56 ACANTHOPTERYGII. 



Genus, 11 — Apogon, Laccp. 



Amia, Gronovius : Apogonichtlvys, Bleeker: Monoprion, Poey : Mionorus, Krefft : Archamia, Lepidamia, 

 and Glossamia, Gill. 



Branchiostegals seven : pseudobranchim present, usually well developed. Operele not spinate. Preopercle with 

 a double edge, either or both of which may be serrated, crenulated, or entire. Teeth- villiform in the jaws, vomer, and 

 palatines, without canines: tongue smooth. Two separate dorsal fins, the first with six or seven spines: the anal with 

 two. Lateral-line distinct and entire. Scales ctenoid, as a rule large and deciduous, but occasionally they are rather 

 small. Coical appendages when present few. 



Geographical distribution. — Froin the Red Sea and East coast of Africa, through the seas of India and 

 Malay Archipelago to Australia, and even beyond. These small fishes are marine, and are numerous in sheltered 

 spots as inside harbours, and some have been captured at the mouth or even a short distance up tidal rivers and 

 backwaters. In the Indian region they are most numerous off the Sind and Bombay coasts, and Andaman 

 islands. 



Uses. — Although small, they are eaten fresh, dried, or salted, by the natives of India. 



The fishes of this Genus, after having been primarily divided in accordance with the number of spines in 

 the first dorsal fin, have undergone various subdivisions, the most popular of which seems to be as regards their 

 colours. The longitudinally or transversely banded ones, those which possess or are deficient in the caudal 

 blotch, have been separated on several plans, and although such may possess advantages they appear to be 

 counterbalanced by marks sometimes disappearing or perhaps never having existed in the specimen. Conse- 

 quently colour will still be omitted from indicating the position of any species, and the number of spines, rays, 

 and scales employed for this purpose. It seems also questionable whether any considerable value can be placed 

 upon the serrations about the bones of the head, especially of the orbits, as such ajspear to be more distinct in some 

 specimens than in others, and may vary with age.
