This new species is named after Mr. Albert Schulz, who in 

 the same place rediscovered the famous Pipra opalizans.

 [Geo. K. Cherrie leg. No. 8057.] 



I have named this curious bird in honour of the Hon. 

 Walter Rothschild, who kindly allowed me to describe it. 



The Cherrie collection contained only a single specimen 

 which is the type of the above description, and this, unfor- 

 tunately, has the bill somewhat injured and rather com- 

 pressed laterally. I have thought it necessary to make it the 

 type of a new genus, because, although allied to Lojyhotriccus 

 spicifer (Lafr.), it differs so much from it by its wing- 

 formula, by its more even tail and by the want of a crest, 

 that it cannot, in my mind, be placed in the same genus. 



The wing formula is a rather curious one, some of the 

 secondaries, viz., the 14th, 15th, and 16th, being as long as 

 the longest primaries, while the 9th, 10th, and 11th are 

 much abbreviated and of nearly equal length. The 3rd, 4th, 

 and 5th jn-imaries are the longest of all and of about
