maxillary and suborbitals naked. Scales with 7 to 18 basal radiating 

 striae; 44 to 128 apical denticles, with 1 to 6 transverse series of basal 

 elements; circuli moderate. 



D. VII-I, 9, i, third spine 2 to 2}/g in total head length, first ray 

 1% to \%; A. II, 8, i, second spine 2% to 2%, first ray 1% to 1%; 

 caudal lXo to 1 3^s, slightly emarginate behind, with rounded lobes; 

 least depth of caudal peduncle 2% to 3; pectoral 1% to 13^; ventral 

 IK to 1%. 



Back brown, below paler to whitish, with silvery to brassy tints on 

 opercles, lower side of head and abdomen. Iris whitish or grayish. 

 Broad dusky brown vertical band, four scales wide at caudal base, 

 extends slightly along upper and lower basal edges of caudal. Fins

 spicuous subbasal longitudinal brown line. Spinous dorsal dusky 

 gray. Ventral with front edge grayish. 



Red Sea, Mozambique, Natal, Ceylon, India, East Indies, Philip-

We do not accept Barnard's contention, 6 in which he says: " Ostor- 

 Jiinchus fleurieu Lac6p. and Dipterodon liexacanihus Lacep. can not be 

 included in the synonymy of this species, as the descriptions of the 

 dentition are not those of an Apogon at all." 



Both descriptions and figures are truly vague and crude, though 

 seem to us unmistakeably those of the present species. Of Ostorhin- 

 chus fleurieu Lacepede says the snout, comprising the two bony jaws 

 is well produced, resembling those of the scaroids, diodons, ovoides, 

 tetrodons, tortoises, same as the beak of the parrakeets. For Dipter- 

 odon, which includes D. plumieri and D. notatus besides the genotype 

 D. hexacanthus, the loose diagnosis is inaccurate, as the dentition is 

 said to have the incisors compressed, pointed, and equidistant. Both 

 the figures of Ostorhinchus fleurieu and Dipterodon hexacanthus agree 

 in the dark transverse band across the caudal peduncle at or near the 

 caudal base. The large teeth shown in the figure of the latter we 

 think an error in engraving.
