Description. Proportional dimensions in per cent of standard length, and counts, 

 based on 15 or more specimens from 33 mm SL upward. 



Body: depth 18-20. 

 Head: length 22-26.2. 

 Snout: length 4.15—5.7. 

 Eye: diameter 6.9-8.0. 

 Postorbital: distance 10.5— 14.2. 

 Maxillary: length 1 6.4-1 9.3. 

 Mandible: length 1 5.3-1 7. 



Anal fin: length of base 22—26. 

 Pectoral fin: length 1 5.6-1 7.5. 



Scales: ca. 36—40. 



Gill rakers : 20-23 + 23-26. 



Fin rays: dorsal 14 or 15; anal 21—24; 



pectoral 12 or 13. 

 Vertebrae: 41 or 42 (3 specimens). 



Body strongly compressed, its depth 4.3-5.0 in SL. Head short, 3.8-4.5 in SL, 

 its depth equal to its length without snout. Snout 5.0-6.0 in head, projecting fully 

 half of its length beyond mandible. Eye 2.9-3.6 in head. Postorbital 2.0-2.3 in 

 head. Maxillary rather bluntly pointed, its upper margin somewhat rounded, reaching 

 to, or slightly beyond, joint of mandible, 1.3-1.5 in head. Mandible i. 4-1. 55. Cheek 

 about as long as eye, its posterior angle about 50°. 



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

 equidistant between base of caudal and about middle of eye. Anal low, its origin 

 under or slightly posterior to middle of dorsal base, its base scarcely shorter than head, 

 3.8—4.5 in SL. Pelvic very small, reaching much less than halfway to anal, inserted 

 about equidistant between origin of anal and base of pectoral. Pectoral small, failing 

 to reach ventral by more than half of diameter of eye, 1.4-2.0 in head. Axillary 

 scale of pectoral about 75% of length of fin, 2.4 in head. 



Color. In alcohol, pale silvery. Silvery lateral band distinct, about 0.5-0.66 of width 

 of eye. Back with dark punctulations, arranged in two rows in some specimens, probably 

 faded in others. 



Size. So far as known, this Anchovy reaches a length of only about 75 mm 



(3 in-)- 



Range. It apparently ranges from the Gulf of Venezuela to Rio de Janeiro, Brazil.
