Birds of Southern Cameroon. 
from T. olivaceus , an example of which I procured at Efulen 
some years ago ( cf . ‘ Ibis/ 1904, p. 96). 
The immature specimen (No. 4271) shews no marked 
difference in plumage from the adult; the difference in the 
length of the bill is, however, remarkable, and so is the 
difference in the colouring of the naked skin of the head ; in 
the young bird this is uniform dark purplish blue, while in 
the adult it is black with some light blue spots. 
I was informed that the young bird (No. 4271) was one 
of two individuals which were seen standing on the bank of a 
stream, and thrusting their bills into the water. No. 1177 
(‘ Ibis/ 1907, p. 423) was likewise said to have been one of a 
pair seen to fly up into a tree from the bank of the same 
stream. The stomachs of all contained some worm-like 
creatures, or bits of shell and perhaps insects, along with a 
quantity of mud and decaying leaves; and even the intestine 
of one seemed to be full of mud. 
AbDIMIA ABDIM1I. 
Reichenow, Y. A. i. p. 343. 
No. 4170. ? . Bitye, R. Ja, April 18, 1910. 
This is the only specimen I have ever met with in 
Cameroon, and the natives with whom I talked had never 
seen one. It appeared at the end of the longer dry season, 
the rains of April were late in beginning last year. That is 
the period of greatest drought all over Africa north of the 
equatorial forest-belt, and the Stork had evidently been 
driven by lack of food to wander so far. Its stomach was 
full of grasshoppers. It settled in a large clearing that had 
recently been burned off; and when disturbed did not fly 
to the surrounding forest, but remained on the cleared 
land.
