By CIIARB.ES L. McKAY. 



The object of this paper is to give a catalogne of the genera and spe- 

 cies of Centrarchida^- recognized by me, in anticipation of a monograpliic 

 review of the family which ! hope to publish at some future time. The 

 results here obtained are based on a study of all the specimens of Cen- 

 trarchidai in the United States National Museum and in the collection 

 of Professor Jordan. Types of nearlj' all the nominal species thus far 

 described have been examined and compared, and I believe that very 

 few of those here mentioned will prove invalid. The species not exam- 

 ined by me are designated hy a star (*). 



J. Genus CENTiiAiicnrs C. & V. 



1. Centrar^ius niacropterus (Luc.) Jor. = C. irideus C. & V. 



The characters assumed to distingush C. maeropterus and C. irideus 

 disappear on examination of a large series. 



2. Genus Pomoxys Kahnesque. 



2. Pomoxys sparoides (L;ic.) Girard. = Cfnfrarchus hexacniifhiis Cuv. & Val. 



3. Pomoxys annularis Raf. 



3. Genus Arohoplites Gill. 



4. Archoplites interruptus (Gid.) Gill. 



4. Genus Ambloplites Eaflnesque, 



5. Ambloplites rnpestris (Raf.) Gill. := '! A. cavifrons Cope. 



o. Genus Acantharchus Gill. 



6. Acantharchus pom.ctis (Buird) Gill. 



* Oncorlninchus chouicha ; O.nerka; Salmn purpiiratiis ; Snli-clin us malma. Sahno irideus 

 does not ranse so far to tlic uortliward. aud Sahno (jairdneri and tlic three other species 

 of Oucorhi/uchuH {kcta kisutch, gorbuscha), do not ascend so far from the sea. — D. S. J.
