Family CIRRHITIDAE 

 By Leonard P. Schultz 



Since publishing on this family in 1943 (U. S. Nat. Mus. Bull. 180, 

 pp. 131-137), I have seen additional specimens, and these have caused 

 me to alter considerably my opinion concerning the generic relation- 

 ships within this family. The key presented here is based on the 

 type species of each genus, with additional species admitted in a 

 few cases. In the footnotes I have listed under each genus additional 

 species examined. Certain species not examined by me are included 

 on the basis of descriptions and figures. 



Neocirrhitcs Castlenau (Proc. Zool. Acchm. Soc. Victoria, vol. 2, 

 p. 101, 1873; type species, N. armatus Castlenau) appears to be 

 related to Hughichlhys Schultz but differs in having the dorsal fin 

 "received in a scaly sheath of the back in which the spines lay alter- 

 nately, forming two rows." I have not seen a specimen, and the 

 description is too incomplete to permit me to allocate the genus.
