FISHES OF THE PHILIPPINE ISLANDS AND ADJACENT SEAS 83 



entire, edge finely serrate with serrae little coarser below; preorbital 

 entire. Gill rakers 5 + 16, lanceolate, little longer than gill filaments 

 or 2 L 5 in eye. 



Scales 22 or 23 in lateral line to caudal base and 4 or 5 more on 

 latter: 2 above, 6 below, 5 or 6 predorsal, 2 rows on cheek. Tubes in 

 lateral line large, well exposed, each with a small narrow basal scale. 

 Scales with 11 to 13 basal radiating striae; 61 to 81 apical denticles, 

 with 1 to 3 transverse series of basal elements; circuli moderately fine. 



D. VI-I, 9, i, third spine 2 to 2)4 in total head length, first 

 branched ray \% to 2; A. II, 8, i, second spine 2% to 33^, first 

 branched ray 2 to 2^; caudal l^ to 1}{, slightly emarginate behind; 

 least depth of caudal peduncle 2% to V/i', pectoral 1% to 1%; 

 ventral 1% to 1%. 



General color pale brown, slightly paler on under surface of head 

 and abdomen. Sides of head and body with silvery reflections, in 

 some lights lavender to violet. Iris whitish to pale yellowish or deep 

 neutral gray. Usually a deep brown line on middle of side from 

 head nearly to caudal base, parallel with vertebral axis. At caudal 

 base small blackish brown medial spot, greatly less than pupil and 

 separated from dark lateral line. Fins all more or less whitish. 

 Spinous dorsal dusky black over first three membranes terminally. 

 Soft dorsal slightly grayish terminally, end of first membrane behind 

 dorsal spine dusky or dark and about basal third of fin deep brown 

 narrow longitudinal line. Anal paler but with similar dark brown 

 subbasal line. Upper and lower caudal edges narrowly dusky. 

 Many of our examples show a dark rounded spot, little smaller than 

 pupil, above dark median lateral line at shoulder just below tubular 

 lateral line. 



Madagascar, Nicobars, East Indies, Philippines, Biii Kiu, Micro- 

 nesia, Polynesia. This species bears a marked resemblance to Amia 

 hyalosoma. Both appear to be common to brackish water, in the 

 mouths of rivers, estuaries, etc. The black lateral band of Amia 

 lateralis is replaced in A. hyalosoma by a more or less indistinct 

 silvery one and the caudal spot of the latter is larger and the fish is 

 more angular.
