■' Thfimallus ontarivnsis Cuvier «fc Valenciennes, XXI, 4.'')2, 1648 (specimens sent by 

 Mill Hit from Lake Ontario)=T/ii/niaZ^/s tricolor Cope. The following is a translation 

 of Valenciennes' account: We have received from Lake Ontario a Thymallus very 

 near to that of the lake of Geneva. It has, however, more naked space under the 

 throat, although less than in Thymallus gymnothorax. The head is evidently more 

 pointed, the body more elongate, the dorsal a little longer. The denticulationsof the 

 scales are more pronounced. The colors seem scarcely to differ from those of Thymal- 

 lus. iov our specimens are greenish, with a dozen gray lines along the flanks. The 

 dorsal has 4 or 5 lougitudiual streaks of red. Our specimens are a foot long ; they 

 have been sent by M. Milbert. ( Valenciennes I. c.) 



3 The original diagnosis of Stenodus is said to be in "Appendix Bach's Voyage. Rept. 

 N. Aui. Zool., 1836." 



According to Dr. Bean, our species is probably not distinct from the Asiatic species, 

 S. lencichthys (Guldenstadt).
