FAMILY SCARIDAE — SCHULTZ 247 



alive) caudal area in which is a roundish dark blotch at base of caudal 

 fin; lips pale, yellowish to pink when alive. When it has attained the 

 greenish stage of adult life the characteristic green and pinkish streaks 

 or bands around the mouth are useful along with the broad green band 

 distally on anal fin and narrow band distally on dorsal, as follows: 

 Blue-green band above pale (pink when alive) edge of upper lip that 

 extends to the eye; the broad green band on lower jaw just behind 

 pale (pink when alive) edge of lower lip extends to eye, joining the 

 green band from upper lip at corner of mouth, these green bands more 

 or less fade posterioventrally without a distinct edge. 



Ecology. — This parrotfish was the most abundant species in the 

 intertidal zone of the reef and occurred at depths down to 45 feet, and 

 probably deeper, but that zone was not investigated thoroughly. 

 Wherever algae and coral grew, this species was found. The intestinal 

 tract was filled with algal-coral debris.
