(MARGATE-FISH; JALLAO; MARGARET GRUNT.) 



Head 3 ; depth 2. D. XII, 16 ; A. Ill, 7 ; scales 7 or 8-46 to 48-16. Body 

 comparatively deep, the back more elevated and more sharply compressed 

 than in any other of our species, the anterior profile steep and nearly 

 straight from tip of snont to above eye, where a slight angle is formed, 

 the profile thence rising more steeply and forming a somewhat steep curve 

 before the dorsal. In most specimens, especially the larger ones, the con- 

 cavity above the eye is well marked, not, however, in all. Snout long, 

 pointed, its length 2 to 2f in head ; ventral outline nearly straight ; caudal 

 peduncle rather long. Mouth large, the maxillary extending to front of 

 eye, its length 2= to 2f in head, lower jaw included. Teeth not very large, 

 in narrow bands, the autrorse teeth of the posterior part of lower jaw 

 less developed than in some other species; eye small, 5 to 7 in head; inter- 

 orbital space strongly convex, its width 3f in head ; preorbital deep, its 

 least breadth 4 in head ; preopercle finely but sharply serrate, the teeth 

 coarser above. In most of the specimens these serrations are distinct, but 

 in one, not otherwise peculiar, they are scarcely distinguishable. Gill 

 rakers rather small, about 12 below the angle. Scales moderate, those 

 above lateral line not enlarged, arranged in very oblique series; those 

 below more nearly horizontal; soft parts of dorsal and anal covered with 

 thin translucent scales. Dorsal spines rather slender, the fourth highest 

 about 2^ in head ; longest soft rays 5 in head ; caudal lobes subequal, 1^ in 

 head ; anal moderate, its longest rays 4 in head; second anal spine stronger 

 and longer than third, 3 : V in head, reaching past base of the last ray when 

 depressed; first soft rays when depressed not reaching tips of last rays; 

 ventrals If in head; pectorals 1|. Bones of head usually cavernous; 

 mucous canal around preopercle and lower jaw very large; supraoccipital 

 ridge high, extending forward to middle of pupil; temporal crests very 

 low and thin, not extending forward quite to end of supraoccipital crest. 

 Color in life of adult fishes (1 to 2 feet in length) pearly white, some- 

 what olivaceous above, where a few of the scales have very faint dark 

 spots at their bases ; still fainter spots visible along the scales of lower 

 part of sides; mouth orange within; lips and a faint blotch on each side 

 of snout light yellow ; a dusky shade under edge of preopercle (much 

 more distinct in young); fins all light olive; the soft dorsal somewhat 

 dusky ; head without stripes or spots. Young more distinctly spotted, the 

 spots small, round, blackish, each with a pearly edge; one under each scale 

 of back and sides very distinct when the fish is alive, or after its scales are 

 removed, but disappearing almost entirely with death. In life a broad,
