THIS is a very curious little Sand-Martin, and holds an intermediate position between the two sections of the genus Cotile. Thus it has a brown band on the lower throat like C. riparia, but in its small size it resembles C. minor and its allies; and like the latter group of Sand-Martins, C. congica lias no tuft of feathers at the back of the tarsus, while it differs from all the other members of the genus Cotile in having the lower margin of the bend of the wing barred with black and white.
The original specimens were obtained by Mr. P. Bohndorlf at Manyanga. on the Lower Congo, between Vivi and Stanley Pool. One of them having kindly been sent in exchange by the Berlin Museum to the British Museum, we have been able to give a description of the bird.
