Mr, G. L. Bates— Field-Notes on the 
north of Bitye, I am told, the grass-land of Northern 
Kamerun commences, and some species probably wander 
from it into the country where I have collected. 
Though this paper consists mainly of field-notes, I have 
recorded a few specimens collected since those included in 
Dr. Sharpens papers. These are mainly either additional 
examples belonging to the species already reported on, about 
which I had something in particular to say—for instance, to 
describe the stomach-contents, the nest and eggs, &c. ; or 
they are specimens of well-known species, mainly migrants 
from Europe, that had not yet been reported. No list of the 
specimens belonging to my later collections is attempted 
here. 
Having a number of eggs to describe, I have been fortu¬ 
nate in obtaining the help of Mr. W. B. Ogilvie-Grant, whose 
brief descriptions of the eggs, enclosed in square brackets, 
add much to the value of this paper. 
The arrangement followed is that of Dr. Reich enow’s 
1 Vogel Afrikas ; (cited as V. A.), and the number preceding 
the title of each species in this List is the number of the 
species in that work. 
The native names are given in square brackets, and follow 
the title.

The Wild Ducks of this country are generally seen in 
pairs, but sometimes a trio occurs—a pair with a third 
“ tagging after.” Once, in August, I saw four of them come 
and perch on the big limbs of a cotton-tree and perform 
some queer antics. They perched in pairs; the birds of 
each pair faced each other on the limb, bowed their heads, 
and rubbed each other’s bills and heads, all the while making 
a raucous noise. After keeping this up for a few minutes 
they few away. 
Two young ducklings that must belong to this species, 
which is the only one in the country, were brought to me at
