Birds of Prince's Island. 599 



Mr. Ogilvie-Grant the description of an apparently new- 

 Grey Parrot from the island, which was published in tho 

 Bull. B. O. C. xxiii. 1909, p. 74. This bird he proposed to 

 call Psitiacus princeps. It is, of course, only a geographical 

 f(u-m of the African Grey Parrot Psiitacus erithaciis, and 

 will be found in tliis paper under the name Psittacus erithacus 

 princeps. 



Tlirougliout this paper I have given references to Count 

 Salvadori's work on Prince's Island which is quoted as 

 Orn. Golfo d. Guinea i., to the paper by Professor Bocage 

 published in 1903, and to Captain Shelley's 'Birds of 

 Africa/ so far as it goes. It is greatly to be regretted 

 that Captain Shelley's valuable work has not been com- 

 pleted. At the present time there is not a single mono- 

 graph of the Birds of Africa in the English language, 

 despite the magnificent African material in the British 

 Museum. 



The following eleven species I consider are almost 

 certainly confined to Prince's Island, although two or three 

 have been (probably erroneously) recorded as having been 

 obtained on the mainland : — 



1. Lampi'ocolius ignitus (l^iordm.). 



2. Dicrurus modest us Hartl. 



3. Uyphantornis princeps (Eonap.). 



4. Linurgu& rufobrunneus Gray. 



5. Cinnyris hartlaubi. 



6. Zosterops ficedulina Hartl. 



7. Speirops leucophcea (Hartl.). 



8. Cuphopierus dohrni Hartl. 



9. Turdus xanthorhynchus Salvador!. 



10. Psittacus erithacus princeps Alexander. 



1 1 . Haplopelia principalis (Hartl.) . 



To these must be added Estrilda astrild sonsce Reich w., 

 which is restricted to Prince's and St. Thomas' Islands, and 

 Turturoena malherbei (Verr.) inhabiting Prince's, St. Thomas', 

 and Annobon Islands. 



Alexander landed on Prince's Island on February the
