Head 3^ in length; depth 4. D. Ill, XXVI, i; A. II, 19. Scales 2-35 or 

 36-11. No variation was found in fin and scale counts in five specimens. 



Maxillary reaching a point behind vertical firom orbit, half length of head in 

 the type, which is a male; in females the maxillary is much shorter, not reaching 

 beyond the eye, and is less dilated at its extremity. Orbital tentacle narrow at 

 the stem-like base, the distal half divided into 4 to 6 fringe-like filaments, the 

 entire length half the vertical diameter of the orbit. A pair of similar, 

 slightly shorter nuchal tentacles. Anterior nostril in a short tube, the poste- 

 rior margin produced into a slender filament. Jaws with small conical teeth, 

 the outer series slightly enlarged. The premaxillary teeth are mesially in a 

 wide band, which narrows laterally into a single series continuous with the 

 outer series of the band. One or 2 pairs of the inner mesial teeth of the 

 premaxillary band are enlarged and directed almost horizontally backward. 

 The mandibular teeth are similar to those in the premaxillaries, but form a 

 narrower band anteriorly, with a longer single row along the side of the man- 

 dible. A single row of teeth on the vomer, similar to the outer series in the 

 jaws; no palatine teeth. The mandibular symphysis projects slightly beyond 

 the premaxillaries. 



The head is naked, the body covered with large smooth scales, which are 

 reduced in size on the nape and the abdomen; fins naked. 



The origin of the dorsal fin is vertically above the margin of the preopercle. 

 The anterior dorsal lobe is low, the first 3 spines shorter than any succeeding 

 spines except the fourth. The notch between the third and fourth spines is 

 comparatively shallow, the membrane joining the front of the fourth spine at 

 about the middle of its height. The front of the anal fin is about midway 

 between tip of snout and base of caudal (somewhat variable in position in 

 other specimens, in which it may be slightly nearer either to the tip of the 

 snout or to the caudal). 



Color in spirits, light brownish gray, the sides with 7 or 8 rather faint broad 

 brown crossbars, which are continued on the dorsal fin. In the interspaces 

 between the bars are scattered small white spots. A narrow dark bar at base 

 of caudal. An irregular non-ocellated black blotch on the first 2 dorsal 

 spines. An ocellated spot much larger than the eye on the basal portion of 

 the twenty-first to twenty-fourth dorsal spines. A variable number of 

 smaller ocellated spots in front of this, sometimes i for each dark crossbar. 

 Anal fin with oblique dark and light bars of nearly equal width. In the 

 females the lower side of the head and the preopercular margin are finely 

 speckled with white and brown, and the paired fins are finely crossbarred. 

 In males these regions are plain.
