Thryothorus castaneus Lawrence

Thryothorus castaneus Lawrence, 1861b: 321 (Atlantic Slope, Panama Railroad).

Now Thryothorus nigricapillus castaneus Lawrence, 1861 . See Wetmore et al., 1984: 88, and Brewer and MacKay, 2001: 149.

SYNTYPES: AMNH 39458, adult male, and AMNH 39459, adult female, collected on the Atlantic slope of the old Panama Railroad, Isthmus of Panama, Panama, by James McLeannan and John R. Galbraith. From the George N. Lawrence Collection.

COMMENTS: The above syntypes are the only two specimens of this taxon that came to AMNH and both are marked ‘‘type’’ in Lawrence’s hand. Lawrence (1861b: 322) noted that he had identified this form as Thryothorus nigricapillus in the first part of his list ( Lawrence, 1861a: 293), based on a collection made by McLeannan alone. He, in fact, listed Thryothorus nigricapillus ? without description or comment. If he had a specimen at that time, it did not come to AMNH with the Lawrence Collection.
