Genus CLIVICOLA Forster (Check-List, 2d ed., 259; Ninth 

 Suppl., Auk, XVI, Jan. 1899, i30- This becomes 



Genus RIPARIA Forster. 



Riparia Forster, Syn. Cat. Brit. Bds. 1817, 17- Type, 

 Riparia europcea Forster = ffirundo riparia Linn. 

 Riparia has actual priority, as well as page precedence, over 

 Clivicola. Forster's work was issued in two parts; Rtparta was 

 published in the first part (p. 17), and Clivicola in a separate y 

 Lued second part (p. 55), so that Riparia has clearly priority 

 over Clivicola. Hence No. 616 of the Check-List will stand as 



616. Riparia riparia (Linn.).
