 Tenualosa Fowler, Proc. Acad. Nat. Sci. Philadelphia, vol. 85, p. 246, 1934. 



(Type, Alosa reevesH Richardson, orthotypic.) 



Body compressed. Belly keeled, with scutes. Maxillary with 

 rather wide supplemental bone. Premaxillaries meet at acute angle. 

 No teeth. Gill rakers very numerous, long, slender. Pseudobranchiae 

 present. Branchiostegals 5. Scales adherent. No enlarged scales at 

 caudal base. Anal long. Ventrals below dorsal. 



Coasts and rivers of East Africa from Natal to China. Young 

 examples have deeper bodies and smaller heads than the adults, the 

 latter largely due to the size of the opercle.
