Depth of body z\ to 2g in the length, length of head about 3J. Snout longer 

 than eye, diameter of which is 4i to 5 in length of head ; eyes separated by a concave 

 space, its width J to J diameter of eye : lower eye a little in advance of upper. 

 .Maxillar\' extending to below- anterior edge of eye or a little beyond, length about 

 i\ in head : lower jaw ij to if in head. Teeth of upper jaw very small and close-set 

 laterally, becoming stronger and wider apart anteriorly ; lateral teeth of lower jaw 

 somewhat stronger and wider apart than those of upper. Gill-rakers " palmate " 

 (short, broad, the margins strongly spinulate) : 8 or 9 on lower part of anterior arch. 

 Scales feebly ctenoid on ocular side, cycloid on blinrl side ; 45 to 50 in lateral line. 

 Dorsal 77-83 ; first rav somewhat prolonged and expanded distally .\nal 56-62.

Pectoral of ocular side with 9 to 11 rays, length about i head. Caudal rounded or

This .species is provisionallv placed here, but perhaps represents a distinct genus. 

 It mav be distinguished from all species of Arnoglossiis by the form of the gill-rakers, 

 which' are similar to those of certain .species of Pscudorhombus, and from most of them 

 by the concave interorbital space.
