Figure 59. Cetengraulis edentulus, 120 mm TL, 100 mm SL, from Havana, Cuba, USNM 35159. Drawn 

 by Louella E. Cable. 



Dorsal fin with the longest rays failing to reach tip of last ray if deflexed, its 

 origin generally about equidistant between anterior margin of eye and caudal base. 

 Anal with origin usually under last fourth of dorsal base, its base 4.3—4.6 in SL. 

 Pelvic inserted nearer to anal origin than to pectoral base, generally reaching fully 

 halfway to origin of anal. Pectoral usually failing to reach base of pelvic, 1.9-2.3 

 in head. Axillary scale of pectoral broad, with a somewhat thickened ventral edge, 

 3.25—3.7 in head. 



Color. In alcohol, bluish gray above; lower 75''/o of side silvery. Small specimens 

 with a silvery lateral band, becoming wider and less distinct with age, generally dis- 

 appearing at a length of about 100 mm. 



Size. Specimens as much as 165 mm {6.(i in.) TL have been reported.
