 soc. London, 1872, p. 108. (Pelew Islands). 



Two specimens were taken, in the Tonj,'a Islands, a male at Xomuka, 

 2 December, 1899, and an adult bird with sex not marked, at \'avau, 

 5 December, 1899. The type-locality of Anas superciliosa Gmelin 

 Ls New Zealand and the bird from Australia which is distinctly larger 

 than the typical form has been separated i»y Mathews (Austr. avian 

 record, 1912, 1, p. .33) as J. s. rngrrsi. Polynesian birds (from Tpolu, 

 Samoan Islands, Xomuka, and Vavau, Tonga Islands, and Tahiti) 

 are similar in size to the New Zealand form, but differ from both .1. s. 

 supcrcilio.fa and .1. s. rogrrsi in being distinctly darker below and in 

 ha\'ing the throat, band on side of head, and superciliary- stripe 

 pinkish buff. In superciliosa proper and in rogersi the buff on these 

 areas is decidedly less rufescent. Measurements of the two specimens 

 in the present collection are as follows: —
