front rays elongate, and graduated down from first branched. Anal 

 origin about opposite first fourth in dorsal length, front rays elongate 

 and graduated down from first branched rays, fin low behind. Caudal 

 deeply forked, lobes pointed and nearly equal. Pectoral pointed, 

 reaches ventral. Latter inserted little nearer pectoral than anal, 

 half way to vent, which close before anal or well behind dorsal origin. 



Color in alcohol, when fresh, upper surface of back very pale 

 olive, inclining to pale yellowish. Head, sides and lower surface 

 bright silvery-white, and apparently no distinct lateral band length- 

 wise. Iris whitish, also fins. Dorsal and caudal very slightly tinted

 its entire extent.

Type, No. 45,079, A. N. S. P. Port-of-Spain, Trinidad, British 

 West Indies. February-March, 19L5. Richard M. Abbott. 



Only the above example was obtained. I first thought this must 

 be Stole phorus surinamensis Bleeker,^ a species formerly wrongly 

 identified by most writers with Engraulis clupeoides Swainson. It 

 differs, however, from Bleeker's species in several respects, and 

 therefore for the present it may be regarded as distinct. Bleeker's 

 examples were 96 mm. long, and are described with the scales as 

 35, the fins yellowish and the caudal broadly edged brownish behind. 

 Dr. Eigenmann gives ^^ 35 gill-rakers on the lower arch of A. suri- 

 namensis. 



(Named for Mr. Richard M. Abbott, who collected the type.)
