The foregoing long list of references to the woi'ks of ichthyological authors 

 who have written on the sea trout would seem to demonstrate that either we 

 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 present 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, o northern 

 form which generally possesses a larger number of ca-cal appendages (from 43 

 to 01) 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

f " The term Eriox as first employed by Albertiis Magnus in the 1.3th, and by Cuba in the 

 15th century, was considered by Artedi as referring to tlie common salmon. Linnanis afterwards 

 employed the term as a trivial name to the ' S. maculis cinereis, cauda extreme a>(iuali ' of Artedi, 

 and the ;;?«7 of Willoughby and Kay. De La Cep(5de continued the term in its Linnean sense "
