Viii. INTRODUCTION. 



borrowed from the popular works of Mr. Yarrell, and of Mr. 

 Hewitson ; and occasionally from tlie writings of Mr. Tem- 

 minck and of other authors. In the enumeration of the 

 species, I have followed that given by Mr. Yarrell in the 

 second edition of his excellent History of British Birds, which 

 is in the hands of every lover of British Ornithology. And 

 I must plead that authority as an excuse for introducing in 

 this Catalogue several foreign species, which do not properly 

 belonsr to the British Fauna. Of these, however, I have 

 taken upon myself to omit the following : — Turdm Withei, 

 and T. clirysorrhcBus ; Cucuhis ylandarius ; Ardea russata ; 

 Scolopax Sabinei ; Anser yambensis, and Atias mariloides ; 

 as the doubt which seems to exist with regard to their breeding 

 place and habits, or their uncertain appearance in Great 

 Britain, render it unhkely that their eggs mil find place, for 

 the present at least, in the collection of a British Oologist. 



The genus Hemipodius, was, for the same reason, left out 

 in the Synoptical Table ; but, having, dming the progress of 

 this work, received, tlu:ough the kindness of Wm. Borrer, Esq. 

 Junr., of Cowfold, Sussex, a description of the eggs of the H. 

 tacliydromus, now in his possession, which came from the 

 neighbourhood of Oran, the genus Hemipodius has been 

 restored to its proper place, page 87 of the Catalogue.
