Head large, compressed, with subvertical <-he(^ks, snout short and high, wilhont preocular 

 depritssion. The si)ecies thus more closely re.seudjles the small brightly colored Sfhasldpisli-n from tlie 

 Houth Seas than it does other species of Scorp:ai.oj)s!s. (!)ccipital fossa moderate, quadrate; a shallow 

 pit below the eye; eye large, prominent, slightly larger than snout, more than twice width of interor- 

 bital space, which is deeply concave, its floor with a pair of inconspicuous ridges which do not cross 

 the occipital fossa; at outer edge of each of these ridges near middle of interorbital space is a pair of 

 conspicuous mucous pores; preocular, supraocular, postocular, tympanic, parietal and nuchal spines 

 I)resent, th(! tympanic duplicated (a.s an irregularity) in the type; parietal and nuchal spines not in a 

 line with the others; a group of small prickles innncdiately behind eye on a level with upper end of 

 gill-slit; behind these a ridge terunnating in a spine, succeeded by the similar suiu-ascapular ridge and 

 spine; between the latter and the nuchal sjiine an oblique crest bearing several small spines; subocular

crest low and sliar[), with 4 low spines directed luu'kward, each terminating a short secondary crest, 

 the anterior 2 a little below the main ridge; upper preopercular spine short and strong, larger than the 

 others, in line with the subocular ridge and bearinga smaller s))incat its base; four short spinous points 

 below upper preopercular spine, regularly graduated from above; margin of preorbital with 2 strong 

 divergent sjiines, the posterior compressed and much larger than the anterior; preorbital also with a 

 small spine directed upward and backward toward eye; below U[)per opercular spine a number of sub- 

 sidiary spines and ridges: one or more small spines and ridges ma>' also develop below lower opercular 

 ridge; tiroad cutaneous flaps present on anterior nasal tube, and on supraocular, parietal, preorbital, and. 

 lower preopercular spines; a few accompany lateral line, and a small number are scattered on trunk, 

 sides of head, maxillary and mandible; supraocular flap very long in the type, the margin variouslv 

 cleft, nearly reaching front of dorsal when dei)ressed; it is subject to great variation in its develop- 

 ment, and is scarcely to be distinguished in some of the cotypes; ma.xillary wide posteriorly, reaching 

 vertical from posterior edge of orbit; teeth in moderate bands in jaws, in a very narrow band (aliout-2 

 series) on vomer; palatines toothless; no trace of pore or slit behind fourth gill-arch; gill-rakers very 

 short liarely movable, with enlarged spinous tips, 7 or s on boi-izoutal lindi of anterior an'h.
