58 ZOOLOGICAL RESEARCHES IN WEST AFRICA. 



one specimen was secured, whicli belongs to the rare spe- 

 cies Centropus francisci. A fine series of the small Gla- 

 reola niichalis was collected, which up to the present day 

 was only known from a single specimen killed on the banks 

 of the Upper Nile. However all the specimens collected 

 in Liberia have a rufous instead of a white collar , for 

 which reason I shall designate them by the name of Gla- 

 reola nuchalis liheriae. Eight species of Hornbills inhabit 

 the country , and among them are the two rare and in- 

 teresting species which I have formerly described as Buce- 

 ros pulchrirostris and B. nagtglasii. A fine series of Bu- 

 ceros semifasciatus furnishes the ultimate proof that this 

 species cannot be confounded with Buceros /asciatus , as 

 has been proposed by certain modern ornithologists. 



The present note is intended to serve as an introduc- 

 tion to the description of the new or interesting animals 

 for which we are already indebted to our collectors. 



An extract of Mr. Biittikofer's Journal of this first year's 

 work in Liberia will be published in the Journal entitled 

 "Tijdschrift van het Aardrijkskundig Genootschap te Am- 

 sterdam." 



The duplicates in the collections both of the mammals, 

 birds and some of the other classes of animals have been 

 exclusively intrusted for sale to the well-known firm of 

 Mr. W. Schlüter at Halle.
