The same collector has described another similar fish under the 

 name oi Lenclscus thchensis, I.e. pi. 11, which would appear to differ 

 from L. niloticus in having a deeper body, and nine or ten scales in 

 a transverse line. He found it also at Thebes. 



Leuciscus bibie, Be Joannis, 1. c. pi. 4, is another species from the 

 Nile, which has not been rediscovered since it was first described. 

 It is represented with the dorsal placed opposite to the anal fin, which
