On Birds from Efulen in Cameroon. 89 
them off. On May 23rd I took fourteen single eggs and 
substituted those of the Gull-billed Tern. On May 25th all 
the nests had been cleared and the birds driven away by a 
party of three men with large baskets. Further on we did find 
a few nests which had been overlooked^ two of which contained 
three eggs, and most of the others two — all ''^ just turned.'^ 
One set were quite white, many others white with black and 
grey markings, and few lightish brown on a buff ground with 
darker marks. The nests were substantial, some being lined 
with a few Flamingo's feathers, and all were placed on dry 
land, near the edge of a laguna. 
I should like to mention that I twice saw a black- (not 
brown-) headed Gull, which I believe to have been L. melano- 
cephalus. It was evidently not breeding and was quite 
alone, while it flew right off on our approach. 
PODICIPES NIGRICOLLIS. 
Uncommon. I saw Black-necked Grebes and found two 
nests on the Laguna Santa Olalla on April 29th which looked 
ready for laying ; but as they were still empty on May 14th, I 
concluded that the eggs had been taken. Several nests were 
found on a rushy swaimp on Lucio Real in May, the eggs 
being stained a dark mahogany colour. 
PODICIPES FLUVIATILIS. 
Numerous. Nests were found from May 2nd onward; 
one contained the large number of seven eggs. 
VI. — On a small Collection of Birds from Efulen in Cameroon, 
W, Africa. By R. Bowdler Sharpe, LL.D. 
(Plate IV.) 
Mr. G. L. Bates, who has sent us several good collections 
from French Congo and Gaboon, has now forwarded a very 
interesting series of birds from Efulen, in the German Colony 
of Cameroon, and, in a letter, has given me the following 
account of the locality : — 
" This, as you know, is a forest-country, entirely covered 
with a large and thick growth of trees, except where they
