FISHES OF THE PHILIPPINE AND ADJACENT SEAS 251 



We give a number of illustrations of the species suitable to show 

 the variation of color-pattern on the head. Unfortunately in a num- 

 ber of cases these designs have faded from the specimens, so that we 

 could not prepare more complete series of figures. In few, if any 

 cases, have we found the designs exactly alike on both sides of the head.
