ü ZOOLOGICAL RESEARCHES 



(1885) on the birds of Liberia, Büttikofer has given a very 

 clear and interesting introduction treating on the physical 

 condition of Western Liberia. In an expected paper Büt- 

 tikofer intends to enter in some details on the Eastern 

 parts of that country , the field of his later investigations ; 

 he will adjoin a sketch of the latter part of Liberia em- 

 bracing the Junk-, Du Queah- and Farmington Rivers. 



Nearly every species he procured has given opportunity 

 to Büttikofer to make biological observatious, which he 

 always very eagerly collected and which I add hereaf- 

 ter in the German language. If we peruse the following 

 pages and Büttikofer's papers on the Liberian birds 

 and we consider that Reptiles and Fishes, Mollusks and 

 Insects have been collected by our travellers on the same 

 large scale and in the same exhausting manner, then we 

 must wonder that Büttikofer has found time for such ex- 

 tensive observations concerning Botany , Ethnology , Anthro- 

 pology , Geography , Meteorology and Philology as he made 

 and which he partly published in a Dutch journal (Tyd- 

 schrift van bet Nederlandsch Aardrijkskundig Genootschap , 

 1883, Bij blad n° 12). I think that no traveller before 

 Büttikofer , under such bad couditious and in such a mur- 

 derous climate has gathered such an enormous mass of 

 données in every branch of science and that in the short 

 time of a few months.

Scheint tiefer in Innern ziemlich staudfest und allgemein 

 bekannt zu sein , wahrend er im Küstenstrich nur eine spora- 

 dische Erscheinung ist. In Goro und Fali gelang es mir über 

 den Chimpanzen — denn nichts Anderes ist der dort durch 

 Jedermann gekannte baboon — einige Nachrichten einzu- 



yjotes from the Ley den ÜVIuseuiu, Vol. X.
