Vertebrae. 57. Dentition. Premaxilla with about 80 small, pointed, retrorse teeth. Dentary with about thirty outer, smaller pointed teeth and nine inner, long, barbed, depressible teeth, the second and third being the largest. Left palatine with three large, barbed, depressible teeth, these being set somewhat inward from a row of eight small, pointed teeth. Lingual teeth fourteen, moderately compressed, the first the largest, the remainder gradually decreasing in size. Gill-teeth. The first gill arch bears a series of closely set, small, pointed gill-teeth. Colour (in spirit). Dark brown above the lateral line, medium brown below, except where the black peritoneum of the body cavity shows through the abdominal walls. The fins are more or less hyaline, except for the caudal, which has a fairly dense covering of small melanophores. There is a kidney-shaped iridescent area on the outer walls of the optic cup of the eye, close to the lens. This has been regarded as a luminescent organ, but it must be the elliptical mass of fibrous tissue
