somewhat dark spotted, but cirri on 

 body are usually white; median fins 

 notably dark brown except distally 

 with broad white or pale edges; a pale

 usually an ocellate spot basally on soft 

 dorsal fin at about beginning of last 

 third of its length; background color 

 light tan to dark brown, usually 

 somewhat mottled, a smooth pit or 

 area behind second dorsal spine.

oceans.) A. nummifer (Cuvier) 



16. Dorsal half of first gill arch with the posterior half only bearing filaments; 

 ventral half of first gill arch with gill filaments along its entire length; 

 two dermal cirri on middorsal line of snout in front of base of first 

 dorsal spine; no dermal flap at symphysis of premaxillaries. (Pelagic in

SPECIMEN STUDIED 



Bikini Atoll: Bo by Island, ocean reef, S-46-383, Aug. 17, 1946, Herald, 1 

 specimen, 13.5 mm. 



Description. — Dorsal rays I-I-I-12; anal 7, pectoral 10-10; last 2 or 

 3 soft dorsal rays and last pelvic ray divided ; first dorsal spine a long 

 slender threadlike ray, the bait consisting of a small bulbous knot of 

 filaments; total length of first dorsal spine contained 1% times in 

 length of base of soft dorsal, and almost as long as the slender, free 

 second dorsal spine ; the latter is more slender and elongate than in 

 any other species of Antennarius observed by me. Skin behind base of 

 second dorsal spine smooth; caudal peduncle distinct. 



Color in Alcohol. — Light yellowish gray; a trace of an ocellate spot 

 basally on soft dorsal between rays 8 to 10. 



Remarks. — The slender second dorsal ray of the holotype of A. 

 rosaceus is shorter than that of the Bikini specimen, otherwise there 

 are no notable differences.
