Bleeker in the dorsal orio-in over the hind eye edge; it is also quite 

 different from both P. zoUingeri and P. trachinoides in coloration. 

 (/cu06s, hunchbacked.) 



APLOACTOIDES, new genus 



Type. — Aploactoides philipphms., new species. 



Body elongate, well compressed, tapers back from head. Head 

 rather small, compressed. > Snout short, obtuse. Eye small, ad- 

 vanced until nearly before center in head length, high. Mouth 

 small, broad, nearly vertical, opens upward. Maxillary very greatly 

 inclined, not reaching eye, expanded behind. Teeth in villiform 

 bands in jaws, very j5ne, bands moderately wide; small band of teeth 

 on vomer, but none on palatines. Preopercle and preorbital armed 

 with several rather long spines. Gill openings wide, free from 

 isthmus. Gill rakers short, low tubercles or papillae. Skin smooth 

 and rather loose, at least on fins. Lateral line high and close to 

 upper edge of back. Head with short, small scattered filaments. 

 Dorsal begins over hind part of eye, first spine larger than those 

 immediately following, and spinous fin much shorter than soft dor- 

 sal. Anal like soft dorsal, only little smaller, both fins connected 

 behind by membrane with caudal peduncle. Caudal elongate, 

 rounded behind. Pectoral long, reaches anal, low, base fleshy. Ven- 

 tral short, fins united about opposite hind edge of eye. 



An interesting genus, differing from Aploactis in its short spinous 

 dorsal and more advanced insertion of the ventrals.

APLOACTOIDES PHILIPPINUS. new species 

 FiGUKE 40 



Depth 3 to 31/2; head 3% to 3%, width IVo to 1%. Snout 31/2 

 to 4 in head from snout tip; eye 5 to 5%, 1% to li/o in snout, I14 

 to li'o in interorbital ; orbit 4 to 43^ in head from snout tip, equals 

 snout, 1 to 11/5 in interorbital; maxillary extends 1/2 to % in snout, 

 expansion II/5 to I1/2 in eye, length 2i/o to 2% in head from snout 

 tip. Gill rakers as 6 + 10 low papillae, barely Vc, of gill filaments, 

 which equal eye. 



Two strong, divergent preorbital spines, posterior much longer 

 and equal eye; 4 preopercular spines, uppermost longest or equal 

 eye. Few short filaments on chin. 



Skin smooth, flabby, or ratlier loosely investing fins. Many fine, 

 short, cutaneous points or flaps on head. Lateral line high, extends 

 along upper part of back, with 14 pores, and apparently reaches to 

 base of last dorsal ray.
