DESCRIPTIONS 
OF 
TWO NEW SPECIES OF SYNALAXIS 
BY 
T. C. EYTON, Esa., F.L.S. &e. 

SYNALLAXIS OLIVACENS, Eyton. 
§. dorso subtusque olivaceis, vertice nuchaque tectricibus alarum 
caudaque laté castaneis; rectricibus alarum pogoniis externis cas- 
taneis brunneo prepillatis, linea perocculari atra, gula jugulo pec- 
toreque superiore cinereis singulis pennis albo marginatis. 
Long. corp 6 in.; ros. fron. 4 in. ; tarsi 10 lin. 
Both the specimens I possess of this beautiful species of Synal- 
laxis were received from South America, but I am not aware of 
the exact locality. 
SYNALLAXIS MODESTUS, Eyton. 
S. corpore toto alisque brunneis, gulé macula castaneo-aurantiaca, 
caud& rectricibus quatuoribus externis pogoniis exterioribus cas- 
taneis. 
Long. corp 6} in.; ros. fron. 4 in.; tarsi 11 lin. 
I am not certain from whence the above bird came into my 
hands, but believe it was from Bolivia. In one specimen the spot 
on the throat is much lighter than in the other; there is also a 
slight tinge of castanous on the under tail-coverts of the specimen, 
with the darkest throat, which is probably the male.
