above the waterfalls, where, according to Jlr. Hofl'inaiins, the asjiect of tiie coiiiitry 

 changi's. While the Maileira anil tlie lower Machados flow through level comiti'V, 

 there are many isolated hill-ranges and rocks on the npper course of the latter river. 

 A tborongh exploration of this district, from which Mr. Hoffmanns was prevented 

 througli bad health, would certainly yield a rich harvest to the naturalist. Sauta 

 Maria do Marmellos is a village on the left bank of the Madeira, and Manicore 

 (Las Oncas), wliere, liowever, but a few skins were secured, is again on the right 

 side, below the month of the Rio Manicore. 



The greater part of the material thus gained came into the possession of the 

 Tring'Mnsenm. The lot from IMarniiis, together with a few skins from Marmellos 

 and Allianca, as well as the dujilicates from Calama, have been acijuired by the 

 Zoological Museum of Munich, while a smill number of specimens went to ('ouiit 

 Berlepsch's collection. 



Mr. Hofi'manns, I regret to say, did not live to see the results of his labours 

 appear before the scientific ])ublic. Shortly after his return to Crefeld he contracted 

 a severe chill, which rapidly developed into i)neumonia and ended fatally on 

 Jannary 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 

 ej^qiiisita, P. Iiojf'mrinitsi, Anoplops liojfmannsi, etc. Wilhelm Hoffmanns was born 

 in Crefekl, 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 straightforwarilness 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.
