 equal ; teeth on vomer in a very narrow, crescent-shaped patch ; those on 

 palatines in a band much narrower and shorter than that on the vomer. 

 Mouth oblique, the jaws subequal, the lower slightly included. Head 

 scaled forward to the anterior nostril ; scales on cheek in about eight 

 series, those on opercle about as large as those on body, in about six 

 series. Profile straight, from anterior margin of orbit to tip of occipital 

 crest, rounded in front and behind. Eye ij^ in snout, 4>^ to 5 in head; 

 interorbital area a little wider than eye. Preorbital minutely serrate, the 

 serrae weaker than in P. tntcJia. Preopercle with minute teeth on its 

 vertical border, the teeth near the angle sometimes very much enlarged, 

 sometimes little enlarged, more numerous than in P. tnicJia ; serration 

 of the subopercle and preopercle scarcely visible ; opercular spine placed 

 higher than in P. tntcha, its tip sometimes incompletely two or three 

 parted ; a bluntish projection on opercle above the spine. Gill-rakers 

 very short, about equal to one-third diameter of eye, 6 -|- 11. Distance 

 of first dorsal spine from snout 2f to 2t in the length. Height of dorsal 

 spines variable, the first always less' than half as high as the second, the 

 third or fourth dorsal spine highest, 2 to 3 in head, the spines decreasing in 

 height to the ninth ; spinous and soft dorsal connected. Caudal truncate 

 when spread out, emarginate when closed. Anal inserted below the be- 

 ginning of the soft dorsal, its spines graduated, the second thickest ; highest 

 ray about half as long as the head; ventral if in head; pectoral i^i to 

 if in head. 



Scales on the body of about equal size, less strongly ctenoid than in 

 P. tntcha, reduced on breast and head. Lateral line much more strongly 

 curved than in P. true ha.

 those on the lower half of the body scattered with usually a light (blue ?) 

 center, a dusky spot at the base of each scale on the sides ; all the fins 

 dusky, with reddish brown dots; those on the base of the soft dorsal 

 sometimes aggregated into spots. Head 3 to 3^ in length to base of 

 caudal; depth 3 to 3^ ; D. x, 11 or 12; A. iii, 9 or 10. Scales 10 or 

 1 1-54 to 58-19 or 20.
