for drinking and bathing by fountains and open pools. It is most im- 

 portant, however, to provide food. This can be done artificially, 

 particularly in winter, by feeding boxes and similar devices, but the 

 most permanent and practical plan is to plant various seed and fruit 

 producing trees and shrubs. Among the latter, alders, birches, larches, 

 pines, junipers, bayberries, hollies, and similar trees are among the most 

 satisfactory. The trees bearing fruits attractive to birds are here 

 tabulated in a manner to show graphically the duration of the fruit 

 season ; and those that are desirable to plant as a protection to cultivated 

 varieties which might be molested by the birds are separately indicated.

This paper contains tables of migration dates for both spring and fall 

 from localities in the United States, Canada, and Alaska, illustrating 

 the migratory movements of Bomhycilla garrula, Bmnbycilla cedrorum, 

 and Phainopepla nitens. All of these species, Bomhycilla cedrorum 

 particularly, are more or less irregular and erratic in their movements.

The generic name Orchilus Cabanis, proposed for a genus of South 

 American Tyrannidae, has commonly had assigned for its type Platy- 

 rhynchus auricularis Vieillot. Its type is, however, really Orchilus 

 pileatus Cabanis, which, since furthermore it is preoccupied by Orchilus 

 Morris, makes it a synonym of Lophotriccus Berlepsch. This leaves the 

 present genus Orchilus without a name, because Perissotriccus Ober- 

 holser, proposed for Orchilus ecaudatus Lafresnaye, is generically distinct 

 from the other species commonly referred to Orchilus. This being the 

 case, the new generic name Notorchilus is here proposed, with Platy- 

 rhynchus auricularis Vieillot for its type. H. C. O.
