In the present paper is given an account of the tishes of the families 

 of Cirrhitidaj and Aploclactylidtv known to inhabit the waters of Japan. 

 It is based on the collections of Professors Jordan and Snyder, series 

 of which are deposited in the U. S. National Museum. 



KEY TO FAMILIES OF CIRRHITOID FISHES FOUND IN .lAPAN. 



a. Dorsal spines 10, the spinous part of the tin longer than the soft; vertebra' lOi 

 16; eye with a suborbital shelf Cirrhitid^^ 



aa. Dorsal spines 15 or more; the soft dorsal as long as spinous; anal short with 

 acute or incisor-li ke vertebrae more than 10+16; nosuborbital shelf.

Family riRRHITID.F. 



Bodj' compressed, oblong-, covered with moderate scales which are 

 cycloid or ctenoid; dorsal and ventral outlines not similar; lateral line 

 continuous, concurrent with the back, not extending on caitdal; mouth 

 low, terminal, with lateral cleft; eye lateral, of moderate size; pro- 

 maxillaries protractile; maxillaiy narrow, not sheathed by preorbital; 

 teeth small, pointed, sometimes present on vomer or palatines; cheeks 

 without bony suborbital stay; branchiostegals, usually 6; gill mem- 

 branes separate, free from the isthmus; preopercle serrate or entire; 

 opercle unarmed; nostrils double; forehead flattened; no spines or 

 serrations on bones of cranium; second suborbital with an internal 

 lamina supporting the globe of the eye; dorsal fin continuous, long, 

 the spinous part longer than the soft, usually of 10 spines, the spines 

 not depressible in a groove; soft dorsal low; spines rather low and 

 strong; pectoral tin short and broad as in the Cottidis; lower half of 

 fin with its rays simple and enlarged; the membranes deeply incised: 

 ventral fins thoracic, but considerably behind root of pectorals, the 

 rays 1, 5; air bladder large and complicated; pyloric cieca few; 

 skull very compact and solid. Carnivorous fishes of the warm 

 parts of the Pacific; apparently really allied on the one hand to the
