new species among this family, and I do not believe that over four* dif- 

 ferent kinds are to be found in this upper country'.

A REVfEW OF THE «ENERA AND SPECIES OF THE FAiTIII.V CErV- 



TRARt'HB» E, WITH A OESCRIPTIOX OF OIVE .^E\V SPECIES. 



By Clf ARI.es I.. McKAY. 



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

 cies of Ceutrarchidie recognized by me, in anticiijation of a monographic 

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

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

 trarchidte in the United States National Museum and in the collection 

 of Professor Jordan. Types of nearly all the nominal species thus far 

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

 few of those here mentioned will i^rove invalid. The species not exam- 

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



1. Genus CENTRARCiirs C. & V. 



1. Centrarcluis macropterus (Lac.) Jor. = C. irideus C. & V. 



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

 disappear on examination of a large series. 



2. Genus Pomoxys Eafinesque. 



2. Pomoxys sparoides (Lac.) Giraril. = Cenfrarclnis licxacaiiflnis Cuv. & Val. 



3. Pomoxys annularis Raf. 



3. Genus ARcnoPLiTES Gill. 



4. Archoplites interruptus (Grd.) Gill. 



4. Genus Ambloplites Bafinesque. 



5. Ambloplites rupestris (Raf.) Gill. = ? A. cavifrons Cope. 



5. Genus Acantharchus Gill. 



6. Acantharchus pomctis (Baird) Gill. 



* Oiicorlii/nchus chouicha ; O.nerlca; Salmo purpuratus ; Salrclinus malma. Salmo irideus 

 does not range so far to the northward, and Salmo (jairdncri and the three other species 

 of Oncorhynchus {Iccta kisuich, gorhuscha), do not ascend so far from the sea. — D. S. J.
