superciliaries it is more like B. holivianus. It differs from both in 

 havin<r the gray of the pileiim with a brond dark lateral border, and 

 is unquestionably specifically distinct. Although Wied described tRis 

 bird in 1821, his types being still extant in the American Museum of 

 Natural History, his name has until very recently been passed over 

 in favor of Lichtenstein's later appellation of stragvlatus^ possibly 

 because he (Wied) fails to mention the distinctive character of the 

 lateral crown-stripes, or else because it was supposed his description 

 did not appear until 1831. He is the only author to give an extended 

 account of its habits, as observed in the southern part of the State of 

 Bahia. Later authors have met with it as far south as Rio Grande 

 do Sul. The Paraguay record by Bertoni, above cited, requires con- 

 firmation. Nowhere, so far as known, does its range meet that of 

 B. Tnesoleucus, being strictly confined to the coast States of Brazil 

 from Bahia southward. It has the habits of a water thrush, be- 

 traying thus its affinity to the members of the genus Phaeothlypis.
