Birds of Prince' s Island. fil5 



not help thinking there must be some mistake about this 

 bird, or otherwise it must be a very rare species." 



From the above remarks it will be gathered that Turdus 

 0. xanthorhynchus is a very shy and retiring bird, and, if a 

 genuine resident on the island is even more locally distributed 

 than Signor Fea imagined to be the case. I do not myself 

 doubt that the Thrush is to be found there, although it may 

 be many years before another example is obtained. 



16. Saxicola rubetra, 



Fratincola rubetra (Linn.) ; Salvadori, Orn. Golfo d. 

 Guinea, i. 1903, p. 6 ; Bocage, Jorn. Sci. Lisboa, 1903, 

 p. 49. 



The Stonechat has been recorded from Prince's Island by 

 Keulemans (Nederl. Tijdschr. Dierk. iii. 1866, p. 391). 



17. Delichon nrbica. 



Chelidon urbica (Linn.) ; Salvadori, Orn. Golfo d. Guinea, 

 i. 1903, p. 4 ; Bocage, Jorn. Sci. Lisboa, 1903, p. 48. 



Evidently a very rare and accidental migrant. 



Keulemans obtained a single example of the House-Martin 

 on Princes's Island in January. The skin was not preserved, 

 but Keulemans seemed perfectly certain of the correct 

 identification. The House-Martin does not appear to 

 migrate down the west coast south of Gaboon. In fact, the 

 above example seems to be the only record from the GulU 

 of Guinea. D. urbica is said to be common in Senegal ia 

 winter, and I have in certain years seen numbers passing 

 through the Canary Islands on their way north during the 

 spring migration. They do not appear to pass through 

 Sierra Leone according to Kelsall. 



18. Cotile ciucta. 



Cotijle eques Hartlaub, P. Z. S. 1866, p. 325. 



Cutile cincta (Bodd.) ; Salvadori, Orn. Golfo d. Guinea, 

 i. 1903, p. 4 ; Bocage, Jorn. Sc. Lisboa, 1903, p. 48. 



It is quite possible that Cotile cincta may be found in 

 Prince's Island throughout the year. Both Dohrn and 

 Keulemans found it to be rare near the coast, but the latter
