Pteroglossus Sturmit, Natt.in Imp. Mus. of Vienna.—Sturm’s Edit. of Gould’s Mon. of Ramph.,

Tue solitary example of this fine species contained in the Imperial Museum at Vienna ts 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 flyin
proved to be a fine male in the adult dress, and, after his return to Europe, was named by him Prerog/ossus

g in the primitive forests at Borba near the mouth of the Rio Madeira. It
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 itor quads 10 having the uueten mandible entirely
black, instead of black with a white base; in having a dark brown iris iad of oan with a black spot on
each side near its inner margin; in the orbits being dark blue grey, with a border a dull carmine-red nea
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 pic oe ae a pa
in the male P. detorguatus, and which is narrower and of a brighter ee in the female o et 1e
reasons which induced M. Natterer to regard this bird, of which it 1s true he had only received i single
specimen, as distinct, was the circumstance of its being a fully adult bird, ae - ee e oe
other species, as the Preroglossi maculirostris, Gouldi, Natterert, Langsdorffi, Reinwardti, the specific
distinctions reside almost exclusively in the beak.”
The figure is of the size of life.
