front of the eye, and the posterior ver}^ much larger than the anterior; 

 above the eye a number of small denticles in a single series on each 

 side; distal extremities of the articulars produced into two small 

 spines below; dentaries with two small spines at the symphasis below; 

 edge of preoperculum very long and oblique and the angle very obtuse 

 and rounded; top of head with two ridges between the eyes, the inter- 

 orbital space two-thirds to live-sixths in the eye. Gill-opening very 

 large, its lower margin at least twice that of the upper; gill rakers 

 short, stumpy, rounded, and few; no slit behind the fourth gill-arch. 



Origin of spinous dorsal behind the eye; the spines thick and 

 strong, terminating in long, thread-like filaments, and highest ante- 

 riorly; origin of soft dorsal about over the first anal spine, the fin, like 

 the soft anal, with the posterior rays the longer; anal spines graduated 

 from the first, which is the largest and only a little longer than the 

 eye; pectoral a trifie in advance of the base of the first dorsal spine, 

 about ecjual to the snout, and with its upper rays the longer; ventrals 

 a little in front of the middle of the eye, If to If in body, the middle 

 rays the longest and the innermost the shortest; caudal short, the edge 

 convex, and 2 to 2i in the ventrals. Lateral line much arched in 

 front, descending to the sides posteriorly and then running straight. 

 Caudal peduncle very narrow and compressed, from one-half to three - 

 fifths the eye. Color in alcohol, silvery brown, dark on back and 

 upper part of head, inclining to silver white below; filaments of 

 spinous dorsal brownish black, blotches on the membranes above darlv 

 brown; ventrals, dark brownish, becoming darker distally, the outer 

 portion blackish and with 5 dark blackish cross-bands; caudal with 

 the outer portion with a dusky blotch; body marked with a number of 

 large brownish spots or blotches on the sides, which are most distinct 

 in the smaller examples; in all the specimens traces on sides liehind 

 gill-openings of a blackish, ocellated spot; caudal peduncle dark alunc 

 and 2 dark spots at the base of the side in the 2 small examples. 

 Here described from Misaki specimens; the largest collected by Pro- 

 fessor Otaki measures m inches. 



This species is rare on the coast of Japan, being found in rather 

 deep water. We have two snecimens, one from Tokyo, the other from 

 Misaki.
