16. Naseus {1 Keris) sp. Suvadiva, 37/ 



D. VI, 29; A. ii, 30. 



A single specimen, 37 mm. in total length, closely resembles Keris amhoinensis, Blkr., 

 but differs in having the first dorsal spine longer than the others. Probably, like Keris am- 

 hoinensis. it is the young form of a species of Naseus.

19. Percophis sp. 



D. VII or VIII, 30—35 ; A. 30—35 ; Sc. 52. 



A single badly preserved specimen, 35 mm. in total length, undoubtedly belongs to this 

 genus, which has not before been known to occur in the Indian Ocean, only one species, 

 Percophis hrasilianus, from the coast of Brazil, having been described. 



Depth of body 12 times in the total length, length of head four times. A longitudinal 

 band along the middle of the side. The shape and proportions of the body are exactly the 

 same as in Percophis brasilianus, which has, however, much smaller scales.
