H. melanopogon, but I do not venture to employ a trinomial name on the evidence 

 of our present knowledge. H. maculicatida ranges from the Rio Machados and the 

 headwaters of the Madeira (Rio Guapore, etc.) through AVestern Brazil (Purus, 

 Jurua ; 01iven(;a on Ihe Rio Solimoens) to Eastern and Northern Peru. 

 H. 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 S. Isabel (right side). 

 //. maculicauda, however, has also been found in the Para district (Prata, Rio 

 Acani, Capim) * and on the Tapajoz.f Three specimens before me, a couple from 

 Para and a male from Goyaua, Tapajoz, 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.

1 have shown J T. melanoleiica to be synonymous with II. hemileuca. Mr. 

 Hoffmanns did not meet with this rare species, which is still only known from the 

 type, olitained by E. Bartlett ; the two adult males taken many years ago by 

 Natterer near Borba ; and the type of J/y/vrtOf/wi/iei- kijpoU'iicus \ from Reyes, N.E. 

 Bolivia. There is a fifth, hitherto unrecorded specimen in (!onnt Berlepsch's 

 collection. It was secured in Eastern 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 Uaupes, and a female at Borba, in January 183U. The type of Dichrozona 

 zononota Ridgw. || was shot by Mr. C. B. Riker at Diamantina, near Santarem, on 

 the Rio Tapajoz, and the original examples of Htjpocnemis stellata Scl. & Salv. 1' 

 were taken at a place called Sarayai^u, Eastern Ecuador, by one of Buckley's 

 hunters. More recently, I have examined an immature female collected at Uby 

 no Cachoeira, Rio Punis, June 17, 19U3, and preserved in the Para Museum.**
