Ps. supra fumoso-nigra ; capite dorso concolore; subalaribus et axillaribus fumoso-albis. 

 Hab. in Africa occidentali trans-equatoriali. 



Adult male (type of species). General colour above sooty black ; lesser and median wing-coverts like the 

 back ; greater coverts, bastard-wing, primary-coverts, and quills black ; tail-feathers black ; lores 

 velvety black ; cheeks, ear-coverts, and under surface of body sooty black like the upper surface ; 

 under wing-coverts and axillaries pale smoky brown ; quills dusky below, browner along the 

 inner web: "eyes black" [Petit). Total length 5'8 inches, culmen 0\25, wing 4"05, tail 2 - 9, 

 tarsus 0'35. 



Adult female. Similar to the male in colour, but wanting the serrated edge to the outer web of the first 

 primary. Total length 5 - 2 inches, culmen 0\25, wing 3'55, tail 2'5, tarsus 04. 



Young. Similar to the adult, but not so glossy; below much paler and more earthy brown. 



Hub. West Africa; from the Congo to Gaboon. 



This species was discovered by Mr. Louis Petit at Landana on the Congo, and was also 

 met with by Dr. Lucan at Chinchonxo in the same district and about the same time. 

 We have recently seen several specimens also collected by Mr. Petit in the Congo region. 

 Dr. Oustalet records a specimen from Sam-Quita in Gaboon, where it was obtained by 

 the well-known traveller Marche on the 18th of December 1875. 



Of all the rough-winged Swallows of Africa this is one of the most distinct, being 

 distinguished by the pale smoky-brown axillaries and under wing-coverts. The nearest 

 ally is Ps. cmtmorii, which, however, has the under wing-coverts pure white. 



The figure in the Plate is drawn from a specimen in the British Museum, and the 

 descriptions are taken from the ' Catalogue of Birds.'
