Madagascar, India, Ceylon, East Indies, Philippines, China, Riu 

 Kiu, Japan, Micronesia, North Australia and Queensland. I have 

 followed Sauvage in placing Lethrinus cinereus with this species, 

 although the coloration is described as quite different by Valen- 

 ciennes, possibly because of age. Sauvage gives a figure of the type 

 of Lethrinus frenatus showing : 



Depth 2%; head 2%o. Snout 2Ko in head; eye 3K, 1% in snout; 

 maxillary reaches % to eye, length 2% in head; teeth conic, posterior 

 more rounded above than below; interorbital less than eye, very low. 

 Scales 45 in lateral line, 6 above, 16 below, predorsal extend forward 

 opposite hind eye edge. D. X, 9, fourth and last spines subequal or 

 3 in head, eighth ray 2%; A. Ill, 8, third spine 3)^, first ray 2%; caudal 

 IKo, little emarginate behind; least depth of caudal peduncle 2%; 

 pectoral 1}^; ventral 1%. 



The coloration of Lethrinus Jrenatus by Valenciennes is as follows, 

 his type 225 mm long: 



Back greenish, belly whitish. Along flanks 18 to 20 longitudinal 

 yellowish-olive lines. Back above lateral line spotted with bluish 

 dots. Head olive. Before eye three bluish or violet oblique lines 

 on suborbitals, one also along front and fifth below edge of orbit. 

 Preopercle Hmb with front border violet. Inside mouth orange. 

 Dorsal mottled orange violet which also extends on border of soft 

 dorsal. Anal reddish. Caudal violet. 



Valenciennes says of Lethrinus cinereus, compared with Lethrinus 

 erythrurus, that its body is more elevated, snout shorter, teeth 

 more rounded. Reddish on back, grayish on flanks, belly, and 

 greater part of cheek. Fins grayish. Caudal with traces of dark 

 transverse bands. Pectoral pale yellowish. Length, 150 mm.
