9. CH^TODIPTERUS. 



Ghcetodipterus (iv., 503; Glicetodon plumieri^ Gmeliu.) is correctly dis- 

 tinguished from Chcetodon, by the separation of the dorsal fins. Its type 

 is identical with Zeusfaher Broussonet. The name Chcetodipterus must 

 therefore supersede ParepMppus Gill, as Bleeker has already shown. 



10. POMADASYS. 



Pomadasys (iv. 515) is based on Scimia argentea Forskai, which is a 

 species of Cuvier's genus Pristipoma, according to Giinther and Cuvier. 



The generic description is not altogether correct, but is copied from 

 the specific description of Forskiil. The name Pomadasys must there- 

 fore take the place of Pnstipoma, a change already made by Cantor and 

 Bleeker. 



11. clupa:n^odox. 



The genus Clupanodon was proposed by La Cepede (Hist. Nat. Poiss., 

 V. 468, 1803) for those species of Glupea which had no teeth in the 

 jaws, and with the following definition : 



" Plus detrois rayons a la membrane des branchies, le ventre carene; 

 la carene du ventre dentelee on tres-aigus; la nageoire de I'anus separee 

 de celle de la queue ; une seule nageoire sur le dos ; point de dents 

 aux machoires." 



Six species are referred by La Cepede to this genus, viz : 



thrissa (L.). {Opisthonema Gill.) 



nasicaliSkC. {nasus Bloch). {Dorosonia Raf.) 



pilchardm L. {Sardinia Poey.) 



sinensis L. {Glupeonia C. & V.) 



africanus Bloch. {Pellona, C. & V.) 



jussieu liac. [Glupeonia Q.&.Y.) 



One of these, Pellona africana^ does not conform to the definition and 

 should be excluded. All the others (except Dorosoma nasus) are very 

 closely related, and are probably all representatives of sections of the 

 genus Glupea rather than of distinct genera. The name of Glupanodon 

 is prior to all of these and must take the place of one of them. So far 

 as we know, it has never been formally restricted. It seems to us best 

 to consider G.jussieui as the type of Glupanodon, and to substitute 

 Clupanodon for Glupeonia. 



12. GYMNOMUE^NA. 



The genus Gymnomurcena La O^pede (Hist. ITat. Poiss., v. 618, 1803), 

 was defined as follows : 



" Point de nageoires pectorales ; une ouverture branchiale sur chaque 

 c6t6 du poisson ; le corps et la queue presque cylindriques ; point de 

 nageoire du dos, ni de nngeoire de I'anus; ou ces deux nageoires si
