STUDIES OF CERTAIN APOGONID FISHES FROM THE 

 INDO-PACIFIC, WITH DESCRIPTIONS OF THREE NEW 

 SPECIES 



By Ernest A. Lachner 



A Faunal study of the Apogonidae of the northern Marshall 

 Islands brought to my attention many taxonomic problems involving 

 certain species of the family distributed elsewhere in the Indo-Pacific 

 region. The present paper, a result of this study, includes : 1, A review 

 of the genus Archamia; 2, studies of the Apogon bandanensis group ; 

 and 3, studies of the genus Paramia. Three species are described as 

 new. 



I wish to thank Donald S. Erdman, formerly of the United States 

 National Museum, for certain field notes; Dr. Ethelwynn Trewavas, 

 of the British Museum (Natural History), and Prof. L. Bertin, Mu- 

 seum National d'Histoire Naturelle, Paris, for correspondence con- 

 cerning type specimens ; and Dr. J. L. B. Smith, of the Rhodes Uni- 

 versity College, Grahamstown, South Africa, for kindly providing 

 data and specimens of Archamia from Africa. I am indebted to the 

 staff of the Smithsonian photographic laboratory for the photographs. 



METHODS OF COUNTING AND MEASURING 



The last ray of both the soft dorsal and the anal fins, divided to 

 the base, is considered as one. All rays of the pectoral fin are counted, 

 including the very small unbranched one at the lower end of the fin 

 base. The count of lateral-line scales includes all scales on the body 

 from the upper edge of the gill opening along the lateral line to the 

 end of the hypural at the base of the caudal fin rays. The scales above 

 the lateral line are counted downward in a posteriorly oblique row
