78 BANGS — SOME COLOMBIAN BIRDS Ee 
under A. mu/santi,' that I suspect may belong in reality to A. 
astreans. 
Amazilia warszeweizi (Cab. & Heine). 
One adult male, San Sebastian, July 9. 
Antrostomus rufus (Bodd.). 
One female from San Sebastian, July 15. 
Sayornis cineracea (Lafr.). 
One adult female from San Sebastian. 
Myiotheretes striaticollis Scl. 
One male from E] Mamon. 
Elznia pagana (Licht.). 
One adult male from El Mamon. 
Elznia browni Bangs. 
Forty-one specimens, adults of both sexes and one male in 
nestling plumage, from San Sebastian and E] Mamon. 
The distribution of the two closely related species, #. drownz and 
E. sororia, of the Sierra Nevada de Santa Marta is quite inter- 
esting. 4. drowni occurs at much higher altitudes than Z. sororza, 
Mr. Brown having taken it at 12,000 feet (El Paramo de Maco- 
tama). The highest he has found &. sorvoria is 7000 feet (one 
example from Chirua). At many stations they occur together. 
At La Concepcion, 3000' feet, Mr. Brown took a series of forty 
odd examples of £. sororia and only four of £. drownz, from thence 
upwards sororta becomes rarer and rarer, until 7000 feet altitude 
is reached, where it ceases altogether and above which £. browni 
occurs alone.
