1 think that their specific differences are clearly pointed out 

 in my review. As Cassin's name " albocristatus" was 

 bestowed on the Liberian species, the southern form 

 (Camaroon to Congo) must stand as O. cassini Finseh.

Sirs, — I wish to draw attention to two errors in our 

 paper which appeared in ' The Ibis ' last month on the

 the note, as originally written. 



The last paragraph on page 61 and the first paragraph on 

 page 62 should have appeared as the second and third para-

 paragraph of the article on Rhynchcea capensis (p. 61) that 

 accidentally got into the British Museum along with some 

 eggs presented by me in 1894 or 1895, and was unfortu-

 Centropus sinensis, and was intended to refer to Cuckoos 

 generally. The word used was " the," not iC these." 



As the note stands it refers only to Cuculus canorus and 

 C. intermedins. I once, however, obtained a clutch of the
