" The difi^erences that exist," continues Dr. ParneH 

 " between S. ccecifer (that is, S. Levenensis) and S» 

 /ario, are very striking. The pectorals in S. ccecifer^ 

 when expanded, are pointed ; in S. fario they are 

 rounded. The caudal fin in S, ccecifer is lunated at 

 the end ; in S. fario it is sinuated or even. S. ccecifer 

 has never any red spots ; aS'. fario is scarcely ever 

 without them. The caudal rays are much longer in 

 ccecifer than in fario^ in fish of equal length. In 

 S. ccecifer the tail fin is pointed at the upper and 

 lower extremities ; in S. fario they are rounded. 

 The flesh of S. ccecifer is of a deep red, that of S. fario 

 is pinkish and often white. The cascal appendages 

 in S, ccecifer are from sixty to eighty in number ; in 

 S. fario I have never found them to exceed forty- 

 six." In addition to these distinctions. Dr. Richard- 

 son has remarked that the scales exhibit a small 

 ridge in the centre of each, which he has not no-

 and March. Mr. Wilson states (Ency. Brit.) that
