163. Chaetodon capistratus Linnaeus. 



Common; some specimens with an additional spot correspond to Chsetodon bricei Smith, in which 

 species the lower spot, vertically oblong, is in keeping with the existence of the superior one. Both 

 may be remnants of a vertically barred ancestral type, as in ( '. ocellatus, where the fragments of broken 

 and fading bars are more prone to be irregularly oblong than round. (T. ) 



A very instructive series of specimens was found. One 1.25 inches long shows both spots, the 

 upper bordered with white. Another specimen 1.6 inches long has the upper spot represented by a 



dusky area not edged with pale. One 1.25 inches showed no trai f the upper spot. The largest is 



2.58 inches long.
