above the waterfalls, where, according to Mr. Hoffmanns, the aspect of the country 
changes. While the Madeira and the lower Machados flow through level country, 
there are many isolated hill-ranges and rocks on the upper course of the latter river. 
A thorough exploration of this district, from which Mr. Hoffmanns was prevented 
through bad health, would certainly yield a rich harvest to the naturalist. Santa 
Maria do Marmellos is a village on the left bank of the Madeira, and Manicoré 
(Las Oncas), where, however, but a few skins were secured, is again on the right 
side, below the mouth of the Rio Manicore, 
The greater part of the material thus gained came into the possession of the 
Tring Museum. The lot from Maruins, together with a few skins from Marmellos 
and Allianca, as well as the duplicates from Calama, have been acquired by the 
Zoological Museum of Munich, while a small number of specimens went to Count 
Berlepsch’s collection. 
Mr. Hoffmanns, I regret to say, did not live to see the results of his labours 
appear before the scientific public. Shortly after his return to Crefeld he contracted 
a severe chill, which rapidly developed into pneumonia and ended fatally on 
January 18,1909. His premature death is a serious loss to science, and especially 
to ornithology, which is indebted to him for many striking novelties, e.g. Pipra 
exquisita, P. hoffmannsi, Anoplops hofmannsi, etc. Wilhelm Hoffmanns was born 
in Crefeld, Germany, in 1865, and from his earliest youth professed a great taste 
for natural history and collecting. On leaving school he entered the service of a 
commercial establishment in Crefeld, where he remained as clerk for several years, 
but he gave up this post and went to Peru, where he made large collections of 
insects and birds. In later years Hoffmanns was more particularly interested in 
ornithology, and the long list of papers which I contributed to this journal on his 
researches speaks well for his energy and zeal, His eminently truthful character 
and straightforwardness endeared him to all who had to do with him, and will make 
us even more strongly feel the loss of so faithful a friend.

Pucheran, belongs to 7. albiventer Spix.
