of Phoxinus and in the outgroups. the anterior branch is much shorter than the posterior 

 one (TS 207[0]). 



One to three procurrent rays, and seven to eight dorsal rays are present in the species of 

 Phoxinus. Intraspecific variation of the number of rays is present in the genus: see "Species 

 Account'* for discussion on the variation of fin rays for each species. 



Anal fin 



Eight pterygiophores of the anal fin are present in all Phoxinus species: they are similar 

 in shape to dorsal pterygiophores. Each pterygiophore consists of proximal, medial and 

 distal parts. The second to the eighth pterygiophores are similar to each other (though the 

 size decreases posteriorly), not forked, without variation among species of Phoxinus. 

 However, the proximal part of the first pterygiophore is forked in P. oreas and P. tennes- 

 seensis (TS 208[ 1 ]: Fig.91B-C): it is unforked in other species of Phoxinus and in the out- 

 groups (TS 208[0]; Fig.91A).
