LIST OF DIURNAL BIRDS OF TRET. 



1 Included by Mr. Sharpe amongst the synonyms of U. anthracina. 

 ^ Here described under the name '' Morphnus iiruhitinga." 



2 Here referred to the genus Hypomorphnus. 

 * See Appendix I. 



^ Spix refers this species to the genus Aquila, Temminck to Falco, and D'Orbigny to 

 Morphnus, all three using the specific name " v.rubifinga." 



^ Here referred to JJruhitinga sonura, with which it is also united by Mr. Sharpe. 



' Mr. Sharpe includes this species, though somewhat doubtfully, amongst the syno- 

 nyms of H. coronatus. 



8 Here figured under the name of ^'Circa'etus solitarius." 



^ The Notes here referred to relate to " Plangus neogcsus" of Sundevall, which I 

 now think was probably founded on the first plumage of H. coronatus, or possibly of 

 H. solitarivs. 



'0 D'Orbigny refers this species to the genus Circaettis.
