THE FISHES OF SAMOA. 245 



Ijaiids of villiform teeth on jaws, vomer, and palatines; gill-rakers sharp pointed, the longest less than 

 width of pupil, 14 on lower limb; posterior margin of opercle ending in a spine-like point which 

 extends as a small bony stay across opercle; the posterior limb of preopercle only is serrated; lateral 

 line evenly curved from its origin to a line with posterior axil of dorsal, the straight portion 1.50 

 incurved. Base of spinous dorsal 1.50 in its height, the second (upright) spine being the longest 

 and strongest; base of soft dorsal 1.95 in its length, the soft dorsal spine being equal to base of fin, 

 2.90 in head; base of anal equal to depth of caudal peduncle, its longest ray 1.95 in head; ventrals 

 scarcely reaching base of anal, equal in length to distance from middle of eye to posterior tip of opercle, 

 their insertion being slightly in advance of pectoral; pectoral 1.50 in head, the tip on a line with 

 niiddie of soft dorsal; caudal rounded, 1.20 in head. 



Ocilur in siiirits yellowish white, thickly covered with minute dots; a broad black area covering 

 most of the caudal peduncle, except its upper and lower sides, this black marking extending out and 

 covering the lower half of the caudal fin; anteriorly thi.s color fades out under the posterior axil of 

 soft dorsal; there is a dusky w-ash on upper half of eye and on dorsal surface of head; cheek punctulate 

 with brown dots rather larger than those of body, a small brown spot on opercle near base of the bony 

 stay; sides of thorax rather strongly shaded with brown dots; fins yellowish white. The black color 

 of the lower half of the caudal, which fin is not forked, is very distinctive. 



One specimen from Apia, length 1.75 inches. 



498. Amia zosterophora (Bleeker). New Guinea (Macleay); East Indies. 



499. Amia leptacantha (Bleeker). New Guinea (Macleay ) ; East Indies. 



500. Amia nematophora (Bleeker). New Guinea (Macleay ) ; East Indies. 



501. Amia cookii (Macleay) . New Guinea. 



.Il«i,mn cuok-ii Macleay, Prou. Linn. Soc. N. S. W., V, 1884, 321, New Guinea. 



502. Amia ]iyalosom.a (Bleeker). Puinepetl.; East Indies. 



503. Amia erythrina (Snyder). Hawaii; Samoa. 



Ol this small species we have seven examples from .\pia and Pago Pago. It is clear red in life, 

 often with scattered paler spots, and some dark shading. Our specimens agree well with those from 

 Hawaii. 



A specimen from Pago Pago in life was all deep vermilion red. One from Apia was all bright red, 

 a dusky blotch on opercle, dusky shades along base of first dorsal and on toj) of head; no markings. 



504. Amia doryssa Jordan & Seale, new species. Samoa. 



Apugon hypsdonut^s, Giinther, Fische der Siidsee, 20, South Seas; nut of Bleeker. 



Head 2.60 in length; depth 2.95; eye 2.S5; dor^ial vi-i, 9; anal it, 8; scales 2-26-6; interorbital 

 equal to snout. 



Body oblong, compresssed, its greatest depth at origin of dorsal; body and head scaled; caudal 

 peduncle long, 1.2(1 in head, its depth 2.95; jaws about even, the under one scarcely as long as ujjper; 

 maxillary 1.95 in head, its distal end under posterior margin of pupil; bands of minute villiform teeth 

 on jaws, vomer and palatines; gillrakers sharp pointed, 12 on' lower limb, the longest less than pupil; 

 opercle with three small spine-like projections on posterior margin; both limbs of preopercle with 

 small denticulations; anterior part of lateral line with strong oblique curve under base of soft dorsal; 

 second (upright) spine of dorsal very strong, flat, and sabre-like, its length equal to distance from 

 anterior margin of eye to posterior margin of opercle; shape of the spinous dorsal that of an acute 

 triangle, the base of which is 1.75 in its length; base of soft dorsal equal to orbit; the spine of soft 

 dorsal slightly longer than base of fin, the fin rounded, its longest ray equal to distance from middle 

 of eye to posterior margin of opercle; base of anal 1.50 in length of longest ray; ventrals below base 

 of pectoral, their length 1..50 in head, their tips reaching to base of anal; pectoral 1.40 in head, extend- 

 ing to a line with sixth anal ray; caudal bilobed, the longest ray equal to distance from anterior 

 margin of orbit to posterior edge of opercle. 



Color in life, light brick-red, fins a little darker; no trace of markings. Color in spirits, yellowish 

 white, some black shadnig at base of spinous dorsal; a few small dusky blotches on upper |>art uf 

 opercle; fins without marknigs.
