A t tlie time wlien our notes on the genus Asturina published in the Zoological Society’s
“ Proceedings” for 1869 were written, we were not perfectly certain whether Schlcgel’s Asturina
gularis in the Leyden Museum was referable to the present bird. Soon afterwards, our
artist, Mr. Smit, being in Leyden, we requested him to make a coloured drawing o f Schlegel’s
type-specimen, which, hy tho .kindness o f tho authorities o f that celebrated institution, he was
permitted to do. Upon his return to this country with the drawing we had no difficulty in
recognizing in it the adult dress o f Asturina pucherani
Of the three other species belonging to the present section this Asturina appears to resemble
most nearly the northern A. ruficauda, having the tail-bands rufous instead o f pale cinereous.
But it is immediately distinguishable in tbe adult dress by its dark throat (from which, no doubt,
Lichtensteui derived his name gularis), and b y the pale ochraceous colouring o f the lower
surface.
There is a single adult specimen o f this Hawk in the Gallery o f the British Museum said
to have been received from Bolivia.
Our principal figure o f this species is copied from the drawing already spoken of, which
was made by Mr. Smit from the typical specimen o f Asturina gularis in the Leyden Museum
and represents it at two-tliirds o f the natural size. The figure in the hack-ground is taken from
the typical specimen o f Asturina pucherani in the Norwich iluseum, which has been kindly lent
to us for this purpose.
