Mariscal Dept. of Biological Science, Florida State University, Tallahassee ABSTRACT Amphiprion nigripes Regan, usually considered a synonym of Amphiprion perideraion Bleeker, is shown to be a valid species of anemonefish. It is redescribed, illustrated, and compared with A. perideraion. Observations on the ecology and behavior of A. nigripes in the Maldive Islands are included. INTRODUCTION Amphiprion nigripes was described by C. Tate Regan in 1908 from a single specimen of 75 mm. total length collected at the Mal-dive Islands. In his short description he states that the species is closely allied to A. melanopus Bleeker and A. perideraion Bleeker, especially to the latter. Leonard P. Schultz revised the genus Am-phiprion in 1953, but neglected to list A. nigripes as either a valid species or synonym. Woods and Schultz (Schultz et al., 1960) in-clude it as a synonym of A. perideraion and under the remarks sec-tion of their paper they state: "Schultz examined the type of A. nigripes in the British Museum and found the pectoral fin to have Library of Congress Catalog Card Number: 78-165189 Publication 1136 93 TME LIBRARY OF TM MM 2 1972 5 1972 ;:i?^i^"««5* "5*'"«)!.?A,'iyil2!?
