Descriptions and analyses of species referable to the genus Amphi- 

 prion have been based on so few specimens, usually only one or two, 

 that the problem of variability or constancy of the color pattern has 

 been neglected. For most of the few hundred species, among more 

 than 50 families studied in detail by Leonard P. Schultz, the basic 

 color pattern has been observed to be fairly constant. It is of utmost 

 importance in recognizing species, especially in the genus Amphiprion. 

 Weber and do Beaufort (Fishes of the Indo-Australian Archipelago, 

 vol. 8, pp. 330-348, 1940) recognized 8 species, whereas we have dis- 

 tinguished 15 species in the tropical Indo-Pacific, and there may be 

 others recognizable when larger series are compared and additional 

 characters studied. 



During December 1953 Schultz had the good fortune to be able to 

 study specimens of Amphij^rion in the British Museum. As the result 

 of these studies certain nomenclatorial changes are necessary in regard 

 to his (1953) revision of this genus. Especially important was the 

 discovery that his new A. mauritiensis is a synonym of A. fusciventer 

 Bennett. 



Fin ray counts were made on various species, including those ex- 

 amined by Schultz in the British Museum, are recorded in table 84. 



Except for original descriptions no attempt was made to include all 

 references to species referable to the genus Amphiprion. Wlienever 

 figures of species were found it has been possible to include these 

 species in the synonj^my, but most species descriptions are not in suf- 

 ficient detail for them to be assigned without an examination of the 

 specimen on which the records were based. The members of this 

 genus normally live a commensal life in sea anemone. 



In the revision by Schultz (1953) of Amphiprion, Ax. latezonatus 

 Waite (pi. 79,A) was omitted. This valid species has been added to 

 the following key after Schultz (1953, p. 189) modified in sections 

 6a and 66.
