Radii; D. XIX-13; P. 13; V.I-2; A. II-18; first dorsal fin com- 
mencing above the preopercular border, with many of the rays of sub-

curved teeth behind the premaxillaries ; none in the lower jaw. Interor- 
bital space narrow, deeply grooved ; behind the orbits a transverse groove 
behind which the vertex is swollen. <A slender postnareal tentacle, a long 
tentacle above the posterior part of the orbit deeply split into four sub- 
equal portions ; no fringes at its base nor behind the orbit. 
Orbit a little more than one-fourth the length of the head ; the head 
three and a-half times in the length without the caudal fin; depth four 
times in the same.
