Range. — Both coasts of tropical America ; West Indies ; Revil-

Very similar to Hawaiian specimens recorded by Jenkins ^ and by 

 Jordan and Evermann ^ as Abudefduf abdominalis (C. & V.) Differs 

 from this species in having the band on the caudal peduncle more dis- 

 tinct and in lacking the spots on the base of the soft dorsal and the 

 anal opposite the ends of this band. 



We have specimens from Charles Island and from Tagus Cove, 

 Turtle Point, Elizabeth Bay and Iguana Cove, Albemarle. 



A small specimen 16 mm. long has the soft dorsal, soft anal, caudal 

 and pectoral fins very pale, strongly contrasting with the other parts. 

 Specimens larger than this, up to 25 mm., have these fins pale but 

 darker than in the smaller ones. The vertical bars are present on speci- 

 mens as small as 16 mm. in length. Specimens 10 mm. long, how- 

 ever, have no stripes at all.
