Red Sea, Mozambique, India, East Indies, China. This species 

 greatly resembles Abudefduf saxatiUs and Abudefduf septem- 

 fasckitus^ though closer to the latter. It differs from the latter chiefly 

 in the narrower dark vertical bands and their slightly different dis- 

 position. Our examples usually show a dark basal caudal blotch, 

 possibly due to preservation? 



Chaetodon ahvdafur hanni Forskal is apparently the earliest 

 name applied. It is, however, somewhat doubtful and not clearly 

 diagnosed. The imperfect items are as follows : 



Rostrum obtusum ; denies rigidi ; molares obtusi plurium. serierum; fasciae 

 5 ; alternae latiores ; radii D. 3, 4, 5, inermes, longiores.
