The Hon. Walter Rothschild, F.R.S., read the following 

 notes on the genus Sula : — 



In the ' Novitates Zoologicse/ vol. vi. p. 178 (1899), 

 Dr. Hartert and I applied the name Sula variegata Tschudi 

 to the "Masked Gannet^^ of the Galapagos Islands, and 

 although I corrected this error in the ' Bulletin of the 

 British Ornithologists' Club/ vol. xiii. p. 7 (1902-1903), 

 the correction appears to have been completely overlooked. 

 Mr. E. W. Gifford, Proc. Calif. Acad. ser. 4, vol. ii. p. 89 

 (1913), has again called the Galapagos " Masked Gannet '^
