SALMONES, 



BY JOHN RICHARDSON, M.D., F.R.S., &c. 



The following notices of four specimens of trout, brought from Boothia Felix 

 by Captain James Clark Ross, are drawn up in very general temis, that they 

 may not occupy more space than that assigned to the other objects of Natural History, 

 described in the Appendix ; but figures, with the characters of the species in minute 

 detail, will be given in the third volume of the " Fauna Boreali Americana," now 

 preparing for publication. 



The first species is, as far as we know, peculiar to the inlet in which it was found. 

 It would have been highly interesting to have detected the same species of salmon 

 in Coronation Gulf and Regent's Inlet, but the Salmo Hearnii and Mackenzii, and 

 several species of Coregonus, found in the former, were not seen in the latter; neitlicr 

 have the S. salar, or common salmon, which frequents the rivers from Labrador to the 

 forty-second parallel of latitude, nor an undescribed species, resembling the Gorbuscha 

 of Kamtschatka, which abounds in New Caledonia, been hitherto detected in the 

 American Polar Seas ; nor does the .S*. riamaj/cush (Pennant), a gigantic trout, which 

 exists abundantly in all the great American lakes, appear to have been observed in 

 the waters of Boothia Felix. The last species, however, that is mentioned in the 

 following notices, is common in all parts of the fur countries ; and it is probable that 

 .V. nlipes and nitidus have also an extensive range, though want of more southern 

 specimens have prevented us from ascertaining the fact.
