As -will be apparent by our figure, tbe Accipiter castanilius is one o f tbe most stx-ongly
marked species o f tbe numerous genus to wbicb it belongs, being readily recognizable, iu its
adidt stage at least, by its deep chesnut flanks and broadly banded under-plumage. It is
surprismg tbat so noticeable a species should have remained unkno-wn so long, but, as far as we
can make out, tbe first specimens o f it received in Europe were those obtained by M. Verreaux’s
collector, in the -vicinity o f S. Martba, about tbe year 1852, upon which Prince Bonaparte’s
description was founded. It is probable tbat, like many other birds, this Sparrow-hawk has a
very limited range, and is confined to tbe lower valley o f tbe Magdalena,—a country in which
few collections have been foimed. I f it ascended far up the valley it would come within tbe
grasp o f tbe diligent bird-bunters of Bogota, which does not appear to have been the case.
The Cbcsnufrsided Span-ow-bawk is of about tbe same size as Accipiter eollaris, Sclater,
and is more nearly allied to tbat bnd than to any other American Sparrow-hawk, having tbe
same robust tarsi and short toes. A . collaris is, however, a very distmct species, as reference to
tbe plate and description o f tbat bird in tbe “ Ibis”* w ill shew.
Oiu' figui-e o f tliis species is taken fi-om a specimen in tlie British Museum, which was
purcliased o f M. Verreaux. Tbe bnd is decidedly very rare, and we do not recollect to have
seen it in any other collection.
