 o£ dorsal. Caudal peduncle as long as deep, or deeper than 

 loii<?. Silvery ; back darker. 



Atlantic coast of U.S.A.

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



1. Brevoortia tyrannus. 



Clupea tyrannus, Latrobe, Trans. Amer. Phil. Soc. v. 1872, p. 77, pi. i. 

 Cliq)anijdu)i aureus, Agassiz, Spix, Pise. Brasil. p. o2, pi. xxi. (1828). 

 Clupea menhaden (Mitchill, l8loj, Guutli. Cat. ilsli. vii. p. 43b (1878).

p. •i(Jt>. 



Hrevoortia patronus, Goode, t. c. p. 2G, pi. v. 



Depth of body 2^ to '6\ in the length, length of head 2i to 

 31. About 70 gill-iakers (in the adult) on ceratobranchial 

 oi first arch. About 50 scales in a longitudinal and 25 in a 

 tiansverse series ; in adults scales very deep, two often 

 nieetin;i,- across one of the intermediate longitudinal series, 

 thus increasing the number of transverse rows ; ventral scutes 

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

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



Nova Scotia to Gulf of Mexico and Brazil. 



Several examjdes 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 Xurth American ; tlie di.'stri- 

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

 to be made out.
