A. howelli Hildebrand (j: 105), known only from Santos and Rio de Janeiro, Brazil, 

 in having fewer anal rays, gill rakers, and vertebrae, longer pectoral and pelvic fins, 

 and a slightly more posteriorly inserted pelvic fin. For details, compare the descriptions 

 of the two species.

Body: depth 17.8-20. 

 Head: length 28-29.3. 

 Snout: length 5.17-5.85. 

 Eye: diameter 5.9—7.0. 

 Postorbital: distance 14.7— 16. 

 Maxillary: length 20.5—23. 

 Mandible : length 18-21. 

 Anal fin: length of base 18.5— 21. 



Pectoral fin: length (without filament) 

 15. 5-16. 6. 



Scales: ca. 39 or 40. 

 Gill rakers: 1 7-19 + 20-23. 

 Fin rays : dorsal 13—15; anal 1 9—23 ; pec- 

 toral 13 or 14. 

 Vertebrae: 39 or 40 (3 specimens). 



Body strongly compressed, its depth 5.0-5.6 in SL. Head 3.4—3.6, its depth 

 slightly exceeding the postorbital length. Snout long, projecting nearly its full length 

 beyond mandible, only a little shorter than eye, 5.0—5.5 in head. Eye small, 4.2—4.8. 

 Postorbital part of head 1.6— 1.8 in head. Maxillary not sharply pointed, its upper 

 margin rounded, reaching nearly to margin of opercle, 1.25— 1.3 in head. Mandible 

 1. 4-1. 5. Cheek narrow, equal to eye and snout, its posterior angle sharp, about 30°. 



Dorsal fin rather high anteriorly, its longest rays reaching nearly to tip of last 

 ray if deflexed, its origin slightly nearer to tip of snout than to base of caudal. Anal 

 with origin nearly under the beginning of the last third of dorsal base, the base 4.8- 

 5.4 in SL. Pelvic reaching much more than halfway to anal, inserted a little nearer 

 to pectoral base than to anal origin. Pectoral with upper ray produced, its filament 

 (often broken) extending to, and possibly beyond, tip of pelvic in perfect specimens, 

 the fin, without filament (second ray), reaching base of pelvic, 1.6— 1.8 in head.
