 which signifies, that there are 4'/^ rows of scales between the 

 dorsal fin and the lateral line, one in the lateral line itself 

 and one between it and the ventral fin. 



In the Fin fonnulac the spines and the simple, non-branched 

 rays are generally indicated by a figure, separated by a point 

 from that of the number of the branched rays. 



The last soft ray of the dorsal and anal, in case it is cleft 

 to the base and therefore counted as two by some authors 

 (Bleeker e. g.), is reckoned as one, being supported by a 

 single pterygophore. 



The Gilliiievihranes may be totally free from each other and 

 from the isthmus; they may be united, but still remain free 

 from the isthmus ; or they may be connected with the isthmus 

 and with each other. When in the last case the posterior 

 border of the united gillmembranes is not quite adnata to the 

 isthmus, there remains a free posterior margin, running as a 

 fold over the isthmus from one gillopening to the other. 



We follow the law of priority and use the oldest name 

 which can with certainty be made out by the description, 

 belonging to a certain species. Its author is quoted as the 

 author of the species and his paper is quoted in the first place, 

 when there is no stringent reason to do otherwise. 



Mention is further made of all synonyms; besides, we have 

 quoted those papers, which contain a description of the species. 

 If it is a widely spread one, only those papers are quoted, 

 which contain a description of or give some informations — 

 others than those regarding locality only — about Indo-Aus- 

 tralian specimens of that species. 



According to the international rules of nomenclature we 

 have neglected the generic names, as e.g. those of SWAINSUN, 

 which are not accompanied by a description. 



We have recorded under: "•nomina indigena" those native 

 names, which seemed to us to be trustworthy. We are of
