typical specimens of that species from Bolivia. The Bolivian 
bird is pale yellowish where the other is white, the black edges 
of the feathers are much narrower, and the upper plumage, 
especially the head, is brighter rufous; the bill, too, is much 
smaller. The Bogota bird should bear the name Margarornis 
perlata , Less. Echo du Monde Savant, 1844, p. 275, based on 
a bird from Columbia. 
Picumnus granadensis, Lafr. Rev. Zool. 1847, p. 78. 
The specimen thus named is undoubtedly the young of the 
bird called P. olivaceus , Lafr., in the same collection. The 
latter is not Lafresnaye's type, as the species was described 
from a specimen in the Massena collection (Cf. Rev. Zool. 
1845, p. 7), and should therefore exist in the Museum of the 
Academy of Natural Sciences in Philadelphia. P. grana¬ 
densis was obtained from Cali, in the upper waters of the 
Cauca; P. olivaceus came originally from Bogota. 
Museum at Vassar College , Poughkeepsie , N. Y. 
On my way to Niagara I stayed some hours at Vassar Col¬ 
lege, Poughkeepsie, in order to see the collection in charge 
of Professor Orton, many of the specimens in which were 
collected by him during his rambles in tropical America, 
and some of them have, at various times, been described by 
Mr. Lawrence. 
Professor Orton kindly presented me with a specimen of 
the bird described by Cassin as Icterus grace-anna (Pr. Ac. 
Phil. 1867, p. 52), collected by himself at Machala, near 
Guayaquil. The species appears to be a very distinct one, 
the white mark on the wings recalling I. pectoralis, the spots 
on the breast being absent. The yellow colour, however, is not 
so deep in tint. The patria of the skins described by Cassin 
was not satisfactorily determined. This point is cleared up 
by Professor Orton^s skins. The bird would appear to 
be restricted in its range to Western Ecuador and Western 
Peru. 
I also saw a specimen of Cyanocorax mystacalis , collected 
by Professor Orton at Machala, near Guayaquil, Ecuador.
