in September ; and at Station IX., in one in November : 



(3) Portunus (sp. depurator, pusillus, and corrugattis), at Station I., in 

 one in August; at Station II., in two in September; at Station III., in 

 one in June, in two in August, and one in October ; at Station IV., in 

 six in August ; at Station VI., in one in June and one in August ; at 

 Station VII., in two in August and in four in September. Portunus 

 was thus most abundantly found in August, viz., in 52% of stomachs 

 examined, the percentages for June, September, and October being 29, 

 27, and 11 respectively : (3) Pandalus (sp. brevirostris), at Station V., 

 in one in June and one in August ; and at Station VI., in twenty-two in 

 June and in one in September : (4) Porcellana (sp. longicornis), at 

 Station [., in one in October : (4) unidentified crabs, at Station I., in two 

 in October ; at Station III., in one in August ; at Station VIII. (hermit 

 crabs), in one in August and in one in September: (5) unidentified 

 amphipods, at Station I., in two in September ; at Station VI., in two in 

 June ; at Station VIII., in one in June \ and at Station IX., in one in 

 September : (6) unidentified schizopods. With the exception of one at 

 Station VI. in September, all the fish, six in number, containing these 

 were found in August at Stations I., III., VI., and VII. 



Molluscs were found in 3 stomachs (2%). They consisted of (1) 

 unidentified lamellibranchs, at Station VI., in one in October : (2) Eolis, 

 at Station VI., in one in June : (3) cuttle-fish (1 Eossia), at Station 

 VIII., in one in August. 



Fish were found in 20 stomachs (19%). They consisted of whiting, 

 sand-eels, herrings, and lump-suckers. 



Cod. 



(Gadus morrhua). 



Of 251 stomachs examined, 37 were empty, and the contents of 3 were 

 indistinguishab'e : 211 contained matter that could be identified. 



Echinoderms. — The only specimens of Echinoderms found were an 

 Ophiothrix at Station I., in September, and an Ophiocoma (sp. bellis) at 

 the same Station in December.
