FISHES OF THE PHILIPPINE ISLANDS AND ADJACENT SEAS 147 



dorsals usually joined basally, usually the presence of three anal 

 spines and their silvery coloration. 



We admit the genera Tetracentrum Macleay and Hamiltonia Swain- 

 son, CTianda Buchanan-Hamilton, Parcunbassis Bleeker and Ambassis 

 Cuvier, as defined by Fowler in 1905. As Chanda is the oldest generic 

 name, Chandidae follows as the accepted family name. 



ANALYSIS OF THE GENERA

 or somewhat caninelike; scales usually quite small Parambassis 



a 2 . Teeth uniformly small, none prominently enlarged, usually in villiform 

 bands; scales large Ambassis
