 434 in head from snout tip; eye 334 to 3^, greater than snout or 

 interorbital; maxillary reaches % to % in eye or about opposite hind

Scales 23 or 24 in lateral line to caudal base and 3 or 4 more on 

 latter; 2 above, 6 below, 3 or 4 predorsal, 2 rows on cheek. Tubes 

 in lateral line large, well exposed, each with small crenulated basal 

 scale. Scales with 16 to 18 basal radiating striae; 73 to 118 apical 

 denticles form an alternate series or with 2 or 3 transverse series of 

 basal elements; circuli fine but none apical. 



D. VII-I, 9, 1, fourth dorsal spine 2}<i to 2% in total head length, 

 second dorsal ray \% to 1%; A. II, 8, 1, second spine 3% to 4, first 

 branched ray 2 to 2^; caudal 1)4 to 1 3^3, hind edge emarginate; 

 least depth of caudal peduncle 2% to 2%; pectoral 1% to 1%; 

 ventral 1% to 2Xo. 



Largely light brown, sides of head and trunk with dull silvery to 

 brassy tints. Slightly diffuse pale streak follows along in lateral 

 line and another parallel with vertebral axis laterally. Brown band, 

 including end of mandible and snout extends to eye and faintly 

 reflected on postocular. Small black median spot, less than pupil, at 

 caudal base and sometimes reflected as diffuse dark bar above and 

 below. Fins generally all pale, on spinous dorsal broad dusky band 

 obliquely from front edge up till behind fifth spine, also subbasal 

 deep brown line on soft dorsal and usually another along anal sub- 

 basally but most distinct posteriorly. Iris pale or brassy to brown 

 or neutral gray. 



Known only from the Philippines, we having the following series 

 listed below. It is one of the paler and less contrasted forms 

 though fairly constant in color pattern. Several males with the 

 thorax swollen, also the mouth cavity, evidently having just com- 

 pleted buccal incubation. In the lot D. 5143 were also several gravid 

 females, but only one male with a few eggs in the buccal cavity.
