Letters, Ed-tracts, and Notes. 561 



XXVIII. — Letters, Extracts, and Notes. 



We have received the following letters, addressed "To the 

 Editors of ' The Ibis ' " :— 



Sirs, — I will ask you to allow me to correct two errors in 

 my article on the breeding-seasons of birds in Southern 

 Kameroon, which I have only lately discovered. 



In the explanation of text- fig. 6, 'Ibis/ 1908, p. 562, 

 the line stated to represent the " Rainfall at Duala^' is the 

 line intended for Ebolwoa, and that stated to represent the 

 "Rainfall at Ebolwoa'^ is the one for Duala. 



In the ninth line from the bottom of the same page the 

 rainfall for the year at Ebolwoa should be 1*8 metre instead

George L. Bates.

 Madeira, and also described a third species from Teneriffe 

 which he called C bollii. 



I shall be obliged if you will insert this correction in the 

 next part of the ' Ibis/ 



Yours &c., 



F. D. GODMAN.

 spotted Bluethroat " Cyanecula suecica leucocyana," but in 

 this I cannot agree with him, for the following reasons : — I
