"On the Truando, in January, and at Turbo early in April, 1858. In small 

 flocks of ten or twelve, in the high trees, very much as in autumn in the 

 United States." (Mr. W. S. Wood, Jr.) 



106. Thryothorus nigricapillus, Sclater. 



Thryothorus nigricapillus, Sclater, Proc. Zool. Soc. London, 1860, p. 84. 



From the River Truando. 



Two specimens appear to be this species, or at least very closely allied. 

 They differ only in having the throat transversely banded with black lines, 

 same as on other parts. 



" In low bushes and on the ground, on the banks of the Rio Truando, in 

 the Cordilleras. Frequently seen, and runs on the ground, more than usual in 

 the larger Wrens of the United States, but has similar sreneral habits." (Mr. 

 W. S. Wood, Jr.) 



107. Thryothorus. 



A large plain colored species, for which I have found no name, but am not 

 sufficiently acquainted with the group of Troglodytince to feel warranted in 

 proposing a species. Several specimens from Turbo and Carthagena. 



108. Sclerurus brunnecs, Sclater. 



Sclerurus brunneus, Sclat. Proc. Zool. Soc. London, 1857, p. 17. 



From the river Ingador. 



One specimen only in the collection of the Expedition appears to be this 

 species. "On the banks of a small stream called the Ingador, near the coast 

 of the Pacific Ocean. In the Palm trees, clinging to the leaves and searching 

 for insects. March, 1858." (Mr. W. S. Wood, Jr.)

From the river Truando. 



" These kinds of birds were very abundant on the trees in the Cordilleras, 

 and a few were seen at camp Toucey, on the Rio Truando, within 20 or 30 

 miles of the mountains. They run on the trunks and branches very rapidly, 

 and appear to be very greedy and rapacious. Not shy, and easily approached, 

 but not easily shot, on account of their quick movements. When they have 

 ascended a tree, they fly down to the base of another, like the Brown Creeper 

 of the United States, (Certhia)." (Mr. W. S. Wood, Jr.)
