streaks; fins pale; edge of opercle dusky. Coast of Peru; not rare; said 

 to have once been taken at Mazatlan. We have examined several speci- 

 mens 1'roui Callao. It has the central pore at the chin, the failure to find 

 which led Kner to place the species in Diagramma. It seems to be identical 

 with Peters' type of P. notatum, preserved in the museum at Berlin, though 

 it disagrees with Peters' description, the dorsal rays being XII, 15, not 

 XVIII-I, 15, as stated by Peters. This species is probably the one poorly 

 described by Tschudi under the name of Pristipoma scapulare. It is well 

 distinguished by the color mark, which has suggested the names scapularis, 

 melanospiltis, and notatus. (scapula, shoulder, from the shoulder spot.)
