Pteroglossus Sturmii, Natt. in Imp. Mus. of V ienna.—Sturm’s Edit, of Gould’s Mon. of Ramph., 
pi. 
The solitary example of this fine species contained in the Imperial Museum at Vienna is the only one that 
has yet been sent to Europe. It was brought down by the late Mr. John Natterer, on the 22nd of January, 
1830, out of a small flock flying in the primitive forests at Borba near the mouth of the Rio Madeira. It 
proved to be a fine male in the adult dress, and, after his return to Europe, was named by him Pteroglossus 
Sturmii, in honour of one or other of the brothers Sturm of Nuremberg, who have included a figure and 
description of it in their translation of the first edition of this work. As I have never seen the bird myself 
I have been obliged to copy their figure, and it is only fair to them to give their remarks upon its alliance, 
and the differences by which it is distinguished. 
“This species differs from the very similar Pteroglossus Utorquatus in having the under mandible entirely 
black, instead of black with a white base; in having a dark brown iris instead of orange with a black spot on 
each side near its inner margin ; in the orbits being dark blue grey, with a border of dull carmine-red near 
the feathers of the crown instead of the eye-rings being grey, and the remainder of the orbits beautifully 
mingled carmine and vermilion ; and in the pale yellow crescentic mark on the breast, which does not exist 
in the male P. bitorquatus, and which is narrower and of a brighter yellow in the female of that species. The 
reasons which induced M. Natterer to regard this bird, of which it is true he had only received a single 
specimen, as distinct, was the circumstance of its being a fnlly adult bird, and that in the case of several 
other species, as the Pteroglossi maculirostris, Gouhli, Nattereri , Langsdorjfi, Reinwardti, the specific 
distinctions reside almost exclusively in the beak.” 
The figure is of the size of life.
