Genus CLIVICOLA Forster (Check-List, 2d ed., 259; Ninth 
Suppl., Auk, XVI, Jan. 1899, 131). This becomes 
GENUS RIPARIA Forster. 
Riparia FORSTER, Syn. Cat. Brit. Bds. 1817, 17. Type, 
LRiparia europea FORSTER = Hirundo riparia Lin. 
Riparia has actual priority, as well as page precedence, over 
Chivicola. Forster’s work was issued in two parts; Réiparia was 
published in the first part (p. 17), and C@vécola in a separately 
issued 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 (Lryn.). 
firundo riparia Linn. S. N. ed. 10, I, 1758, 192.
