and Dr. Russell, who made his description from life, says, that the cari- 

 nated belly is " serrated with small fibres," probably broken off or over- 

 looked in Cuvier's specimen. I cannot possibly believe, also, that Lace- 

 pede's Esoce chirocentre is of the same species, or even the same sub-genus, 

 as Russell's. 



* Cuvier mentions two. Dr. Russell four. 



•f- Cuvier says that the belly is sharp or carinated [le ventre franchant) ; 

 whereas Le Sueur, the original definer of the genus, and whom he quotes 

 as his authority, expressly remarks that " they are easily distinguished 

 from the Clupecs by the absence of the carinated abdomen;" and again: "Body 

 as in the genus C/wpert, but without carinated abdomen." See Reg. Anim.
