Head 8 in leng'tli, without caudal; depth 4^. Dorsal lX-20; anal 

 17; pores of lateral line 37. Eye 5 in head; inter orbital space 7i, bone 

 only 12; snout 3f ; maxillary 2i; height of caudal peduncle 51. 



Lower jaw included, snout li to li times longer than eye; maxillary 

 reaching to behind pupil, scarcely to posterior border of orbit. Small, 

 conical, sharp teeth in narrow bands on jaws, vomer, and palatines, 

 smaller than in P. japonicus or P. jjercoldes; the premaxillary band 

 not so much widened in front; slightly than the bands on mandible; 

 teeth on vomer and palatines equal in size; the vomer projects below 

 the level of the palatines. Preopercle with a small sharp spine at 

 angle, a \qv\ small, blunt, antrorse spine, covered by the skin, at 

 lower anterior edge, and a couple of slight scollops on posterior edge. 

 Nasal spines obsolete. Superorbital tentacle small and flat, shorter 

 than pupil; small nasal tentacles present. Interorbital space rather 

 narrow and deep. 



Spinous dorsal elevated in front and with a rounded notch at its 

 middle; the first and second spines much closer together at their base 

 than are the others, the latter higher than the other spines, its length 

 2f in head, the first, the next highest, only slightly higher than the 

 third, 3|; the fourth much shorter, 3f ; the fifth and sixth slightly 

 higher; the fin rounded behind. The soft dorsal higher than the 

 spinous, the longest rays 2| in head; the last ray is connected to caudal 

 peduncle b}" a membrane; the tips of the last ray reach slightlj^ past 

 those of anal. Anal much lower than soft dorsal, the longest rays 3f 

 in head. Pectoral with 13 rays, the lower 8 swollen, the uppermost 

 of which is the longest, and reaches a little past front of anal, its 

 length li in head. Caudal rounded, its length If in head Lateral 

 line with a strong double curve anteriorly, .stronger than in other 

 species. A row of small bony plates sometimes present above pectoral; 

 skin otherwise naked. 



Colo)'. — Brown above, bell}' and under parts white; back above lateral 

 line with dark cross bands; the first at front of spinous dorsal; the 

 second just behind middle of spinous dorsal, the third under front of 

 soft dorsal, the fourth under middle of soft dorsal, the fifth under 

 sixteenth to eighteenth ra3's on the caudal peduncle; the sides below 

 lateral lines mottled with irregular dark blotches; a dark band run- 

 ning anteriorly from nape through eye across maxillary, involving the 

 iiis; a dark band less conspicuous and more broken, running from eye 

 backward across cheek following upper edge of suborbital stay; 

 spinous dorsal dusky except on area at center, which is transparent; 

 soft dorsal and anal with 6 to 7 dark cross bands running obliquely 

 across rays from their tips slightly backward and upward toward
