1926] Schmit, Crustaceans Collected by the Congo Expedition o 
examined disclosed a great many small shrimps, ten small dragon-flies, 
three spiders, a grasshopper, and a water-strider. In South Africa the 
food of the species is said to consist of fishes, frogs, small crustacea, and 
occasionally aquatic molluscs of small size. 
“Of the somewhat larger yellow-billed egret, Melanophoyx inter- 
medius brachyrhynchos (Brehm), we likewise investigated only a single 
stomach, but found in it pieces of an aqautic hemipteron and some 
shrimps. 
“The hammerhead stork, Scopus umbretta Gmelin, is anything but 
common in the forested area of the Upper Congo. Of three stomachs, we 
found two containing only dark gray, muddy refuse, such as is often 
present in the stomachs of true storks; in the third there were four 
small fish and a shrimp. 
“Of seven species of Anatidze which we secured in the Upper Congo, 
only Hartlaub’s teal, Pteronetta hartlaubi (Cassin), was found to have 
eaten a shrimp. Moreover, this occurred but once in ten stomachs ex- 
amined. Six of the stomachs, to be sure, held only coarse sand; the 
four remaining had numbers of aquatic insect-larve, mainly dragon- 
flies, many small seeds, some snails, a spider, two tiny bivalve molluscs, 
and a single shrimp. ; 
“The African sun-grebe or finfoot, Podica senegalensis senegalensis 
(Vieillot), seldom if ever dives, and is certainly not a great fish-eater. 
In the seven stomachs we studied there were invariably remains of 
insects, often beetles, but also a dragon-fly larva, a green grasshopper, 
and wings of a dragon-fly. One of the birds had also eaten a small 
crab; another two snails, some small shrimps, and a small millipede. 
G. L. Bates! has likewise recorded bits of prawns as found in the gizzard 
of Podica senegalensis camerunensis S)éstedt. 
“The foremost shrimp-fisher among the African birds I have studied 
is undoubtedly the tiny malachite kingfisher, Corythornis cristata (Pallas). 
It is often stated to eat small fish, and Dr. van Someren’ has photo- 
eraphed it with a minnow, as well as a tiny frog, in its bill. But in my 
experience in the Upper Congo it seemed far more fond of small crustacea. 
In the six stomachs of which I took special note, no fish remains were 
met with; but in four cases they were crammed with pieces of small, 
fresh-water shrimps. The two others held bits of insects, including 
beetles and one grasshopper. I do not know whether the principal 
‘tem of food has an influence on the local abundance of this small king-
