backward; a simple tentacle above eye; a branched one on anterior 

 nostril. Mouth broad, inferior, the lips pendalous at angles. Teeth 

 slender, simple, loosely attached ; in a single row, the cutting edge 

 even; strong, curved canines on inner side of lower jaw. Pseudo- 

 branchiae large ; gillrakers on first arch 12, very short, their tips 

 widened and digitate. Lateral line arched over pectoral, ending just 

 above tip of depressed fin. 



Dorsal inserted directly above upper edge of gill opening; con- 

 nected with base of caudal by membrane; a deep notch between 

 spinous and rayed portion; spines much lower than rays, 1.5 in 

 head; longest (middle) rays about equal in length to head. Origin 

 of anal below bases of eleventh or twelfth dorsal spines, not con- 

 nected with caudal, the posterior ray having no membrane back of 

 it; membrane of anal deeply scalloped between the tips of rays; 

 longest ray 1.3 in head. Caudal rounded, the lower rays somewhat 

 more stiff than the upper ones and close together, the fin having a 

 worn appearance on the inferior edge ; middle rays 4.5 in the length. 

 Pectoral obtusely pointed, its length 1.2 in head, the base muscular. 

 Vent ra Is 1.8 in head. 



Sides with 9 conspicuous brownish spots, the anterior ones large and 

 connected by upward extensions which intrude on bases of dorsals, 

 the posterior 2 very small ; indistinct, narrow, dark lines extending 

 along sides; a sharply outlined, blue-black spot on upper edge of 

 opercle; a narrow, slightly curved, vertical band behind eye, and a 

 similar though less distinct one extending downward from eye. 

 Spinous dorsal very dark above and with numerous narrow, elongate, 

 black spots; soft dorsal with small, closely apposed, brownish spots 

 on the upper portion, the lower part with oblique, sharply defined, 

 black lines, interrupted on the rays and growing less distinct pos- 

 teriorly. Anal Avith a broad, dark margin. Caudal with many small 

 pearly spots; the lower border dusky, the posterior white. Pectorals 

 with a few minute, black specks. 



This description is of a brilliantly colored male specimen. Other 

 male examples of the species are duller in appearance, the bands of 

 the sides being indistinct and dark lines appearing on the body. In 

 some cases the anterior spots have ventral projections. 



The females are so different that they might be mistaken for 

 another species. The occipital crest is very low, sometimes scarcely 

 evident ; the dorsals, caudal, and anal are checkered, and the lateral 

 bauds send downward projections on the ventral parts of the sides. 



Keference to a number of specimens gives the following fin for- 

 mula : D. XII or XIII, 20 or 21 ; A. 22 or 23. The species appears 

 to be abundant at Naha, fairly swarming in some of the pools.
