PAM: PIPRITD As 13 
Characters. The members of this genus differ at once from the typical Pifrae by their 
long, rounded tail and by their short, thick bills with the culmen more rounded. 
6? 
The bill is strong, wide at the base, and has a very distinct notch near the end of the 
tomium of the upper mandible. Nostrils large, open and oberhung by the setose nasal feathers 
Rictal bristles numerous, but rather short and soft. In the wing, the third primary is the 
longest, the second and fourth are somewhat shorter, the first equal to or rather longer than 
the sixth. Tail distinctly rounded, and at the same time slightly emarginate, for the middle 
pair of rectrices is somewhat shorter than the two following ones which are the longest. Outer- 
most rectrix about 6 to 8 mm. shorter than the submedian. Leneth of the tail about four- 
fitths of the wing. Feet rather stronger than in Pifra, toes less united. In the first species, the 
type of the genus, the sexes are different, the male being chestnut, the female olive green on 
the mantle and upper wing coverts. In the four remaining forms, which have been separated as 
Hemipipo, the sexes are alike. 
Geographical Distribution. Southern Central America (Nicaragua and Costa Rica) 
and South America down to Southeastern Brazil.

1. Piprites pileatus oe 
Pipra pileata (Natterer M.S.) Temminck. Rec. Pl. Col. t. 172, f. 1 (1822) (« Brésil », sc. Curitiba, Parana). 
Hab. The only ae exact locality is Curitiba, state of Parana, S. E. Brazil. I have also seen several 
skins of « Rio » make. and the Vienna Museum possesses a specimen said to have been collected by 
Beske near Novo Friburgo, Rio.

Pipra chloris (Natterer M. S.) Temminck, Rec. P|. Col. t. 172, f. 2 (1822) (« Brésil », sc. Ypanema, S. Paulo). 
Hab. S. E. Brazil: S. Paulo (Ypanema, Piracicaba, Iguapé, Victoria, Rio Paranapanema); Espiritu 
Santo (Victoria, Mus. Berlepsch). 
3. Piprites chloris tschudii (Cabanis). 
Hemipipo tschudii Cabanis, Journ. f. Ornith. 1874, p. 99 (Ninabamba, Central Peru). 
Hab. Central-, East- and North Peru; Eastern Ecuador and Colombia east to the Upper Rio Negro 
(Marabitanas, Rio Iganna) in N.-W. Brazil. 
4. Piprites chloris chlorion (Cabanis). 
Hemipipo chlorion Cabanis, Arch. f. Naturg. Vol. 13, 1, p. 234 (1847) (Cayenne). 
Hab, Cayenne, Brit. Guiana and North Brazil (Borba an the Rio Madeira, Cussary on the Lower 
Amazons; Manaos | 3arra do Rio Negro), and Marabitanas on the Upper Rio Negro (1). 
(1) Specimens fom Salto Girao (Upper Rio Madeira) and Engenho do Gama (on the Rio Guaporé) are exactly 
intermediate between P. chloris tschudit and P. chloris chlorion, differing from both by their decidedly smaller bill. Perhaps 
they form a distinct race.
