The length of the head is one-fifth of the total ; the pectoral fin

Pic (Lake Superior). 



This fish may prove to be the same species as Boleosoma tessel- 

 latum. 



* Agassiz (Lake Super, p. 299) refers to this genus Etheosfotna olmstedi, 

 Storer (Boat. Joui-n. iv. p. 61. pi. 5. f. 2). Agassiz also gives the diagnoses of 

 two other genera, closely allied to the above, Ethcoitfoma and Pacil<isoma. AH 

 these small fishes from North America are too little known to admit of their 

 separation into a family [Etheostomufu. Ag.). Pikoma has a great resemblance 

 to Liiciiiperca.
