E. bipinnulatus. 



Head o\ in body (5 including caudal); depth, 3?. 



D. VI, 1-27-2 ; A. II, 1-17-2. Scales in lateral line about 100. 



Body oblong, elliptical, the back little elevated. 



Head rather long and pointed ; mouth terminal ; lower jaw slightly 

 projecting beyond upper. 



Maxillary triangular, its greatest width, 2\ in its length ; supple- 

 mentary bone long and linear, all except its caudo-ventral margin 

 slipping under preorbital. 



Preorbital and preopercle entire. 



Teeth in both jaws small, conical, equal, narrowing posteriorly ; 

 symphysis bare ; villiform teeth on palatines, vomer and tongue, 

 those on vomer in a diamond-shaped patch with a caudal diverticu- 

 lum. 



Eye 5? in head (41 in smaller) end of maxillary reaching about 

 three-fourths distance from nostril to vertical from cephalic margin 

 of orbit. 



Snout 2f in head. Length of mandible equal to distance from 

 tip of snout to center of .pupil; distance from tip of upper jaw to 

 posterior end of maxillary, 31 in head. Gill rakers about all below 

 angle, cephalic ones gradually shorter, longest about f diameter of 

 eye. 



A slight occipital keel. 



Lateral line Wf»vy, origin at dorsal edge of opercle, the cephalic 

 end of lateral line runs slightly dorsal to opposite origin of spinous 

 dorsal ; here it turns slightly ventral until opposite origin of anal 

 and then median to caudal fin. 



Origin of soft dorsal slightly nearer tip of snout than base of 

 caudal. Spinous dorsal low, the third and fourth spines longest, 

 about 5 j in length of head. Soft dorsal and anal similar, slightly 

 falcate; longest dorsal rays 2 J in length of head, the thirteenth
