The diameter of the eye is one third of the length of the head, and much less than that of the postorbital portion. Preeorbital strongly serrated. Lateral line continuous. The second dorsal spine is rather shorter than the third, and contained four times and one fourth in the total length (without caudal). The third anal spine longer tnan the second, but considerably shorter than the second of the ciorsai Body with a silvery longitudinal band; the membrane between the second and third dorsal spines and a band along each caudal lobe blackish. „ ,, -, 1 ,_. One specimen (no. 256), 2f inches long, from the Godeffroy Museum ; it is from Rarotonga (Cook's Islands). _ This species is undoubtedly distinct from our specimens from Celebes and the Seychelles named A. uroteenia, and easily distinguished by the difference in the size of the eye. But we may hesitate to affirm its distinctness from the specimens from Amboyna and Wahai, described by Bleeker under the same name. He states that the diameter of the eye is two fifths or one third oi the length of the head (Nat. Tyds. Ned. Ind. 1852, p. 257), an amount of variation as I have never observed it in Ambassis. APOGON SAVAYENSIS. D. 7||. A. f. L. lat. 26. The height of the body is nearly equal to the length of the head, and two fifths of the total (without caudal). The width of the interorbital space is two thirds of the diameter of the eye, which is two fifths of the length of the head, and equal to that of the postorbital portion. Only the posterior edge of the praeoperculum is finely denticulated. Dorsal spines feeble: the first minute, the third the longest and as long as the eye. Caudal fin subtruncated. Ventral fins extending to the vent. Bronze-coloured; an oblique blackish band from the eye to the angle of the preeoperculum. A blackish cross band on the back of the tail, about three scales broad, and not extending downwards beyond the lateral line. One specimen (no. 78) from Savay (Samoa Islands), 2J- inches long, has been obtained from the Godeffroy Museum. ' Two other examples, 3| inches long, have been sent from Manado bv Dr Meyer. 3 This species appears to be closely allied to A. bandanensis (Blkr ^1 • but our specimens have no bands on the body, and Bleeker d . mention the oblique band on the cheek, which, however •°eS distinct in the specimen from Savay than in those from Celeb m ° re PRIACANTHUS MEYERI.
