96 PISCES. 



Gadus vikens? linn^us. 



{Coal Fish.) 



Plate X., Fjgs. 13, 14. 



This is another of the Gadoid species, the otoliths of which 

 were recognised in the Corallirie Crag by Mr. Higgins and noticed 

 by Prof. Prestwich (loc. cit.), but I have not been able satisfactorily 

 to identify the species as a Crag fossil, although a small otolith 

 from the Coralline Crag of Sutton, in the possession of Mr. Kendal, 

 and two still smaller from the same place, in the Museum of 

 Practical Geology, agree so nearly with some young examples of 

 this species that provisionally I place them here. 



Gadus vireiis is now living on the northern Atlantic coasts of 

 North America, reaching as far as Spitzbergen, and on the Western 

 European coasts as far soutli as the Mediterranean. 



GA.DUS POLLACHIUS, LINN^US. 



(Pollack.) 



Plate X., Figs. 15a, b. 



This is the sixth species of Gadoid the otoliths of which were 

 noticed by Mr. Higgins and Prof. Prestwich (loc. cit.) in the 

 Coralline Crag; but I have not yet been able to recognise it from 

 that horizon, although Mr. J. Heeve has a large otolith, not quite 

 perfect, from the Upper Bed of the Norwich Crag at Bramerton, 

 agreeing so closely with the recent forms tliat 1 have referred it 

 to this species. An otolith ol a similar character from the Weybourn 

 Crag at East Eunton has been already placed on record (Mem. 

 Geo]. Surv., Vert. Forest Bed, p. 128, Plate xviii., fig. 24, 1882). 



The Pollack is now living on the European shores of the 

 Atlantic, and is rare in the Mediterranean. 



Gadus elegans, koken. 

 Plate X., Fig. 16. 



A number of small otoliths in the Museum of Practical Geology, 

 some from the Coralline Crag of Sutton, and others said to be 

 from the Red Crag, have a close resemblance to those which have 

 been referred to Gadus pseudcBglefinu.i, but are proportionately 

 broader, and in this particular they differ also from the otoliths 

 of yoving Haddocks {G. oeglefinus). They agree, however, more 

 closely with the otolith fi-om the Oligocene which Herr E. Koken 

 (Zeitsch. deutsch. geol. Ges., Vol. XXXVI., p. 544, 1884) has 

 called Otolithus (Gadidarum) elegans, to which species, therefore.
