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.

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 PhiladeliDliia. P. grana- 

 clensis 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. Lawa'ence. 



Professor Orton kindly presented me with a specimen of 

 the bird described by Cassin as Icterus grace-annce (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 /. 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 Cijanocorax mystacalis, collected 

 by Professor Orton at Machala, near Guayaquil, Ecuador.
