species of Psalidoprocne, which seem to have learned the 

 secret of perpetual motion. On my last trip to the Ja I 

 several times saw examples of Hirundo gordoni on the clayey 

 paths getting mud on their bills. No. 462 was shot while 

 doing this, and a lump of mud was found on its bill. 

 Nos. 700-702 were caught from a colony which was nesting 

 in a hollow tree near the Ja. I have never obtained these 

 Swallows about Efulen, where they must be less common 

 than further inland. But the old nest in which the specimen 

 of Cypselus batesi was caught, near Efulen ('Ibis/ Jan. 1905, 

 p. 91), must have been that of this or a similar Swallow.]

This species might have been expected to be C. major of 

 Hartert (Bull. B. O. C. xiv. p. 73, 1904), from Angola, but 

 it is a smaller bird than C. natalensis, not larger. Like the 

 Angolan species, it has a narrow line of yellow running^from 

 the lores above the eye. The Camaroon birds are much 

 darker than any of the other species, with the crown not 

 perceptibly differing from the back in colour, but being of a 

 dark olive-brown tint, inclinimg to dull olive-yellow.
