Editorial. 7 



A List of the Vascular Flora of Allegheny County, prepared by Dr. 

 J. A. Shafer, supplemented by O. E. Jennings. 



Lists of the Fungi, Birds, Mammals, Fishes, and Mollusca are being 

 prepared, and the remaining orders of Insects, as well as the Crus- 

 tacea, Arachnida, and Myriapoda are being collected and studied 

 with a view to the enumeration of the species which occur in the 

 ''back parts of the Colony of Pennsylvania," as the denizens of 

 Philadelphia were in the habit a hundred years ago of naming the 

 region.
