2000. IKIDIO CYANOCEPHALUS (Blocb). 



Head 3^; depth 3^. 1). IX, 12; A. Ill, 12; scales 3-26-9. Body rather 

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

 scales before dorsal fin not crossing the median line; ventral lins 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 baud 

 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 baud becoming faint 

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

 band ujiward and backward from eye to nape, rather conspicuous, uar- 

 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 j)lain greenish, iudigo above. The 

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

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

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

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

 also examined a smaller specimen from 8t. 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.
