Fuligula fuligula (Linneus).

3 ¢. Singa, Jan. 1921. The male has the underparts and parts of the tail stained a deep rusty chestnut. I have never seen a duck stained to such an extent. The new feathers which are appearing in the tail and on the abdomen are normally coloured.

Fuligula brunnea (Hyton). A live bird from Um Ruaba, Kordofan, obtained Dec. 1920: This example, Flower tells me, was quite a young bird; he saw it in the yard of an Arab’s house with young specimens of Dendrocygna.

This seems to be a very great northern extension of the range of this duck.

I use HEyton’s name for this species as, owing to lack of literature, I do not know if Neuwied’s name erythrophthalma is applicable as stated by Sharpe, ‘ Hand-list of Birds,’ vol. i.

Charadrius alexandrinus alexandrinus (Linnzeus).

2. Sennar, Jan. 1921. This example has a wing of 111 mm., and is undoubtedly of the typical form. Specimens from Egypt vary in wing measurement: out of a large series, eight in the Giza Museum are from 100 to 104 mm., but one of these was breeding with long-winged birds.
