FISHES OF THE PHILIPPINE SEAS AND ADJACENT WATERS 251 



bright silvery white. Snout edge and upper lip dusky. Spinous 

 dorsal blackish on membranes terminally. Row of dark spots on 

 soft dorsal, one on each membrane below middle and concealed by 

 basal scaly sheaths. 



Red Sea, Arabia, Portuguese East Africa, Natal, Mauritius, Mada- 

 gascar, India, Ceylon, Pinang, East Indies, Philippines, Indo-China, 

 China, Riu Kiu, Queensland, Melanesia. Several nominal species 

 are apparently synonymous with the present one. Gerres philippinus 

 Giinther seems to be known chiefly from its original description. 

 I think this suggests Gerres Jllamentosus, especially as its second dorsal 

 spine is described as elongate or % the body depth. This character is 

 shared by no other Indo-Pacific species. Its characters in brief are: 



Depth 2%; head 2%. Eye 3 in head, more than snout, equals 

 interorbital. Scales 48 in lateral line; 6 above, 12 below; dorsal scaly 

 sheath very high. D. IX, 10; A. Ill, 7, second spine much stronger 

 but scarcely shorter than third, not quite half of head. Pectoral 

 reaches second anal spine. Silvery. Each dorsal ray and hind 

 spines with blackish spot near base. Length, 88 mm. 



The imperfectly described and deep bodied Gerres cheverti may be 

 another synonym. It differs, however, in that the figure shows 8 

 scales above the lateral line and 12 below to the anal origin. 



Depth 2K; head 3%. Eye 2% in head, apparently longer than snout 

 (figure shown with mouth extended). Lateral line 40 (on figure about 

 45 rows to caudal base). D. IX, 10 (11 rays on figure), second spine 

 half body depth; A. Ill, 7 (8 rays on figure), second and third spines 

 subequally large, though second more robust; on figure pectoral shown 

 long as head. Bright silvery. Dorsal pale, tipped black. Anal and 

 ventral deep yellow. Length, 100 mm.
