low, oblique, the lower jaw prominent, scarcely projecting beyond upper ; 

 maxillary barely reaching to opposite front of small eye. Upper jaw with 

 a band of villiform teeth, in front of which is a row of strong teeth, about 

 10 on each side, the anterior largest, larger than in most species, but 

 hardly canines. Lower jaw with a single row of rather large teeth , irregu- 

 larly placed much smaller than the larger teeth of the upper jaw ; villiform 

 teeth on vomer, palatines, and tongue. Eye small, placed high and far back ; 

 adipose eyelid small. Cheeks and upper part of opercles with small scales ; 

 rest of head naked. Gill rakers long and strong, as long as eye. Scales 

 rather small ;. breast closely wealed ; lateral line not strongly arched, 

 becoming straight opposite front of anal, its curved part If in length of 

 straight part. Plates on anterior portion of straight part scarcely differ- 

 ent from ordinary scales ; those on posterior portion moderate, with high 

 keels and appressed .spines ; 37 plates in all, counting from beginning of 

 straight part. Spinous dorsal moderate, the spines slender, rather high. 

 Procumbent spine obsolete. Soft dorsal low, falcate in front, the longest 

 ray little more than half base of fin, or \\ in length of head. Anterior 

 part of fin with a distinct scaly basal sheath, which becomes obsolete at 

 about the fourteenth ray. Anal fin similar to soft dorsal, a little shorter 

 and lower, its scaly sheath more developed; free anal spines moderate. 

 Caudal fin widely forked, its lobes subequal, \\ in head, distance from 

 tip to tip more than length of either lobe. Pectorals long and falcate, 

 their tips reaching sixth anal ray, longer than head, and a trifle 

 less than greatest depth of body. Ventrals short, \ length of pec- 

 torals. Coloration in spirits olivaceous ; dark above ; pale below, but 

 nowhere silvery ; top of head clear olivaceous ; opercular spot obsolete ; 

 lower jaw soiled golden ; no pectoral spot ; base of pectoral somewhat 

 dusky ; small irregular dark-brown spots, smaller than the pupil and 

 irregular in size, scattered without order over the body, rather most 

 numerous about pectorals. Caudal fin dusky, especially on its posterior 

 edge ; dorsal and anal dusky, their lobes black ; ventrals dusky at tip ; 

 pectorals olivaceous. Pacific Ocean, about islands in mid-ocean, widely
