The foregoing long list of references to the works of ichthyological authors 

 who have written on the sea trout would seem to demon sti^atc that either wo 

 possess several species, or else that specific names have been bestowed upon various 

 races, or perhaps on the same individuals according to their ages or sexual 

 differences. Anyhow, it is clear that conflicting opinions have existed, and still 

 continue to exist as to the number of forms of sea trout which are pi-esent in our 

 seas and ascend into our fresh waters. At the present day the majority of 

 ichthyologists seem to recognize two species, which I term local races, a northern 

 form which generally possesses a larger number of ca3cal appendages (from 43 

 to 61) than the southern race (from 32 to 52), while the jaws in the former are said 

 to be somewhat less solid than in the latter. Irrespective of the foregoing 

 differences, it is admitted that they pass from one into the other by insensible 



* Also found in Ireland. 



f " The term Eriox as first employed by Albertus Magnus in the 13th, and by Cuba in the 

 IStli century, was considered by Artedi as referring to the common salmon. Linnwus afterwards 

 employed the term as a trivial name to the ' S. maculis cinereis, cauda extremo a-quali ' of Artedi, 

 and the gray of Willoughby and Bay. De La Cepede continued the term in its Linneau sense " 

 (Nat. Hist. Salmon, Edin. Phil. Journal, April 1st, 1825).
