 holser. Proc. Biol. Soc. Wash. 30: 75-76. March 31, 1917. 

 During the past several years the writer has incidentally noted a 

 number of necessary changes in the current scientific names of birds. 

 This article is the first of a series designed to set forth these changes. 

 In the present installment the following changes are made, chiefly on 

 the ground of preoccupation: Nettion torquatum (Vieillot) becomes 

 Nettion leucophrys (Vieillot); Chloephaga magellanica (Gmelin) becomes 

 Chloephaga leucoptera (Gmelin); Cerchneis gracilis (Lesson) is renamed 

 Cerchneis araea Oberholser; Cerchneis alopex deserticola Reichenow is 

 renamed Cerchneis alopex eremica. Oberholser; and the fossil Rail us 

 intermedius Milne-Edwards is called Rallus odelus Obeiliolsei-, nom.

ORNITHOLOGY .—Washington region [winter of 1916-1917]. Harry 

 C. Oberholser. Bird-Lore 19: 153. 1917. 

 This paper is the first of a series designed to present current reports 

 on the birds about Washington, D. C. This installment treats of the 

 winter birds of 1916-1917 up to the month of March. That winter 

 proved notable for the presence of several interesting northern visitors, 

 including Loxia leucoptera, Loxia curvirostra minor, Spi?iuspinus pinus, 

 and Olor columbianus. An individual of Polioptila caerulea caerulea, 

 seen, January 1 (erroneously recorded as January 2), and one Corthijlio 

 calendula calendula, noted, January 20, also are worthj^ of special 

 mention. During the beginning of the spring migration two species 

 appeared much earlier than ever previously noted: Seirus motacilla on 

 March 17, and Nemospiza henslowii henslowii on April 1. H. C. 0.
