IN WESTERN LIBERIA. 209 



than 30 specimens shot and examined during my stay in 

 Liberia, there was not one that showed any tendency of 

 the tail-feathers to become entirely white, like Dr. Rei- 

 chenow thinks they will regularly do in the adult stage 

 of plumage. Certainly his specimens with entirely white 

 tail-feathers represent the adult , those with more or less 

 white on the terminal part, the young stage of the true 

 B. fasciatus, which is at once distinguished by the color 

 of the bill, which is red at the point and the lower sur- 

 face of the lower mandible in the adult stage. 



This species of Hornbill is the commonest of all in Li- 

 beria. Although an inhabitant of the primeval forest, it 

 visits isolated trees and small groups of trees near the 

 plantations of the Negroes, where it is easily observed by 

 its hoarse, disagreable cry, which resembles much that of 

 aur Magpie. Its principal food consists of palmnuts. 



Iris coffee-brown , bill in young specimens entirely yel- 

 lowish white, in adult ones the point pure black, which 

 color extends farther on at each side along the ridge, at 

 the edge of the bill and from there in an oblique band 

 downward on the lower mandible; feet greenish brown. 

 A young but full-grown female has the partly bare skin 

 on the neck chrome-yellow.

Hab. West Africa, from Liberia to the Loango Coast. 



Male and female, collected at Sofore Place. 



A comparison of my two specimens with the type of 

 B. Nagtglasii and another example labelled »West Africa" 

 show that they all agree perfectly with both above men- 

 tioned descriptions, given by Gould and Schlegel. The 

 description by Schlegel is a good completion of that from
