anal ray 2 to 2XoJ caudal 1% to 1^4, hind edge slightly emarginate, 

 upper lobe often little longer; least depth of caudal peduncle 2 to 

 2%; pectoral 1}4 to \%; ventral \% to \y%. 



Light brown generally, becoming paler to whitish below, especially 

 on abdomen and lower surface of head. Head largely brownish above. 

 Iris pale or whitish to deep neutral gray, with dark lateral band 

 crossing. Dark brown line follows along edge of back along bases of 

 both dorsals. Second narrow dark brown line from above eye 

 anteriorly to upper surface of caudal peduncle anteriorly, where fad- 

 ing out. Third broad horizontal deep brown band from snout tip 

 through eye and midway along side to caudal base, though behind 

 eye band narrowing considerably and fading behind. At caudal base 

 and slightly above middle small round black spot, much smaller than 

 pupil and just above tubes of lateral line. Median dark predorsal 

 line from origin of spinous dorsal forward to middle of interorbital. 

 Dorsals grayish-brown, also caudal, other fins paler to whitish. 

 Larger dorsal and anal spines burnished with silvery. 



Rod Sea, Natal, East Indies, Philippines, Micronesia, Polynesia- 



Our numerous examples all agree in the type of coloration described 

 above. In this they differ from Bleeker's figure of Amia chrysojjoma 

 as that shows only one dark longitudinal line, which extends from 

 above the eye to the caudal peduncle above. Also he shows some 

 dull orange spots on the lower side of the head and three rows of 

 scales on the cheek. Bleeker's figure of Amia moluccensis is without 

 any of the usual markings, the spinous dorsal terminally blackish 

 and the cheek with four rows of scales. An examination of the exam- 

 ple reported as Amiafusca and figured by Jordan and Seale shows it 

 to belong to something different. 



Four of our examples from the Cataingan Bay series, 91 to 108 

 mm. long, taken April 17, 1908, show them to belong to the peculiar 

 condition of buccal incubation. Each has its mouth and pharynx 

 crammed with eggs, some in a well developed stage toward hatching. 

 All these appear to be males. They were easily recognized among 

 the series of specimens by their rather full throats.
