%Tnther describes Bennett's type as blue, head black, chest and 

 rmg encoding lower part of mouth white, caudal with 2 black cres- 

 cents of which one across base and the other marginal ana both united 

 by upper and lower edges of fin. There is little doubt but that it 

 applies to AcantTcurus celehicus Bleeker which has a similar pattern 

 of coloration. As Giinther thought Acantliurus Juscus Steindachner 

 is another synonym, evidently the adult.
