99. Buttikofer on Birds from Liberia. 



[Zoological Researches in Liberia. Fourtli List of Birds. By J. But- 

 tikofer. Notes Leyden Mus. xi. p. 113.] 



Mr. F. X. Stampfli, who was left in Liberia by Mr. Biit- 

 tikofer in 1887 to continue his zoological researches, has 

 now returned finally to Holland, and has brought with him 

 a collection of about .250 specimens of birds, representing 

 92 species, of which one {Bubo lettii) has already been de- 

 scribed as new, and eleven are additions to the Liberian avi- 

 fauna. A list, with critical notes, is given of the whole col- 

 lection, and Bubo lettii is figured. The paper is concluded 

 with a general summary of all the species met with by 

 Mr. Buttikofer and his assistants in Liberia, 229 in number. 

 About 17 others, mentioned as having occurred in Liberia by 

 previous authors, have not been obtained by Mr. Buttikofer 

 and his friends.

[Ou a new Collection of Birds from South-western Africa. By J. 

 Biittikofer. Notes Leyden Miis. xi. p. 65.] 



Mr. van der Kellen, whose previous collection of birds 

 from the interior of South-west Africa has already been 

 noticed {above p. 245), has sent to the Leyden Museum 

 another series from Humpata, on the Upper Cunene. It 

 contains 267 specimens, which Mr. Buttikofer refers to 103 

 species. Of these 49 are additional to the former list, and 

 two {Lophoceros alboterminatus and Francolinus jugularis) 

 are new to science ; the latter is figured. The species now 

 known from the Upper Cunene are 180 in number.
