Genus MESOCALIUS, Cahanis et Heine. 



MM. Cabanis and Heine have established the above genus 

 for the bird I had called Chalcites osculans, and as I have 

 adopted many of the new genera into which the CiicuUdcB 

 are now divided, I have no alternative but to adopt this one 

 also. The only species of the form yet discovered is a larger 

 or more robust bird than the little Bronze Cuckoos, and it 

 also differs from them in its colouring.

Tour examples of this species came imder my notice during 

 the time I was engaged on the folio edition of the Birds of 

 Australia — one from Swan River, two killed by myself in New 

 South Wales, and one in the collection of the late H. E. 

 Strickland, Esq. ; since its completion a fine example has been 

 sent to me by G, French Angas, Esq., from South Australia.
