V. Duivenbode, Eiedel and Platen investigated by Prof. W. Bias ins; neither 
was it obtained there by Meyer during his stay of about twelve months, nor by 
Dr. Guillemard during the cruise of the “Marchesa”, nor by the older travellers. 
Only three naturalists were more successful, two or more specimens were shot 
at Macassar by Mr. Wallace, from whom the British Museum received its two 
specimens (? the same) ; another was obtained at the same place by Beccari. 
There is also a specimen from Celebes in the Norwich Museum, as we learn 
from Mr. Gurney. The only record of its occurrence in North Celebes appeared 
to consist in the single specimen in the Leyden Museum, until two specimens 
from Lotta near Manado were sent to us in 1894. Possibly its rarity in collections 
has something to do with the difficulty of invading its mountain haunts.
