Zusammenfassung:A conodont fauna from the Coronados Islands, southeastern Alaska, consists of the new taxa Polygnathus churkini n. sp., Polygnathus bucareliensis n. sp., Polygnathus aspelundi n. sp. and Polygnathus xylus pacificus n. subsp., together Polygnathus aff. P. dengleri Bischoff & Ziegler and Pandorinellina insita (Stauffer). The fauna is considered to be of early Late Devonian, and most probably of early Frasnian age (Lower asymmetricus-Zone).
