Scales: ca. j^2~47i often lost from pre- Fin rays: dorsal 17-19; anal 15-18; 



served specimens. pectoral 16 or 17. 



Fenfra/ scutes: 32-34. Vertebrae: 46-47 (3 specimens). 



Body with greatest thickness exceeding half of depth, its greatest depth 4.5—5.5 

 in SL; ventral outline notably more strongly convex than dorsal outline. Caudal 

 PEDUNCLE slender, its depth 3.0—3.75 in head. 



Scales lost in most specimens, apparently not different from those of S. an- 

 chovia; 6 or j rows of scales exposed between tip of pectoral and base of pelvic. Ven- 

 tral SCUTES not strong, 18 or 19 in advance of pelvics and 14 or 15 behind them. 



Figure 98. Sardinella pinnu/a, about 124 mm TL (caudal damaged), 100 mm SL, Bermuda, USNM 21252. 

 Drawn by Ann S. Green. 



Head small, slender, 3.85-4.15 in SL, its depth at vertical from crossgroove at 

 occiput 5.0—6.1 in SL. Snout moderately long, 3.2—3.4 in head. Eye small, its di- 

 ameter definitely shorter than snout, 3.55—4.15 in head. Interorbital 4.7-5.9. Cheek 

 longer than deep. Maxillary rather broadly rounded posteriorly, scarcely reaching 

 vertical from anterior margin of pupil, 2.3-2.6 in head. Mandible projecting mod- 

 erately, its margin within mouth rising rather gradually, without a definite angle. Gill 

 RAKERS long, slender, close-set, difficult to count, those at angle about as long as eye, 

 the serrations on inner edge of rakers minute; the rakers increasing in number with 

 age: about 75 on lower limb of first arch in specimens about 85 mm long, about 90 in 

 those about 100 mm SL (gill rakers removed for counting). Teeth as in S. anchovia. 



Dorsal fin rather high anteriorly, its margin definitely concave, its longest ray 

 generally reaching to or beyond tip of last ray if deflexed, its origin rather nearer to 

 margin of snout than to vertical from base of last anal ray, its distance from margin of 

 snout 2.3-2.4 in SL; the base with a very narrow sheath of scales. Caudal forked; 

 broken in all specimens at hand. Anal fin much lower than dorsal, with a slight lobe 

 anteriorly, its last two enlarged rays nearly as long as the longest ones in anterior lobe 

 of fin, its origin about equidistant between insertion of pelvic and base of caudal, 

 its base 1.55— 1.9 in head. Pelvic fin reaching a little more than a third of the way
