Charadrius Ϯ Long-billed Plover C. placidus) Gr. παρ par near; genus Oxyechus Reichenbach, 1853, plover; "I have already said that A. placida would be better placed in Oxyechus, but here again it would be better to signalise the differences by means of a subgeneric name. I therefore introduce PAROXYECHUS with A. placida Gray as type. The names would be— Oxyechus vociferus. -[do.]- (Paroxyechus) placidus." (Mathews 1913).
