On the Birds of St. Thomas' Island. 89 



IV. — Report on the Birds collected by the late Mr. Boyd 

 Alexander {Rifle Britfade) during his last Expedition to 

 Africa.— Vart 11.^ The Birds of St. Thomas' Island. By 

 David A. Bannerman, B.A., M.B.O.U., F.R.G.S. 



In the previous number of ' The Ibis ' I publislied the first 

 of a series of five papers dealing with the last collections 

 formed by Boyd Alexander. 



Following the same plan as I adopted when describ- 

 ing "The Birds of Prince's Island/^ I have included an 

 excellent account of the island of St. Thomas from ' Boyd 

 Alexander's Last Journey/ which his brother, Mr. Herbert 

 Alexander, has kindly permitted me to make use of. 



A complete list of the species of birds found on St. Thomas 

 is given in the following pages, irrespective of whether 

 Alexander obtained examples or not. An asterisk, attached 

 to a species, signifies that the bird is represented in the 

 Alexander collection, and in every case the specimens which 

 he procured are enumerated. 



I must again acknowledge the invaluable papers on the 

 avifauna of the islands in the Gulf of Guinea published by 

 Count Salvadori, which I have constantly consulted while 

 working out the Alexander collections. 



As in the case with Prince's Island, Count Salvadori has 

 included in his paper a complete " Bibliography " of the 

 literature dealing with St. Thomas up till 1902. 



While working out the birds of this island, I have 

 particularly made use of the following works : — 



BocAGE. Jorn. Sci. Lisboa, 1891, pp. 77-87 ; id. 1905, pp. 72-90. 

 Salvadobi. Mem. Accad. Sci. Torino, 1903 (Orn. Golfo d. Guinea, 



ii. pp. 17-45). 

 Shelley. Birds of Africa, vols, i.-v., 1896-1912. 

 Keichenow. Vogel Afrikas, vols, i.-iii., 1900-1905. 



In the first of these papers Prof. Bocage gives excellent 

 notes on the nidification of the majority of the species with 



* For Part I. see •' Ibis,' 1914, pp. 596-631.
