Untv. M?clzigan, 175:l-48, J'igs. 1-2, pl. 1.-Darters are classified in three genera of which Percinu, with nine subgenera and about 35 species, is the rriost primitive, Ammoc~pta , with two subgenera a r ~ d seven species, is highly adapted to a s:uiti habitat, and Etheostoma, with over 100 species, is the most diverse. The Iiistory of classification of darters over the past half century is briefly reviewed, and tlie s111)getlera in current use for Pr?rcina and Awtrnociyptn are adopted. In order to assess phyletic trends, principal differential character states of darters are examined for polarity of prirnitive versus derived conditions. Getius L'theostoma is classified into five groups cotlsistit~g of 18 subgenera. The niost generalized are the Allohistiurn and Litocura groups, each with a single subgenus. The Elheo.ctoirta group consists of subget~era L'tl~eostomc~ s.s. and Ulocmtra. Reinterpretation of the relationship of E. zo~nalr and E. lynceum, with their assigntnet~t o Lthrostomrc LA., dictates resurrection of subgenus Uloc(~ntm for the snubnose darters to replace Nano.ctorno as proposed by Page (198 Ib). The Boleosoma group includes subgettera Bol~momn, Vazllantia, Ion, and Doratioit, with 10 species. Many ot the tnost advanceti darters belong to the Oligocephali~c group o l 10 suhgener-a: Notlionotu.~, Cntor~olus, P.~~~chi-ornu~tor, Oligocefiltcrlzis, Ozarlca, Fu~catelum, Brlophlox, Villom, Hololrpi\, and Mic7-oprrca, with 61 described species. Several sul~getlera rc equivalet~t o those recognized by Page (1981b), but two that were merged witti E. exzle as subgenus Boleichtlzys by Page, Holole/~i.s and Microj~erca, al-e again recognized wit11 the same limits as given for Hololepi~ by Collette (1962) ar~ti Micl-oprrc-a by Bur-I(1978), and E. exilr is assigned to Oli(~ocephalu~. E. okaloosnr, of somewhat cluestionahle status, is also placed in . . Olzgorc~phnl~w. Most of the subgenera, with the possil~le exception of Olzgocrphalw, are I~elicved to be mot~opliyletic hut uncertaitlties r e n ~ a i t ~ as to the interrelation-
