Grayish, thickly mottled with darker and somewhat translucent; 
four large, horizontally-oblong, black ocelli, each surrounded by a 
l)inkish area; one just behind middle of the body below the dorsal, 
one opposite this above anal; two similar smaller spots below last 
rays of dorsal ‘and above last of anal. Body comparatively elongate, 
strongly compressed. Eyes large, nearly 4 in head, separated by a prom- 
inent narrow, sharp ridge. Upper jaw with very numerous small, close- 
set teeth laterally, and 4 or 5 canines in front; the lateral teeth abruptly 
smaller than the anterior; each side of lower jaw with 7 to 10 teeth. 
Chin prominent. Mamillary narrow, reaching past middle of pupil, 2^ 
in length of head. Gape curved. Scales weakly ctenoid or cycloid. 
Gill-rakers thick, rather long, few, about 8 below angle. Dorsal low, 
beginning over front of eye, some of the anterior rays exserted, but not 
elongate; the longest rays behind middle of tin, not quite half head.

Brownish olive, with four large, oblong, ocellated spots, the first above

triangle, the hindmost being on the lateral line. Body oval, com-

*A specimen in our coBection from Wood’s HoB, Mass., provisionally referred to 
this species, shows the following characters: 
Brownish, somewhat mottled, without traces of ocelli (possibly faded); fins similar. 
Body rather elongate, slenderer than in other species and more compressed; mouth 
rather large, oblique, the lower jaw not projecting, the maxillary 21 in head, reaching 
to opposite jmsterior border of pupil ; about 12 teeth on each side of lower jaw, the an- 
terior rather long, about equal to anterior teeth of upper jaw ; lateral teeth of upper 
jaw becoming gradually smaller posteriorly, much larger, less numerous, and more 
widely set than in other species of this genus. Eyes large, longer than snout, 4 to 4^ in 
head, separated by a n.arrow, elevated, bony ridge, narrower than pupil; anteriorly 
scaleless, and curved behind the upper eye posteriorly. Scales moderate, cycloid, 
rather thin; curve of lateral line 4f in straight part. Gill-rakers 2-|-8iu number, 
rather long and slender, about 4| in maxillary. Dorsal beginning above middle of 
eye, its anterior rays not longer than others; the middle rays a little longer than 
longest of anal, which are about half head; caudal as long as head; anal spine ob-
