140 THE AUSTRAL AVIAN RECORD [Vol. IV. 



p. 82, which, unfortunately, inchides lUiger's names and cites 

 references vahdating them. It may be recalled that Illiger 

 had named many new species in the Berhn Museum, but that 

 the descriptions were not pubhshed. Under the custom of 

 that age these names were accepted as valid and cited as or 

 Illiger. Until quahfied by a description or reference to a 

 published figure they are only ranked to-day as nomina nuda. 

 In the present place references to published figures are given, 

 and consequently such names are vahd, not only as to their 

 acceptable status but to their preoccupying later combinations. 

 The names noted here are : — 



p. 83. Picus auralentus 111. Charpentier vert dore Azara. 

 Picus coronatus 111. Charp. a \ entre rouge Azara Mas. 

 Turdus xanthopygos 111. Le VaiU., Ois. d'Afr., tab. 106. 

 Turdus superciliaris 111. Le VaiU. , Ois. d'Afr. , tab. 111. 

 Motacilla lugubris 111. Le VailL, Ois. d'Afr., tab. 184, f. 1. 



p. 84. Corvus sanguinicollis n. Pic a gorge ensanglantee Azara. 



There is also p. 83, Muscicapa plumbea N. Corvus ampelinus 

 111., but probably this is a nomen nudum. 



While aU these names may be synonyms, a complication 

 in connection with the correct determination of African bird 

 names being hereafter exposed, they may invalidate later 

 names as the third one, Motacilla lugubris, undoubtedly does. 

 In this instance the discovery is very useful, as for the common 

 British Pied Wagtail Temminck's name of Motacilla lugubris 

 was in use. The introduction of Temminck's name was in 

 such an uncertain state that an element of doubt must 

 commonly have been felt as to the justice of its employment. 

 Its absolute rejection on undebatable grounds is therefore 

 very pleasing, especially as the name to be used for the British 

 bird honours one of the most famous of British ornithologists, 

 as already noted, but the correct spelling is Motacilla alba 

 yarrellii. 



To the Isis 1821, as Beylage No. 1, appears a " Zweites 

 Preisverzeichniss der Doubletten des Zoologischen Museums 

 der Konigl. Universitat zu Berlin" by Lichtenstein. In this 

 List there is quite a large number of names, and it seems that
