IN WESTERN LIBERIA. 157 



from the Senegal , the Gold Coast and Eastern Africa in 

 our Museum , the principal color being a dark brown in- 

 stead of clay or pallide fulvo-flavesrens ^ as is said in Dr. 

 Hartlaub's diagnosis (Orn. W. Afr. p. 23). The Liberian 

 specimens suit pretty well the description of Scotornis ni- 

 gricans Salvad., given in Finsch &Hartl. Vög. 0. Afr. p. 857, 

 but as to the color of the tail , I cannot find the difi^- 

 rences upon which the mentioned authors , besides the 

 dark color, chiefly found the dark looking species. 



Like other goatsuckers they are found in brushwood 

 along the Fisherman Lake and near the sea-shore. Their 

 voice resembles much the quacking of the West African 

 bullfrog {Rana occipitalis). 



Iris brown , bill black , feet flesh-color.

Hab. From Liberia to the Congo. 



Five specimens, amongst which two quite adult, two in 

 the plumage of passage and one young, all from the St. 

 Pauls River. 



The white throat-patch seems to be peculiar not to adult 

 specimens only , but even to the youngest ones , as it exists , 

 however mixed with a few fulvous feathers , in young spe- 

 cimens , collected at Bavia. Besides the white patch , the 

 mentioned specimen is entirely grayish brown underneath. 

 In the two not fully adult specimens , both males , the 

 chest, sides of body and under tail coverts are already 

 steal-blue, the abdomen chocolate-brown. 



These fine Swallows are found along all the larger ri- 

 vers I visited in Liberia. They can regularly be seen 

 seated upon twigs and trunks of trees , rising to some 

 height above the water , from where they hunt after flies 

 and other insects , returning after a short flight to the
