Hab. Ashantee (Pel) ; Fantee (Sharpe) . 



Bycanistes cylindricus was first described by Temminck in the e Planches Coloriees,' and 

 the bill figured. The species bears some resemblance to B. cristatm, but can easily be 

 distinguished by the shape of its bill and colouring of its tail. Like all the members of this 

 section, there is no difficulty with the synonymy, the bird having been always designated by the 

 name first given. It is a native of the western coast of Africa, and apparently restricted to the 

 Ashantee and Fantee countries. At least these are the points from which specimens have been 

 received ; but it is probable that, when the distribution is fully known, it will be found to be 

 considerably more extensive than at present supposed. Nothing whatever, I believe, has been 

 recorded regarding the economy or habits ; and we can only conjecture that they would resemble 

 those of the other members of the genus. 



Bill and casque brownish yellow, tip of bill light yellow. The casque rises from the base of 

 culmen, projects backwards over the head, and then inclines forward for two thirds the length of 

 the bill, terminating at a right angle to it. The casque is divided into two portions by a deep 

 furrow running from the posterior to the anterior face, above which it is rounded. The sides 

 have several deep irregular grooves. The mandible has also four or five diagonal furrows at its 

 base. Head and occiput covered by a long greenish black crest. Neck, back, breast, wings, and 

 thighs black with bluish green reflections. Apical portion of secondaries and primaries for one 

 third their length, abdomen, upper and under tail-coverts, and lower part of rump pure white. 

 Tail white, with a very broad central black band with greenish reflections. Tarsi and feet 

 black. 



Total length 31 inches, bill at gape 5, casque on top 4J, height over nostril 2J, height of 

 bill and casque at base 3^, wing 13, tail 10J, tarsus 2.
