Body rather elongate, the caudal peduncle narrow, cylindrical;

'According to Dr. Bleeker, Spheroides spadiceus is distinguished constantly from 
S. lunaris (Schneider) of the East Indies by the longer body, the relatively smaller 
head, the smaller ey6s, the rounded and not angular form of the subocular part of 
lateral line, and by the smoothness of the region behind the tip of the pectoral. One 
of our specimens from Nagasaki has the subooular part of the lateral line evenly 
rounded, while the others have it quite angular.
