32. Duerden on the Plumages of the Ostrich. 



[The Plumao-es of the Ostrich. By Prof. J. E. Duerden, M.C, Ph.D. 

 Smiths. Rep. for 1910.] 



This is a separate copy (with corrections) of an article 

 which appeared in the ' Agricultural Journal of tlie Union of 

 South Africa' in 1910. Prof. Duerden states that four well- 

 marked plumages can be distinguished in the Ostrich, which 

 he denominates the "natal/' the "chick," the "juvenal/' 

 and the " adult." He describes these four plumages at full 

 length. We have no doubt that his descriptions are 

 accurate and his figures correct. But we venture to ask 

 him to study the works of Nitzsch, Parker, Garrod, Forbes, 

 and other pterylographists and ascertain how far his views 

 coincide with theirs. This essay is intended for the use 

 of the Ostrich-farmers of South Africa. 



33. Fleming on a supposed 7iew Duck. 



[A new Teal from the Andaman Islands. By J. H. Fleming. Proc. 

 Biol. Soc. Washington, xxiv. p. 235 (1911).] 



Mr. Fleming describes as " sufficiently different for a new 

 subspecies " Polionetta albigularis lencopareus, allied to Nettion 

 albigulare of Hume, but larger and more white. He bases 

 the new form on specimens obtained on North Reef Island 

 of the Andaman group, but admits that a specimen from 

 North Andaman Island is intermediate.
