 It agreed with D. carteri in the main points, but differed in 

 having a much shorter foot (the middle toe being at least 

 2 cm. shorter) and the hind-neck of a much greyer tint. 



After other remarks Mr. Rothschild added that it was 

 quite impossible to separate the genera Thalassogeron and 

 Diomedea, and that therefore he would henceforth unite 

 them under the oldest name Diomedea. He hoped to enter 

 more fully into this question at a future time. 



Mr. Rothschild also said that Mr. Chas. W. Richmond, 

 of the U.S. National Museum, had kindly called his attention 

 to the fact that the name Psittirostra psittacea olivacea pro- 

 posed by him in the ' Avifauna of Laysan etc/ p. 191 (1900), 

 for the Oahu form of Psittirostra, was preoccupied, as 

 Ranzani, f Elementi di Zoologia/ iii. p. 6 (1823), had already 

 made use of it as an amended name for Psittirostra psittacea 

 (Gm.). Mr. Rothschild wished to express his thanks to 

 Mr. Richmond, and proposed to rename the Oahu form 

 Psittirostra psittacea deppei, nom. nov., in honour of the 

 Prussian traveller Deppe, who had collected the only known 

 specimen of Hemignathus ellisianus and several other extinct 

 Oahu birds, of which only a few examples are now in existence 

 in various museums. 



Dr. Ernst Hartert exhibited and described two new birds 

 from the Volcano Islands, south of the Bonin Islands, as 

 follows : — 



ZOSTEROPS PALPEBROSA ALANI, n. Subsp. 



Similar to Z. palpebrosa stejnegeri from Miyako-shima 

 (South Loo Choo group), but having the bill slightly smaller 

 (about 115 to 13 instead of 14 to 15 mm.), the sides of the 

 body not isabelline-brown, but dirty white with merely a 

 brownish tinge, and the yellow of the throat apparently less 

 extended.
