Eight bank : Borba (Hoffmanns, Natterer). 



As pointed oat I.e. the binls from the Rio Madeira and lower Rio Negro are 

 snbspecifically distinct from true H. I. lugubris (Cab.),* with which H. hijpoleMC 

 Ridgw.t is synonymous. The typical race is found on the south bank of the 

 Amazons (Santarem, Paricatiiba), while a third, nearly allied form, H. btgubrii 

 berlepsclu Hellm., inhabits Northern Pern (Iquitos, Nauta). 



A review of the H. lugubris group is given Z.c]

The specimens agree perfectly with our large series from British Guiana and the 

 Canra Valley, Venezuela. In none of them is there any trace of a white inter- 

 scapular patch ; the white apical margins to the rectrices are from A to 1 mm. wide. 



H. melanopogon inhabits both sides of the Madeira. During his first trip in 

 1906, Mr. Hotfmanns obtained a series at Humaytha, on the left bank.

This bird agrees in every detail with some of Natterer's females (\Mlla Maria; 

 Vienna Museum), and differs from the preceding species by its smaller size, and by 

 having a large, concealed white interscapular patch, and broad white tips to the 

 rei-trices, about 5 mm. in width. It is a remarkable fact that the Rio Machados 

 slionM possess a species different from that found on the main stream. A siff.ilar case 

 lias already been discussed, cf Pipra aureola fasciicauda and P. a. calainae, p. 303. 



//. maculicauila is evidently the southern and western representative of
