This species also approaches very nigh to acntirostris ; hut the 

 eye is not wholly over the corner of the mouth. In the compara- 

 tive dimensions of parts there is also some discrepancy. The 

 largest of five specimens measured as follows : — Total length, 17*32 

 in. Length of tail, 105 in. To the comer of the mouth, 051 in. 

 To the pectoral, 197 in. To the dorsal, 5'20 in. Length of pec- 

 toral, 003 in. 



According to M. Guichenot, this species, which varies much, 

 abounds in the fresh waters of Calle, in Algeria.
