Bycanistes cylindricus, Elliot, Mou. Buc. 1882. 



Hab. Liberia and Gold Coast. 



Two females, collected near Sofore Place. 



This bird seems to be rarer than either of its al- 

 ready mentioned congeners, as we have never found it at 

 Grand Cape Mount. It lives more quietly than any other 

 species of large African Hornbills and hides itself in the 

 thickest crowns of trees. 



Iris in the collected specimens reddish brown, bill horn- 

 color, feet brown. 



Buceros fistulator. 



Buceros fistidator , Cass. Proc. Ac. Nat. Sc. Philad. 1850, 

 p. 68; — Hartl. Orn. W. Afr. p. 162; — Schl. Mus. P.-

Pliolidoplialus fistulator, Elliot, Mon. Buc. 1882. 



Hab. West Africa , from Liberia to Gaboon. 



A large series , collected at Sofore Place. 



This species is the most noisy of all we met with , and is 

 exceedingly well entitled to bear its name. We saw it 

 only in the rainy months of July, August and September, 

 when it visited in small flocks with a clock-like regularity 

 some fruit-trees , overshading our thatch-house in the centre 

 of the virgin forest. 



Iris dark brown , bill black , tip and lateral spots at 

 base whitish horn-color , feet and fore-part of tarsus black- 

 ish brown , hind part lead-color.
