(part) . 



Depth 3; head 3, upper profile oblique. Snout S}i in head; eye 4, 

 1}^ in snout; maxillary reaches Ys in eye, length 2% in head; 8 upper 

 moderate canines, lower teeth all small; interorbital rather low; 

 preopercle border narrow and finely ciliated, edge entire on figure; 

 suborbital depth Iji in eye. 



Scales 46 in lateral line to caudal base, on figure; 4 above, 13 below, 

 1 1 predorsal forward opposite eye center, 5 rows on cheek to preopercle 

 ridge with flange naked ; caudal base finely scaled. 



D. X, 9, 1, first spine elongate and reaches caudal base, second spine 

 V/i in head, eighth ray 1%; A. Ill, 7, i, third spine 2%, last ray 1%; 

 caudal ends in upper filament about long as lower lobe, which nearly 

 equals head, fin deeply forked; least depth of caudal peduncle 2%; 

 pectoral 1 ; ventral 1, ends in filament. 



Red, fins tinted violet. Figure shows golden olivaceous narrow 

 longitudinal bands, as 2 above lateral Une and 7 below. Length, 228 

 mm, and caudal filament 177 mm. (Valenciennes.) 



A doubtful species with questionable locality, though likely of the 



Indo-Pacific. The original figure, however, clearly shows increased 



scales on the cheek so that I feel obliged to let the species fall with 



Dentex. The specific nsime Jilamentosus is in no way invalidated in 



Dentex.
