of the Genera Poniolobus, Bievoortin, (tr. 301 



Dorsal 16-18. Anal 18-22. Pelvics below anterior lialf 

 of dorsal. Caudal peduncle as long as deep, or deeper than 

 long. Silvery ; back darker. 



Atlantic coast of U.S.A. 



Seven specimens, 220 to 260 mm. in total length. 



4. BllEVOORTIA, Gill, 1801. 



Proc. Ac. Pliiladelphia, p. 37; Jord. & Everm. Bull. U.S. Nat. Mas. 

 xlvii. 1896, p. 433. 



This genus is distinguished from Alosa by the pectinated 

 scales. The gill-rakers are very numerous, long and slender.

 Brevoortia patronus, Goode, t. c. p. 26, pi. v. 



Depth of body 2^ to 3^ in the length, length of head 2| to 

 3^. About 70 gill-rakers (in the adult) on ceratobranchial 

 ot first arch. About 60 scales in a longitudinal and 25 in a 

 transverse series ; in adults scales very deep, two often 

 meeting across one of the intermediate longitudinal series, 

 thus increasing the number of transverse rows ; ventral scutes 

 18-20 + 11-12. Dor.sal 18-21. Anal 19-24. Pelvics 

 below or in advance of anterior rays of dorsal. Vertebraj 48. 



Nova Scotia to Gulf of Mexico and Brazil. 



Several exani[)les up to 350 mm. in total length ; one of 

 these, from Alabama, and therefore B. patronus, is exactly 

 similar to the specimen 8 inches long, from Woods Hole, 

 figured by Goode. Giinther''s example named Clupea aurea 

 is without locality, and may be North American ; tlie distri- 

 bution of this species on the coast of South America has yet 

 to be made out.
