35 



Portunus arcuatus, Leach. 



Very rare in stomachs examined in January. 

 Atelecyclus septemdentatus i Mont. 



This species occurred sparingly on one or two occasions. 

 Corystes cassivelaunus, Pennant. 



This also occurred sparingly, but on one occasion a dozen small 

 specimens in a stomach in January. 

 Lithodes maia, Linne. 



Three small, fairly perfect specimens were obtained in a stomach 

 examined in October, and a larger female carrying eggs, but 

 with the shell soft and somewhat damaged, in one examined 

 in February. 

 Geryon tridens, Kroyer. 



A fairly large specimen of Geryon was found in one of the 

 stomachs examined in October, and two smaller specimens 

 in those examined in December. 

 Eupagurus bernhardus, Linne. 



Tolerably frequent, especially in the winter months. 

 Eupagurus prideaux, Leach. 



Obtained sparingly on two or three occasions. 

 Eupagurus cuanensis, Thomps. 



Rare in one or two stomachs in December. 

 Eupagurus pubespens, Kroyer. 



Fragments apparently belonging to this species occurred sparingly 

 on one or two occasions in December. 



Galathea sp. 



Rarely met with, and only young or imperfect specimens. 

 Munida bamffica, Pennant. 



Munida was not infrequent during the winter months. In one 

 of the stomachs examined in October, 21 specimens, large 

 and small — mostly small — were obtained, and 6 in another. 

 Nephrops norvegicus, Linne. 



This crustacean was moderately common, especially during the 

 winter months, not a few of the specimens being apparently 

 adult ; some of them measured 8 to full 9 inches to the end 

 of the claws. 

 Crangon allmanni, Kinahan. 



Rare, and probably derived from the stomachs of fish swallowed 

 by the halibut. 

 Pandulus montagui, Leach. 



Rare ; observed only on one or two occasions. 

 Thysanoessa neglecia, Kroyer. 

 Euthemisto compressa, Goes. 



Both of the species named were doubtless derived from the 

 stomachs of sand-eels and herrings swallowed by the halibuts. 

 Girolana borealis^ Lilljeborg. 



Several specimens were met with in one of the stomachs 

 examined in October, probably having been swallowed with 

 the Gadoids to which they were adhering as parasites. 

 Lemma branchialis^ Linne. 



Fragments were observed on one or two occasions, having 

 doubtless been fixed on the gills of Gadoids swallowed by 

 the halibut. 



Mollusca. 



Fusus antiquus, Linne\ 



Two stomachs contained each an operculum only; another con- 

 tained the head (with operculum attached) of a tolerably 

 large specimen.
