SECOND PART. ABDOMINAL FISHES. 



Having complete gills, witli a gill cover and a 

 branchial membrane. Lower or ventral fins situated 

 on the belly or abdomen, behind the pectoral or 

 lateral fins. 



X. Genus. Goldshad. Pomolobus. Pomolobe. 



Body nearly cylindrical, elongate, scaly. Vent 

 posterior. Abdomen carinated and serrated from 

 the head to the vent ; but without plaits or broad 

 scales. Head scaleless, opercule lobed, with a 

 rounded shield above. Jaws without teeth, upper 

 truncate extensible, lower horizontal and fixed. Ab- 

 dominal fins with nine rays and without lateral 

 appendage : dorsal fin opposite. 



Out of eight species of fishes, similar to the Her- 

 rings and Shads, which have already been observed 

 in the Ohio ; after an attentive study, I have ascer- 

 tained that not a single one is a real Herring, nor 

 belongs to the genus Clupea, and I have been com- 

 pelled to form four new genera with them ; which 

 afford striking characters. The present one differs 

 from the real ge- [ jp] nus Clupea by the lobed and 

 shielded opercule, the curious [II. 171] mouth, the 

 bodily shape, and the want of lateral appendage. It 

 belongs of course, with the four following, to the 

 family of Clupides. The name means lobed oper- 

 cule. 



26th Species. Ohio Goldshad. Pomolobus. chry- 

 sochloris. Pomolobe dore.
