 LETHRINUS OUVACEUS Valenciennes 



Leihrinus olivaceus Valenciennes, Hist. Nat. Poiss., vol. 6, p. 295, 1830 (type 

 locality: Anjer, Sunda Straits, Java). — Peters, Arch. Naturg., 1855, p. 243 

 (Mozambique). — Sauvage, Hist. Nat. Madagascar, Poiss., p. 198, pi. 23, 

 figs. 3, a-b, 1891 (Madagascar; types of Leihrinus olivaceus and Lethrinus 

 waigiensis; Seychelles). 



Lethrinus waigiensis Valenciennes, Hist. Nat. Poiss., vol. 6, p. 297, 1830 (type 

 locality: Waigiu; New Guinea). 



Depth 3; head 3, upper profile very sKghtly arched. Snout 2 in 

 suborbital depth to maxillarj^ expansion; maxillary reaches % to eye, 

 length 2% in head; canines weak and teeth pointed; interorbital low. 



Scales 52 in lateral line (57 on figure); 6 above, 13 below, predorsal 

 forward opposite hind eye edge; apparently small postocular scale. 



D. X, 9, fourth spine 2^ in head, second ray 2)^; A. Ill, 8, third 

 spine 4, second ray 2%; caudal 1%, deeply forked; least depth of caudal 

 peduncle 3; pectoral 1%; ventral 1%. (Sauvage.) 



Mozambique, Madagascar, Seychelles, East Indies. Valenciennes 

 gives the following coloration: Olive-green on back, head and tail 

 below more yellow; lips reddish, also base of preopercle. Cheek 

 rayed by 5 oblique green bands, of which 3 upper from eye to lips 

 and other 2 interrupted and undulate. Spinous dorsal yellowish, 

 edged orange and spots of flame gold and large dots of olive at base 

 of each spine; membranes of soft dorsal golden, also pectoral and 

 caudal rays yellow. Anal and ventral yellow. Length, 200 mm. 



Sauvage contends the present species is different from Lethrinus 

 miniatus. Lethrinus waigiensis and Lethrinus olivaceus were identified 

 with Lethrinus miniatus by Bleeker, though Sauvage, after an exami- 

 nation of the types, found they differed chiefly in smaller scales and 

 less extended snout. Lethrinus waigiensis was based on an example 

 but 175 mm long and described as brown on the back, silvery belov/. 

 Snout blackish and body clouded with large blackish marblings. 

 Some traces of brown bands on jaws. 



LETHRINUS MICRODON Valenciennes 



Lethrinus microdon Valenciennes, Hist. Nat. Poiss., vol. 6, p. 295, 1830 (type 

 locality: Bouro). — Sauvage, Hist. Nat. Madagascar, Poiss., p. 198, pi. 25, 

 figs. 1-a, 1891 (type). 



Depth d%; head 3, upper profile very slightly convex. Snout 2% in 

 head from snout tip; eye 3K, IJa in snout, equals suborbital depth; 

 mandible shghtly protrudes; maxillary reaches % to eye, length 2% in 

 head from snout tip; canines weak (shown as moderate on figure), 

 hind teeth small and pointed; interorbital low, less than eye. 



Scales 48 in lateral fine (44 on figure); 3 above, 12 below, predorsal 

 shown forward only opposite hind preopercle ridge; no postocular 

 scale.
