C. gyroloidi (Lafr.) similis, sed differt capite magis rufes- 
cente, nucha flavescente absque torque distincta, et prseser- 
tim campteriis rufo-castaneis nec aureis; a C. gyrola dorso 
posteriore cseruleo et campteriorum colore, a C. desmaresti 
iisdem characteribus et gastraeo cseruleo discrepat; cum 
C. lavinia, Cassin, colore campteriorum convenit, sed tectri- 
cibus alarum et remigibus viridibus et gastraeo caeruleo di¬ 
ver sa. 
Head, cheeks, and chin rufous chestnut, upper surface 
generally green; neck yellowish green, but without a distinct 
collar; shoulders bright reddish chestnut; rump and under 
surface blue; under tail-coverts green; thighs pale reddish. 
The bright reddish chestnut colour of the shoulders distin¬ 
guishes this bird from all known species of the gyrola group, 
with the exception of C. lavinia ; but the latter differs in 
having the wing-coverts and outer edges of the secondary and 
shorter primary quills rufous, and the undersurface green, 
with exception of a longitudinal stripe of pale blue on the 
throat and another on the middle of the abdomen. 
During a recent visit of Herr Taczanowski to Vienna, when I 
showed him Natterer's collection of birds' skins, he pointed 
out the difference of this red-shouldered bird from the indi¬ 
viduals of C. gyroloides , under which name it had been pre¬ 
viously comprised.
