This fish is readily distinguished from E.porocepluilus, Cuv. & Yal., 

 by the considerably smaller scales of the neck. The latter is doubt- 

 less identical with E. ophiocejihalus, Kuhl & v. Hass.

 obtuse, flat, depressed. [The diameter of the eye is one-fourth of 

 the length of the head, in an immature specimen.] The maxillary 

 reaches to below the posterior half of the eye. Teeth in N-illiforra

 the second dorsal and the anal. Head entirely scaly, except the
