This species is extremely similar to A. lucklus, with which it 

 agrees, except in having generally fewer scales and anal rays, also 

 a smaller number of vertebrae. It may be regarded as the southern, 

 less developed form of Alb. luddus.

Alburnus fraecliia of Heckel is regarded and described by Prof. 

 Canestrini as Alburnus alborella, var. lateristriga, 1. c. iii. p. 103, and 

 iv. p. 87. It is distinguished by a rather indistinct greyish band 

 along the side. Specimens have been obtained from Treviso, Bologna, 

 and Modena. Prof. Canestrini considers it possible that it is a hybrid 

 between Alburnus alborella &m\'Leucos aula. Leuciscus albidus, Costa, 

 Eaun. Nap. Pesc. p. 16, t. 14, from the lliver Staffoli, an affluent of 

 the Alento, with A. 14, may prove to be the same form. 



A hyhnd between this species and Leuciscus ulliva has been men- 

 tioned, p. 235.
