452 Bangs and Noble, Birds of Peru. [oct. 



Formicariidae. 



Taraba melanura debilis Berl. & Stolz. Three specimens, an im- 

 mature male and adult male and female, Bellavista, September. 



Apparently our specimens belong to this form, described from Central 

 Peru, agreeing much better in size and proportions with it than with true 

 T. melanura (Gould) of Ecuador. 



Thamnophilus radiatus variegaticeps Berl. & Stolz. One adult d\ 

 Bellavista, September 29. Our skin agrees fairly well with the descrip- 

 tion of this form from Central Peru. 



Erionotus albiventris (Tacz.). Seven specimens, an immature male 

 and adults of both sexes, Perico, September. 



This is apparently a very distinct species; the male has a large white 

 belly patch and a pale gray throat, in the female belly and throat both are 

 whitish. 



Dysithamnus semicinereus Sclater. One male (not quite adult, 

 still having a little yellow on lower belly), Perico, September 12. 



In spite of Todd's recent review of the group of Ant Thrushes to which 

 this bird belongs, there is still much doubt as to the number of forms that 

 should be recognized. Chapman in his Distribution of Bird Life in Colom- 

 bia, p. 370, says that the small race from the Pacific Coast of Ecuador and 

 another from the western slope of the Central Andes in Colombia, are 

 both good and as yet unnamed. 



Our bird is not large, like Peruvian examples from the general region 

 whence came the type of D. tambillanus Tacz. nor is it small as are west 

 Ecuador skins, but affords the following measurements: wing, 66; tail, 

 41; tarsus, 20; culmen, 15, which are about those of Colombian speci- 

 mens. 



Hapalocercus meloryphus fulviceps (Scl.). One adult 9, Perico, 

 September 11. 



Ridgway considers that Hapalocercus belongs in the Formicariidse and 

 we follow him in this disposition of the genus. 



Grallaria albiloris Tacz. One adult female, Tabaconas, September 2. 



The only representative of the genus observed throughout the entire 

 trip was the specimen collected. It was found while scratching among 

 the wet mosses of the forest floor near Tabaconas. 



Furnariidae. 



Geositta peruviana paytse Menegaux and Hellmayr. Five adults, 

 Paita, July. 



These are topotypes. Whether or not this much paler bird should stand 

 as a species, as the original describers considered it, or as a subspecies of 

 G. peruviana Lafr., is of course a matter of opinion. 



The Miner was the commonest bird about Paita. Flocks of them were
