is absent in other species of Phoxinus and in the outgroups (TS 194[0]). The coracoidal 

 end expands in P. cumberlandensis and eos (TS 1 95 [ 1 ] ); whereas it does not expand in 

 other species of Phoxinus or in the outgroups (TS 195[0]). 



Scapula (Fig. 83 A). The scapula bears a large round foramen at its central, and different 

 facets articulating the cleithrum, mosocoracoid, coracoid, and first pectoral fin-ray. No sig- 

 nificant variation is present among the species of Phoxinus. 



Radials (Figs. 83 A, 86, 87A-F). Four radials are present in each pectoral fin in Phoxi- 

 nus. namely the radials 1, 2, 3, and 4 (Figs. 83 A, 87A-F). 



The first radial is the shortest among the four. Two articular facets are present at the la-
