392 APPENDIX. 



Genus NUMENIUS. Type by tautonymy : JV. nwnenius 

 Briss. = iV. arquata (Linn.). 



Genus HIMANTOPUS. Type by tautonymy : H. Jiinlantopus 

 (Linn.). 



Himantopus himantopus. For the reason of the change of 

 this name see Ciconia cicorna, p. 387. 



Genus EECUEVIROSTEA. Type by monotypy' : R. avocetta 

 Linn. 



Eecurvirostra avocetta. The specific name is spelt by Lin- 

 naeus with an " s " in the 10th edition and with a " c " 

 in the 12th. The latter is obviously correct, and we 

 may accept Linnaeus' own correction. 



Genus CHAEADEITJS. There is some disagreement in regard 

 to the type o£ (his genus. By subsequent designation 

 of Gray (List Gen. Bds. 1st ed. 1840, p. 65) it is 

 C. pluvialis Linn. = C. apricarius Linn., the Golden 

 Plover, and this decieion is followed by Sharpe in the 

 Catalogue of Birds and by the A. 0. U. Check-List. 



By Linnean tautonymy the type appears . to be 

 C. Idaticula, but the Committee have decided in this 

 case to adhere to the older decifion. Should Charadrius 

 be used for the Einged Plover, Pluvialis is available for 

 the Golden Plover. 



Charadrius apricarius. Linnaeus names the Golden Plover 

 twice — as C. apricarius in the summer plumage on 

 p. 150 ; as C. pluvialis in the winter dress on p. 151. 

 Under these circumstances the first name has pre- 

 cedence, and must stand. 



Genus SaUATAEOLA. Type by monotypy : S. sguatarola 

 (Linn.). 



Squatarola squatarola. Linnaeus in his 1758 edition described 

 the Grey Plover in winter jilumage under the name 

 Tringa squatarola. In his 1766 edition he refers to it
