Malakichthys Doderlein, in Steindachner and Doderlein, Denkschr. Akad. 



Wien, vol. 47, 1883, p. 240 (griseus). 

 Satsuma Smith and Pope, Proc. U. S. Nat. Mus., vol. 31, 1906, p. 472 (macrops). 



Form oblong, compressed, head pointed; mouth and eye large; a 

 supplemental maxillary present; villiform teeth in bands, in jaws, 

 and on vomer and palatines; tongue smootii; no canines; a double 

 forward-pointing tooth-like projection at symphysis of lower jaw; 

 preopercle thin toward margin, with evident, but rather weak, serra- 

 tures both above and below the angle; opercle with 2 thin, flat, 

 short spines; gill membranes free; gill rakers long and slender; 

 branchiostegals 7; scales moderate, finely ctenoid, thin, and easily 

 deciduous; opercles, cheeks, and upper portion of head scaly; snout 

 and jaws naked; lateral Ime complete, high, and about parallel with 

 back; tube occupying middle third of scale; two dorsals, connected 

 at the base, anterior with 9 rather slender spines; anal III, 7. Caudal 

 emarginate; ventrals close together, slightly behind base of pectorals, 

 the spine long; pectorals long and pointed, the upper rays longest. 



Known at present only from the shore waters of Japan; one 

 species. 



The affinities of this genus are not certainly known. It has a 

 superficial resemblance to Amia and to Amhassis, but the armature 

 of the opercle is that of the Serranidse. The genus Satsuma was 

 based on a young example of the type of Malakichthys.
