The annotated check list grew to 15 taxa with the addition of Opisodasys vesperalis (Jordan) and Chaetopsylla setosa Rothschild, both new for Alaska: Tarsopsylla octodecimdentata coloradensis (Baker), new for southeastern Alaska; and an Oropsylla sp. Nine species of wild mammals and the domestic cat are reported as hosts of fleas in southeastern Alaska for the first time, increasing the total number of mammalian hosts to 25 identified species. Seventy new records for 10 islands and the mainland are combined with published records in a distribution table. Morphological variations in the posterior margin of sternum VII of females of Monopsyllus ciliatus protinus (Jordan) and distinguishing characters of three other taxa are illustrated
