FISHES OF THE PHILIPPINE SEAS AND ADJACENT WATERS 63 



Seychelles. The types, obtained by Dussumier, were nearly 305 

 mm long. 



LETHBINUS ARGENTEUS Valenciennes 



Lethrinus argerdeus Valenciennes, Hist. Nat. Poiss., vol. 6, p. 303, 1830 (type 

 locality: Seychelles). — Sauvage, Hist. Nat. Madagascar, Poiss., p. 199, pi. 

 23, figs. 2a-b, 1891 (type). 



Depth 2%] head 3, upper front profile straight. Snout 1% in head 

 from snout tip; eye 3%, 2 in snout; maxillary reaches % to eye, expan- 

 sion 1% in eye, length 2% in head from snout tip; teeth conic, small, 

 more rounded in upper jaw; interorbital low, greater than eye. 



Scales 55 in lateral line to caudal base and 6 more nontubular out 

 over latter; 6 above, 17 below, predorsal scales forward opposite hind 

 eye edge. 



D. X, 9 (XI, 8 on figure), second spine 2% in total head length, 

 fourth ray 2Ko; A. Ill, 8, second spine 3%, first ray 2%; caudal 1%, 

 deeply emarginate; least depth of caudal peduncle 3)8; pectoral IK; 

 ventral 1%. 



Silvery, with nacry reflection; all fins rosy, except pectoral which 

 is yellowdsh. (Sauvage.) 



Valenciennes gives 175 mm as the length of his type. Sauvage says 

 it is near Lethrinus Jasciaius, but the latter differs in its convex pro- 

 file. It suggests Lethrinus ramak, except the second dorsal spine is 

 shown as the longest dorsal spine in Sauvage's figure. In this respect 

 it surely approaches close to Lethrinus nematacanthus. 



Genus NEOLETHRINUS Castelnau 



Neolethrinus Castelnau, Res. Fish. Austral. (Off. Rec. Philadelphia Exhib. 

 Victoria), p. 11, 1875. (Type, Neolethrinus similis Castelnau, orthotypic.) 



Like Lethrinus except whole palate and all inside of mouth with 

 small molar teeth. 



One species in Queensland. 



NEOLETHRINUS SIMIUS Castelnau

 telnau).
