On page 324, strike out IB. altus, the species having

On page 325, for IB. bubalinitS) substitute IB. cyanel- 

 lus (Nels.) Jor. There seems to be but two valid spe- 

 cies of Bubalichthys, at present known. 



On page 332, Amiurus marmoratus occurs in South- 

 ern Illinois. 



On page 223, et. seg. Generic names ending in the 

 Greek neuter roots "soma," "sfoma," "wma," etc., 

 have been in this work considered as Latin feminine 

 nouns, and the adjective has been made to agree with 

 them accordingly, as "IBoleosoma maculata" "Etheos- 

 tortia flcibellaris" This was done in deference to cer- 

 tain recent authorities in classical matters, who regard 

 such latinized words ending in a as feminine. It is 

 probably better, however, to follow the common custom, 

 and to consider them as neuter, until some other rule is 

 definitely adopted.
