" Adult male ( type of species): Above dark leaden grey, the ear coverts and sides of the neck uniform with the crown, which is slightly darker than the back, as also are the wing- coverts; upper tail- coverts tipped with clear ashy- grey; quills brown, with rufous brown shafts, the secondaries leaden grey like the back; the quills barred with darker brown, these bars showing more plainly underneath, where the lower surface of the wing is ashy white, inclining to pure white near the base of inner web ; tail black, tipped with whitish and crossed with three narrow bars of clear ashy grey, a little rufescent near the shafts; entire under surface, including the under tail- currents, pale grey, the throat and under wing- coverts whiter, the shafts darker, showing a hair- like stripe. Total length 17 inches, culmen 0.85, wing 9.8, tail 7.8, tarsus 2.15, middle toe 1.4. ( 3/ M*. Lugd. f-( SHARPE, I c.) Regarding this very rare species, of which we have seen no examples, Mr. Gurney writes me as follows:- u This species, which Schlegel calls a * Ni8U8f and Gray a * Cooperastur\ seemed to me, when I examined it at Ley den in 1869, to be a Leucopternis. At first sight its appearance is a good deal like Micrastur mirandolleiy* but from that species it is evidently generically distinct. The type- specimen at Leyden is the only one I have seen. The bird figured by Temininck as the young of this species is said by Schlegel to be the young of Cooperastur pileatm? { Vide Mus. Pays- Bas, Astures, p. 43.) t NISUS(!) PECTORALIS.

" Female, not quite adult- Above brown, with tips of rather paler brown to the feathers of the middle back, scapulars, and secondaries; the greater part of the wing- coverts, the interscapular region, and the lower back, rump, and upper tail- coverts black, with white tips; crown of head crested, pure black; ear- coverts and sides of neck rich rufous, forming a broad collar round the back of the latter; feathers below the eye and a faintly- indicated moustachial streak black; throat white, a * This resemblance is so very close that we have seen specimens of the Micrastur labeled " M. poliogaster Temm." t Notwithstanding Professor Schlegel's conclusion, we judge from TemmiucVs plate that the bird figured is really the young of X. poliogaster, since it agrees with this species in its stout form, and presents conspicuous points of difference both in form and coloration from the yonugof X. pileatus. |
