(See vol v., p. 344.) 



Common in tbe few suitable localities around San Jose, Miraflores, 

 and cafions of tbe Miraflores and Santiago Peaks. At Agua Caliente 

 a pair were noticed feeding their young just out of tbe nest May 7. Tbe 

 only note traced to tbis species was a loud chip. I listened long, wben 

 in tbe neigbborbood of one or more of tbese birds, for tbe familiar song 

 ■of the Maryland Yellow-throat {G. triclias), but failed to hear it. Their 

 habits are quite like those of G. trichas, and the eggs are not materially 

 <liflerent, if a nest found by my guide on tbe Miraflores andTodos San- 

 tos trail May 6 belonged to this species, as I supposed it did, having 

 seen a fine male near tbe spot from which it was taken. 



4. Lanivireo solitarius cassini (Xantus). 

 Found breeding; common at Miraflores.

Only four individuals seen. A nest found April 29 contained eight 

 eggs. It was fastened to upright reeds, and was composed of coarse

*I was iuforuied several years siuce, by Sr. Don Jos6 C. Zeledon, otSau Jos^, Costa 

 Rica, that he has found uests of this species m Costa Rica, which were lined with 

 green leaves of the»leuiou tree. It would he an interesting fact shoukl this prove to 

 be a regular habit of the species. — R. R.
