The locality "Pirris" given by both Messrs. Ridgway and Cherrie for 

 the specimen taken by J. Cooper, and which Cherrie described (Ridgway 

 MS.) as Vireo superciliaris, is undoubtedly an error, and should be 

 Birris de Cartago. Cooper never collected at Pirris, or Pozo Azul de 

 Pirris, as it is commonly known, but did collect at Birris. It is out of the 

 question to think of getting Vireo carmioli at Pozo Azul, which is only a 

 short distance above sea-level, for this bird is found only in the higher 

 mountains, probably not occurring below 6,000 feet (except very spar- 

 ingly), and certainly most commonly at about 8,000 to 9,000 feet on the 

 volcanoes. It is an inhabitant of the heavy forest, being found rather 

 low down among the undergrowth and low limbs of the trees, as is usual 



with vireos.

This is one of the extremely rare birds of Central America. It was 

 discovered by O. Salvin and Capt. J. M. Dow at Puntarenas, Costa Rica, 

 in 1862, where a single specimen was secured in the mangroves opposite 

 the town on the mainland. Another specimen was taken shortly after by 

 Salvin and Dow at Realejo, Nicaragua, not far from Puntarenas, which 

 is now in the collection of the U. S. National Museum. The bird re-
