Species distinction. Differs from A. aculeatus by absence of subcaudal spines, less deep body (see regressions, body dcptli, Tables 8 and 10), lower dorsal spine, higher \'ertebral count and post- abdominal spine characteristics; differs from A. lychnus by presence of enlarged canines, lighter pigment, no subcaudal spines, preopercle and post-temporal spine characteristics and first anal photophore; differs from A. sladeni by presence of enlarged canines; no definite pigmented.
