2000. IRIDIO CYANOCEPHALUS (Blocb). 



Head 3; depth 3. D. IX, 12; A. Ill, 12; scales 3-26-9. Body rather 

 robust, profile rather steep, snout moderately pointed, the 4 to 6 rows of 

 scales before dorsal fin not crossing the median line ; ventral fins with the 

 outer rays produced, more than twice the length of the inner. Deep 

 olive green on head and back, the head bluer, then a broad lateral band 

 of deep indigo extending from eye to tip of caudal, below this light clear 

 green, then a darker bluish green; clear blue on lower jaw below and 

 clear greenish blue on lower part of cheek; lateral band becoming faint 

 on head; a dark streak along profile from snout to nape; a dark bluish 

 band upward and backward from eye to nape, rather conspicuous, nar- 

 rowed posteriorly; dorsal indigo, edged with sky blue; caudal green, 

 indigo in center, yellowish at tip; anal indigo, then dull orange, then 

 sky blue; ventrals green; pectorals plain greenish, indigo above. The 

 Cuban species called internasalis is not different from the Brazilian dimi- 

 diatus, the alleged differences in color being due to defects in descriptions. 

 A specimen before us from Bahia shows the band from eye to nape very 

 distinctly. It is broader behind and edged with darker blue. We have 

 also examined a smaller specimen from St. Lucia. Here described from 2 

 male specimens from Havana, each about 15 inches in length. West 

 Indies, south to Brazil, generally common, reaching a length of 15 inches.
