Bleeker, they differ in having but 9 dorsal spines; in form and color 
they differ but little, save that in the latter the anal and ventrals are 
blackish, not yellow. The name frenatus was used prior to that of 
inacnmtomus.

Ground color brown or black, with three pearl-colored cross bands, 
the last around the tail; thorax and chin, pectoral, ventral, and caudal 
fins yellow; dorsal fin black. The dorsal fin is scarcely notched and 
has the spines stout and short. The height of the body is rather less 
than one-half of the total length (caudal not included); the caudal fin 
is emarginate. (Giinther.) 
We have not seen this species and adopt the views of Dr. Bleeker 
and Dr. Giinther as to its synonymy. The species must be rare in 
Japan, having been taken only at Nagasaki and in the province of Kii. 
The variations in color indicating local or other varieties have been 
indicated as follows: 
a. Ventrals and anal yellow: polymnus. 
aa. Ventrals and anal dusky or black; pectoral half black: chrysargurna. 
aaa. Ventrals yellow; anal black: clarkii. 
aaaa. All the fins black: hoholensis. 
aaaaa. Ventrals and anal edged with black: japonicus. 
In case these forms should prove distinct species, the Japanese form 
would stand as Am.phiprkm japmiieus.
