Genus 44. PHOXINUS. Agassiz. 



Phoxinus, Agassiz, Mem. Soc. So. Neufchatel, 1, 37. 

 Type, CypHnua phoxinus L. =Pbozinua J(8t)i» Ag.

 scales ; teeth 2, 5-4, 2. Length 2J inches.

 complete lateral line. From GhrosomUs erythrogaster it may be best known 

 by the presence of two rows of teeth. 



Habits. — This little fish has been thus far noticed only in Southern 

 Michigan, Southern Wisconsin, and Northern Illinois. It doubtless oc- 

 curs in North-western Ohio. Its habits are probably very similar to 

 those of Teleste-i elongatus.
