showing some relation to A. boscas ; besides, the mottling of the head and 

 of the upper parts shows great likeness to A. boscas, with which the adult 

 birds from the Marianne Islands, when available, will have to be compared. 

 One of the specimens is very similar to the type of " A. boschas a,.freyoineti" ; 

 this is labelled as from "Malouines Islands,"' but, according to M. Oustalet, it 

 may have come from the Marianne Islands. 



Anas oustaleti. 



? Anas boschas a. freycineti, Bp. Compi. Rend, sliii. p. 649 (1556) (nomen 



nudum). 

 Anas oustaleti, Salvad. Bull. Brit. Orn. Club, n. xs. p. 1 (Marianne Is.) 



(1894). 



Female. Similar to A. supcrciliosa, but differs in being paler underneath, in 

 having less defined dusky bands on the sides of the head (one through the lores 

 and the eyes backwards, and the other through the cheeks), the light part of the 

 cheeks redder and generally spotted, and the speculum bluish purple, while 

 in A. superciliosa it is pure metallic green ; besides anteriorly to the speculum 

 there is a sufiiciently distinct white band near the tip of the greater wing- 

 COverts, which is wanting in A. superciliosa. {Mus. Paris.) 



Uab. Marianne or Ladrone Islands (Guahaw).
