Fig.47: Epioccipital of Phoxi- 

 nus (a: dorsal view; b: ventral 

 view). A: P. cumberlandensis 

 (KU 18934; 52.0 mm SL); B: 

 P. phoxinus (CNUC uncat., 

 76.0 mm TL); C: P. neogaeus 

 (KU 8521, 53 mm TL). Scale 

 bars = 1 mm. 



The epioccipital bears two or three concavities on its ventral aspect. The concavities are 

 separated one another by ridge-like structures. In P. neogaeus, the anterior concavity bears 

 another deeper "subconcavity" at its anterior portion (TS 74[1]; Fig.47C). The "subcon- 

 cavity" is absent in other species of Phoxinus (TS 74[0]).
