(media) being utterly insufficient for the recognition of the 
species, as Schlegel's assignment of them proves (Mus. d. 
P.-B. Ralli , p. 37). 
I also saw in the gallery of the Philadelphia Academy an 
unnamed and unlabelled specimen of Accipiter pect oralis , Bp. 
(Astur pectoralis, Sharpe, Cat. Birds, B. M. i. p. 121, 1874). 
Of this scarce bird, the only specimens known to exist, be¬ 
sides the one now referred to, are one in the Antwerp Mu¬ 
seum (Bonaparte's type) and two in the Derby Museum at 
Liverpool (Cf. Sclater, Ibis, 1861, p. 314). Besides these, 
Natterer obtained three specimens at Ypanema and Borba, in 
Brazil (Pelz. Orn. Bras. p. 6), one of which passed in 1862 to 
the Leyden Museum (Schl. Mus. des P.-B. Astures, p. 18). 
Seven specimens in all. 
There is a specimen in the same museum of Accipiter col- 
laris , Scl., from Bogota, a bird still rarer than the last named. 
Only three specimens appear to exist in collections—the type 
in the British Museum, one in the Norwich Museum, and the 
one now mentioned as being in Philadelphia.

Through Dr. T. M. Brewer's kindness I was enabled to ex¬ 
amine the fine series of birds in this museum, celebrated as 
containing the collection formed by the late Baron de La 
Fresnaye, and including most of the types of the many species 
described by that author. 
Previous to the sale of the Lafresnaye collection a catalogue 
of the species it contained was prepared by the late M. J. 
Yerreaux. This work was somewhat hurriedly executed; and 
the names were taken, in most instances, from the specimens 
without being checked by reference to Lafresnaye's papers. 
A very considerable number of the names mentioned in this 
catalogue are only MS. titles, descriptions of which have never 
been published; but they have been placed on the specimens in 
the galleries, which have been named from Yerreaux's cata¬ 
logue. It would be of great value to ornithological science 
if some competent ornithologist would undertake the verifi¬ 
cation of the names of this collection with the published
