Figure 99. Sardinella anchovia, about 120 mm TL, 95 mm SL, Woods Hole, Massachusetts, USNM 90233. 

 Drawn by Ann S. Green. 



Body rather strongly compressed, its greatest thickness generally less than half of 

 its depth, its greatest depth 3.7—4.75 in SL; ventral outline notably more strongly 

 convex than dorsal outline. Caudal peduncle slender, moderately compressed, its 

 depth 2.5—3.6 in head. 



Scales moderately adherent, those from middle of side below anterior rays of 

 dorsal scarcely deeper than long, with 3 or 4 more or less complete vertical grooves, 

 the margin of these scales scarcely indented but scales on back in front of dorsal fin 

 definitely indented; 6—8 rows of scales exposed between tip of pectoral and base of 

 pelvic fin. The pair of modified scales at nape small, shorter than eye. Ventral 

 SCUTES small, 18 or 19 in front of pelvic fins and 14 or 15 behind them. 



Head 3.65—4.35 in SL, its depth at vertical from crossgroove at occiput 4.95—5.1. 

 Snout 3.0—3.9 in head, its margin without a median notch. Eye shorter than snout, 

 3.4—4.5 in head. Interorbital bone (over middle of eye) 4.3—6.0. Cheek longer than 

 deep. Maxillary rounded posteriorly, reaching to or a little beyond vertical from 

 anterior margin of pupil, 2.3—2.7 in head. Mandible projecting only slightly, its 

 margin without mouth rising rather gradually without a definite angle. Gill rakers 

 long, slender, close-set, those at angle about as long as eye, the serrations on inner edge 

 minute, the rakers increasing in number with age, difficult to count; about 55—60 on
