I have not seen the Anz. K. K. AK. Wiss. Wien, 1882, but 

 presume that the new species of Cheirodon there proposed are 

 identical with those described in the Flussfische IV. If so nattereri 

 and pidcher are used for the same species. Since piilcher is pre- 

 occupied the name nattereri is to be used. If the two names are 

 not used interchangeably by Steindachner the name steindachneri 

 must be used for pidcher.
