on the chest ; flanks striped as in P. sagittatus. Prof. Ihering has lately separated a 

 third form from Northern S. Panlo as P. s. var. sharpei on account of the feathers of 

 the chest and breast having no sagittate markings, bnt two transverse black bars, 

 sometimes nnited by a black median stripe.* 



The careful examination of a very large series, including the types of P. guttifer 

 and P. sagittatus, kindly lent by my friend Mens. M(^negaux, of the Paris Mnsenm, 

 and the original specimens of P. sharpei Ih., obligingly forwarded by Prof, von 

 Ihering, has convinced me that these supposed three forms are really bnt one, the 

 noted differences being partly due to individual variation, partly due to age. This 

 is conclusively proved by the ten specimens from Goyaz examined by me — namely, 

 the two types from the Paris Musenm, two skins (<? fere ad., ? ad.) obtained by 

 Natterer, and six secured by Mons. Baer. In this series are represented the three 

 phases characterised above, as well as several intermediate stages. The same 

 variation is to be noticed in three examples taken by Mons. Robert on the Rio 

 Jordao, N.W. Minas Geraes. 



As to P. caipira I have also not the slightest doubt that it is based on a young 

 bird of the same species. Tlie Tring Musenm possesses six skins from the typical 

 locality (Victoria), received from Mr. W. F. H. Rosenberg (coll. Hempel). None of 

 them is quite adult, all showing a distinct buff wash on the belly, as is also the case 

 in immature birds from G(5yaz and Mattogrosso. The series differs in no way from 

 other specimens in corresponding plumage, and presents the same variation with 

 regard to the black markings on the lower parts. 



The range of P. guttifer is thus as follows : 



State of Goyaz : City of Goyaz (Natterer, Baer, Casteluau et Deville), Rio 

 Tocantins (Casteluau et Deville), Faz. Esperani,a (Baer). N.W. Minas Geraes : 

 Rio Jordao (Robert). Northern S. Paulo : Jaboticabal (Lima), Baun'i, S. .leronymo 

 (Garbe), Avanhandava, Rio Tiete (Garbe), Victoria = Botncatu (Hempel). Matto- 

 grosso : Nas Frechas, CnyabA (Natterer), Chapada (Smith).

In addition to these, the Tring Mnsenm possesses 1 cj ad., 2 ¥ ? ad. from Rio 

 Jordao, prov. Aragna}', Minas Geraes (A. Robert coll.), and an adult bird, not 

 sexed, obtained by Mr. Gustav Garlepp at Santa Cruz de la Sierra, Eastern 

 Bolivia. 



* The colour of the upper tail-coverts, another of the alleged specific characters, is of no importance 

 in these birds. 



f It the type really came from Brazil it must have been obtained somewhere on the Amazons, 

 for tiie original description, as well a-s the plate in the Monogr. Rhamphatt. ed. 1. pi. 13, unquestionably 

 refer to the northern form.
