Leuciscus roseus, Bonap. Faun. Ital. Pesc, from Lakes of Pied- 

 mont, is a very doubtful species. Cauestrini (Arch. p. la Zoolog. 

 etc. iv. 1866, p. 58) also is uncertain about its specific validity; 

 he says that it is, at aU events, closely allied to L. pigus. 



Chondrostoma ryzela, Bonap. 1. c. (not Agass.), or Leuciscus ryzela, 

 Cuv. & Val. xvii. p. 199 (omitted in Canestrini's list of Italian Fish,
