1. PiPRA OPALIZANS. (Plate II.) 



In the second part of his 'Zur Ornithologie Brasiliens/ 

 published at the end of 1868 (pp. 128, 186-187), Herr 

 August von Pelzeln made known a new species of Pipra 

 from a MS. descri[)tion of Johann Natterer, who collected 

 a single specimen of this bird in the neighbourhood of Para, 

 Lower Amazons. Unfortunately this single individual was 

 lost, and Herr von Pelzeln was obliged to form a diagnosis 

 from Natterer's MS. description, which, nevertheless, was 

 very full and detailed, and now proves also to be quite 

 correct. 



In 1888 Mr. Sclater, when writing his Catalogue of the 

 Piprida in the British Museum (vol. xiv. p. 292), remarked 

 in a footnote that he was not acquainted with Pipra opali- 

 zans, Pelz., and nothing has since been published about 

 that species. 



After this, a young entomological collector, Herr Albert 

 Schulz^ of Prussia, intending to collect birds for me on the 

 Lower Amazons, asked me for descriptions of rare birds 

 inhabiting that country, and when leaving for Para, besides 

 descriptions of other birds, took with him a diagnosis of 

 Pipra opalizans. The first collection I received from him 

 was not very promising, but the second contained a specimen 

 of Pipra opalizans. 



Before receiving this collection, I had a letter from 

 Mr. Schulz with a list of its contents. He had tried to 

 name his species after the descriptions in his hands, and I 

 found the name of Pipra opalizans in his list. I confess I 

 did not believe in the correctness of this identification, and 

 was really surprised when, on opening the box, I found a 

 true Pipra opalizans, which proved to be one of the finest 

 and most singular birds which I ever had before my eyes. 



The bird obtained by Schulz is evidently a male, and is 

 no doubt in perfect plumage. The upper parts, including
