184 MR. OLDFIELD THOMAS ON [NoV. 15, 



Attention having been again called to this island by the 

 remarkable ornithological discoveries made there by Capt. Boyd 

 Alexander, a special coUecting-ti'ip in the interests of the National 

 Museum was rendered possible by the generosity of our President 

 (the Duke of Bedford), of Mrs. Percy Sladen, and the Hon. Walter 

 Rothschild. A free passage to the island and back was also given 

 to the collector by Messrs. Elder, Dempster & Co., through the 

 kind offices of Sir Alfred Jones. 



The collector, Mr. E. Seimund, started in November 1903, 

 arrived in the island on December 4, and left again in April 1904, 

 so that he had in all just over four months in which to collect. 



The series he obtained is exceedingly valuable for the reasons 

 above mentioned, as he got good sets of nearly all the species 

 described so long ago by our predecessors in mammalogical 

 research ; and these cannot fail to be of constant service to all 

 workers on the subject. 



Of novelties I have only had occasion to describe two — Scoto- 

 nycteris hedfordi, Si. Fruit-Bat, ?a\diGalago demidoffi poensis, a local 

 race of the little West-African 'Galago ; but Mr. Seimund has 

 found on the island several other mammals which had not 

 previously been recorded from there. 



Our knowledge of the Mammals of Fernando Po rests chiefly 

 on the following literature : — 



Waterhouse, G. R. — Descriptions of new Mammals from the 

 Island of Fernando Po, based on specimens presented by 

 George Knapp, Esq. P. Z. S. 1838, p. 57. 

 Colohiis, Cercopiihecus. Genetta, Lutra, and Cephcdophus. 

 Waterhouse, G. R. — Descriptions of new Mammals from 

 Fernando Po, obtained by Mr. L. Eraser during the Niger 

 Expedition. P. Z. S. 1842, p. 1 24. 

 Anomalurus and Squirrels. 

 Allen, W., and Thomson, T. H. R. — Narrative of the Expe- 

 dition to the River Niger. Appendix, vol. ii. pp. 472 et seqq. 

 1848. 

 Most of the Mammals obtained on the Expedition were 

 collected at Fernando Po by L. Eraser.
