Diagnosis |
Resembles P. fenestratus in form and in ecology, but differs from it in having a larger eye and consequently narrower preorbital, in the more numerous teeth in the upper jaw and on the lower pharyngeal, the higher number of gill rakers, the anterior of which, although short, are acute and well defined and in the higher modal number of dorsal spines. Differs from P. virgatus in the absence of enlarged pharyngeal teeth. |
