H. melanopogon, but I do not venture to employ a trinomial name on the evidence 
of our present knowledge. HH. maculicauda ranges from the Rio Machados and the 
headwaters of the Madeira (Rio Guaporé, etc.) through Western Brazil (Puris, 
Jurud; Olivenca on the Rio Solimoéns) to Eastern and Northern Peru. 
Hl. melanopogon inhabits the countries north of the Amazon Valley (Mexiana 
Island, the Guianas, the Orinoco and Rio Negro district), but descends along 
the Madeira as far as Humaytha (left bank), Calama and 8. Isabel (right side). 
H1. maculicauda, however, has also been found in the Para district (Prata, Rio 
Acara, Capim)* and on the Tapajéz.f Three specimens before me, a couple from 
Pard and a male from Goyana, Tapajéz, agree with Upper Amazonian skins in 
size and in the possession of a large white interscapular patch ; but the white ends 
to the rectrices are decidedly narrower, though much wider than in H. melanopogon. 
A larger series from the Lower Amazons is required to prove the constancy of this 
character or otherwise.

lL have shownt 7. melanoleuca to be synonymous with H. hemileuca. Mr. 
Hoffmanns did not meet with this rare species, which is still only known from the 
type, obtained by BE. Bartlett ; the two adult males taken many years ago by 
Natterer near Borba; and the type of Myrmochanes hypoleucus § from Reyes, N.E. 
Bolivia. There is a fifth, hitherto unrecorded specimen in Count Berlepsch’s 
collection. It was secured in Eestern Ecuador by one of the men employed by 
the late-Henry Whitely, of Woolwich, but its exact place of capture is not 
known. |

Rio Madeira: Borba (Natterer). 
This species is represented by but few specimens in scientific collections. 
Natterer obtained a male at Sao Joaquim on the upper Rio Negro, near the mouth 
of the Uaupés, and a female at Borba, in January 1830. The type of Dichrozona 
zononota Ridgw.|| was shot by Mr. C. B. Riker at Diamantina, near Santarem, on 
the Rio Tapajéz, and the original examples of Hypocnemis stellata Scl. & Salv. 1 
were taken at a place called Sarayacu, Hastern Ecuador, by one of Buckley’s 
hunters. More recently, I have examined an immature female collected at Uby 
no Cachoeira, Rio Parts, June 17, 1903, and preserved in the Paré Museum.** 
Prof. von Ihering records a male from the Rio Jurua, secured May 30, 1902.tT]
