The first specimens of this Synallaxis sent to Europe were doubtless those that 
came into Prince Bonaparte’s hands from Col. Velasquez, who obtained them in 
Guatemala’. They were then supposed to belong to S. cinerascens, Temm., a species 
of South Brazil, but quite a different bird. Mr. Sclater’s description was based upon 
a specimen in the Derby Museum in Liverpool, obtained by Delattre (probably in 1846) 
near Coban in Guatemala; other examples being in the British Museum and in his 
own collection. In 1851 Strickland received a specimen from Guatemala !!; the bird 
was afterwards traced to the State of Vera Cruz by Sallé #3 and Boucard 4, and is now 
known, as Sumichrast says, to be not uncommon in the hot low-lying portions of that 
State as far north as the town of Vera Cruz, where Godman found it in February 1888. 
Southwards of Vera Cruz it is common, and probably spreads over the whole ot 
Yucatan, the State of Tabasco, British Honduras, and Guatemala, to the neighbourhood 
of the town of Coban, and to Yzabal on the Golfo Dulce 8. On the side of the moun- 
tains sloping to the Pacific Ocean, §. erythrothorax is common about Escuintla and — 
Retalhuleu, but we have not traced it so far as the State of Chiapas in this direction. 
Returning to the Atlantic seaboard, the most southern record we have is that of
