the two limbs of preopercle distinctly denticulate; the lower posterior limb of preorbital denticulate; 

 gillrakers rather sharp pointed, the longest scarcely equal to pupil, 17 on lower limb; second dorsal 

 spine much the strongest, its length 2 in head; base of soft dorsal 3 in head, its longest ray 1.80 in 

 head; anal rounded, its base 2 in its length, the second spine 2.25 in head, its longest ray 1.75 in head; 

 pectoral 1.45 in head, its distal end below middle of soft dorsal; ventrals reaching base of anal, their 

 origin directly below origin of pectoral; caudal bilobed, 1.50 in head. 



Color in spirits, light brownish; a black half-band at origin of spinous dorsal extending to beneath 

 anterior third of pectoral; a second black band at origin of soft dorsal, extending down to lateral line; 

 a third black band at posterior axil of soft dorsal, longer than second band, extending to below lateral 

 line, in young examples extending to middle of anal base; a third very indistinct dark band over 

 middle of caudal peduncle (in an old example this is broken up into three or four round spots) ; a 

 distinct round spot on lateral line just anterior to base of caudal; a round black spot on opercle; a dis- 

 tinct black line from eye to angle of preopercle; anterior dorsal spine black, upper and lower margin 

 of caudal dusky; tip of ventral and anal with dusky wash; pectoral vellow. 



Fig. 3*1. — Autia koilomatodon (Bleeker). 



Color in life of a very large specimen from. Pago Pago, dark reddish olive brown; a faint darker 

 bar under first dorsal, one under second dorsal; a small round blackish spot at base of caudal, and one 

 on opercle before its edge; iris golden. Fins all dusky brownish red, the first dorsal darker; dorsal 

 rather dark; dark dots confluent along base of soft dorsal. Caudal lunate; dorsal vi. 



Another large specimen from Pago Pago was dark olive brown in life, much mottled, with three 

 vague dark cross-bands; a large black spot on opercle and another at base of caudal ; fins mottled brown. 



We have eight specimens from Apia and Pago Pago, of a large and robust species of Amia, 

 evidently allied to Amia koilomatodon. It has a distinct caudal spot, which is said to be wanting in the 

 latter, but as no other differences appear, we refer our specimens provisionally to Amia koilomatodon. 

 The specimen described is no. 51733, U. S. National Museum, 5.63 inches long.

 Apogon fasciatus Gunther, Fische der Siidsee, 19, tat. 20, fig. A. 



This species very closely resembles Amia novemfasciald, hut the colors are deeper, and the black 

 bands, broader and continuous, do not extend on the caudal fin. There is no black spot on base of
