APPENDIX. 387 



Genus CICONIA. Type by tautonymy : C. ciconia (Linn.). 



Ciconia ciconia. In the 1st edition or the List the name 

 C. alba was used to avoid the use of the same generic 

 and specific name. 



Genus PLATALEA. Type by subsequent designation oE 

 Gray (List Gen. Bds. 1st ed. 1840, p. 67) : P. leucorodia 

 Linn. 



Genus PLEGADIS. Type by monotypy : P. falcinellus 

 (Linn.). Some authors have proposed to substitute 

 Egatlieus Billberg, dating from 1828, but a reference to 

 the description will show that Egatlieus Billberg is an 

 absolute synonym of Ibis Lacepede, which, according to 

 Mathews (Auk, 1913, p. 92), must be used not for the 

 Sacred Ibis (Ibis cetldopica auct.), but for the African 

 Wood Ibis (Tantalus ibis auct.). 



Genus GRTJS. The earliest use of Grus as a genus is 

 undoubtedly that of Pallas (Miscell. Zool. 1766, p. 66). 

 A reference to this work will show that it was proposed 

 for the bird known as Psopkia crepitans Linn., and 

 therefore Grus as a genus can only be regarded as a 

 synonym of Psoplda proposed by Linnseus, also in 

 1766. Gray recognised this fact in 1841, and proposed 

 Megalornis for the Common Crane, Ardea grus Linn. 



As. however, the generic name Grus has always been 

 associated with the Common Crane since the time of 

 Bechstein in 1793, and the use of Megalornis has only 

 recently been brought to the notice of present day 

 ornithologists (cf. Iredale, Nov. Zool. xvii. 1910, p. 502), 

 the Committee have decided to retain Grus as a "nomen 

 conservandum." 



Grus grus. For the reason of the change of this name from 

 Grus communis see Ciconia ciconia.
