460 Descriptions of Six New Sjpecies of Birds. 



marks of \\g\t rufous ; quills blackish brown, the primaries marked with 

 light rufous spots on each web for three-fourths their length from the 

 base; the secondaries sparingly marked and ending rather broadly with 

 pale rufous ; tertiaries black with a broad stripe of light rufous on the 

 outer edge of each feather ; wing coverts black, freckled with rufous and 

 grey, and having a triangular pale rufous spot at the end of each feather ; 

 under wing coverts light rufous ; throat pale rufous, some of the feathers 

 narrowly ending in black ; on the upper part of the breast the feathers 

 are black at the base, largely rufous-white at their ends; the feathers of 

 the breast are crossed with narrow transverse black lines ; abdomen, 

 thighs, and under tail-coverts pale rufous, a few black bars on the upper 

 part of the abdomen and sides; bill black; feet flesh-color, claws 

 brown. 



Another specimen has a greater prevalence of rufous in its plumage, 

 tlie spots on the head being larger and the decided grey band on the 

 hind neck not so apparent. 



Length about 8 in. ; wing 5^ ; tail 4 ; bill y'^ ; tarsi yS_. 



Habitat — Para. Collected by Mr. v. Schulte Buckow. 



From the pure white character of the markings on the tail I 

 judge these examples to be probably males. 



The most distinguishing characteristic of this species appears 

 to be the two rows of distinct white spots crossing the tail. The 

 size is about the same as that of Aritrostomus Nuttallii, with 

 the same style of markings on the primaries, but in that species 

 the spots extend to the ends of the feathers ; in the white ter- 

 minal band on the tail they precisely resemble each other.
