NEW FISHES 227 



General shape much as in A. ocellatus ; body compressed poste- 

 riorly ; breast and lower jaw tumid ; head wide, the width one and one 

 third in length ; mouth dorsal with the cleft vertical and the mandible 

 armed at the symphysis with a knob, projecting beyond the pre- 

 maxillary ; mandible long, one and three fourths in head, naked, the 

 posterior one third hidden beneath a deep fold of the skin ; teeth small, 

 in villiform bands in both jaws, and on vomer and palatines ; head 

 without large fleshy filaments about angle of mouth and mandible ; 

 gill-openings small, without naked areas surrounding them ; situated 

 below and slightly posterior to waist ; head, body, fin-rays and spines 

 armed with small bifid spinules, lacking only on premaxillary, max- 

 illar}' , margin of mandible, first dorsal spine, depression behind second 

 dorsal spine, five supraocular pits, fin membranes and on underside of 

 pectoral and ventral rays ; spinules widely forked, with a small ten- 

 tacle, exceeding the spines in length, between each two ; first dorsal 

 spine slender, filamentous, terminated by a cluster of long filaments 

 which are arranged in two more or less distinct clusters. Filaments 

 more than two thirds the length of stalk, which is slightly shorter than 

 second dorsal spine ; second dorsal spine thickened, low, curved down- 

 ward at apex, followed by a deep, smooth depression ; third dorsal 

 spine higher and heavier, membrane deeply incised in front of the soft 

 dorsal ; soft dorsal subrounded, much higher than spinous part, ninth 

 and tenth rays highest, exceeding slightly the maxillary ; first ray 

 short, truncate at tip, posterior rays reaching beyond base of caudal ; 

 anal fin similar to soft dorsal, but more rounded and slightly lower ; 

 pectoral fin geniculate, subrounded, some of upper rays longest, one 

 and two fifths in head ; ventrals rounded, one half length of pectorals, 

 situated below posterior border of eye ; inner ray divided ; caudal evenl}- 

 rounded at tip, rays all divided, length slightly less than pectorals. 



Coloration in Life. — Above pinkish or flesh-color, spotted and 

 streaked with light and dark olive-brown ; a small unspotted area 

 above pectoral, below creamy with dark olive-brown spots ; chin and 

 snout faintly dark spotted ; orbit below and posteriorly with radiating 

 dark streaks ; first dorsal spine light with dusky cross bars, second 

 and third spines without dark spots ; soft dorsal spotted like back, anal 

 fin similar; pectoral and ventral fins immaculate below, dusky, dark 

 spotted above ; caudal fin with two series of dark spots on membrane 

 running vertically through fin ; iris light golden-brown. 



This species is nearest to A. ocellatus^ differing in the coloration, 

 the bifid filaments of the first dorsal, and the lack of dermal flaps on 

 the head, at the angle of the mouth and on the mandible.
