FISHES. 543 



the Wener's fresh-water fish for many years, but,, when he 

 published his " Scandinavian Adventures/' he had all his spe- 

 cimens over in London, laid them before his friend Mr. 

 Yarrell, and took his opinion; it is odd if two such men 

 could not arrive at something like a just conclusion. With- 

 out, therefore., denying that the two new species which have 

 lately been added to the Scandinavian fauna, and to which 

 I shall hereafter refer, are good and distinct, I for one am 

 inclined to place my faith more upon Mr. Lloyd's opinion 

 in this particular than any other naturalist ; and I therefore 

 take it for granted that these three are good and distinct 

 species, and are the common Scandinavian gwynniads which 

 are found more or less dispersed over the whole face of the 

 country. 



Mlsson, in his " Scandinavian Fiskar " (1855), divides 

 them as follows : 



A. Upper maxillary projecting, or both jaws alike. 



C. oxyrliynchus, L. Stor sik. Of this we have two 

 varieties, very difficult to distinguish from each other 



(a). C. oxyrhynclms, Bloch. Nabb sik. Nose pointed, 

 fleshy, much projecting ; nostrils much nearer the eye than 

 the point of the nose. 



(b). 0. marcena, Bloch (?). Knubb sik. Nose blunt, 

 but still projecting beyond the gape ; nostrils right between 

 the point of the nose and the eye. 



C. lavaretus, Nilss. Prod. Gra sik. La coregone lava- 

 ret, Yal. 



Mlsson's three forms or species are clearly the same* as 

 those described by Mr. Lloyd, for both their descriptions 

 agree in every main point, the only difference between the 

 two being that Nilsson considers Mr. Lloyd's " lof sik " as 

 only a variety of the nabb sik, not a distinct species. I will 

 only refer the reader to the two splendid engravings of these 

 fish in Lloyd's " Scandinavian Adventures," and I think he 

 will agree with me that the difference in the shape of the
