eigenmann: pimelodella and typhlobagrus 



241 



Boulenger was the first to recognize that Cope's specimens belonged to a 

 species distinct from P. lateristriga. There is little doubt but that P. copei is a 

 synonym of P. buckleiji. The P. buckleyi of E. & E. is a distinct species called 

 P. Eigenmanni by Boulenger, and P. Eigenmanniorum by Ribeiro.
