I'ONTINALIS.t 



The origiuiil type of 8. S2)ectabiUs and of ^\ campheUi, the latter being 

 merely a sub.stitute name, is still pp^served in the National Museum. 

 Although biidly decayed, Its identity with the species here called spec- 

 tabilis is evident. The types of Sulmo parkci are now lost, but that the 

 species is the same as S. spectabilis seems unquestionable. The name 

 speGtahills should now be retained for this fish, as the spectabilis of 

 Valenciennes, being a Salar, belongs to a different genus.
