 Plate VIII. Fig 2. 



Height of body two and a half times in the total length. Head 

 four times in the same. Diameter of orbit much less than the 

 distance between the eyes. Muzzle distant from the eye much more 

 than two diameters of the orbit. Teeth rather small. Scales on the 

 lateral line 47. Pectoral fin elongate. Caudal emarginate, wide- 

 spread. Colour greenish olive, paler beneath, with an almost obso- 

 lete dark mark beneath the lateral line near the pectoral tin, and 

 several very indistinct brown bands from the back to the belly, 

 becoming more conspicuous towards the tail. The ventral, anal 

 and dorsal fins brownish ; the soft dorsal spotted. 



One specimen was caught at the Percy Islands. 



It is of an unusually deep compressed form, being four inches 

 two lines in height to a total length of ten inches four lines. 



40. — Lethrinus Papuensis. 

 Plate VIII. Fig. 1. 



Height of body three and one-thrrd times in the total length, 

 head four times in the same. Diameter of orbit nearly one-third 

 of the length of the head, and rather less than the space between 

 the eyes. Snout rather narrow. Molar teeth distinct. Scales on 

 lateral line, 48. Spines of dorsal fin feeble. Caudal fin emarginate. 

 Colour dark olive on the back, becoming yellowish towards the 

 belly, with a large obscure black spot below the lateral line, about 

 the middle of the body. 



One specimen of this very distinct species was got at Hall 

 Sound, New Guinea. It seems to have most resemblance to 

 Lethrinus Banhamemis, Guntli. Jour. Mus. Godeff., Heft. 7, pi. 47.
