Mr. O. Salvin^s Synopsis 
I have compared specimens from all the localities above 
mentioned, and find little or no variation in individuals from 
most distant points of the range of the species. The yellow 
colour of the under surface is quite uniform, one of the cha¬ 
racters by which its northern representative may be recog¬ 
nized— 8. aurantiaca having the belly of an orange- instead 
of a lemon-colour, the tint of this part in 8. verticalis.

This well-marked species was first discovered by Tschudi 
in Peru, where it has since been found by Jelski at Chilpes 
and Punamarca, and by Whitely at Khachupata. Its range 
also extends into Bolivia, where Mr. Buckley found it and 
j sent us specimens from Simacu.
