1902] Elliott The Parula Warbler. 95 



states that not one of the features he has used in separating the 

 two forms is quite constant. Bearing" this in mind, I have little 

 hesitation in arranging the series as follows. 



1. C. americana usnece, ad. $. Coll. W. E. S. London, May 

 1881. 



2. C. americana iisnece, ad. S . Coll. W. E. S., Komoka, 24th 

 May, 1888. 



3. C. americana usnece, ad. $ . Coll. W. E. S., Komoka, 6th 

 May, 1893. 



4. C. americana usnecB, ad. $ . R. E., Plover Mills, i6th May, 

 1899. 



The first two being typical of the new Northern Parula, the 

 last two being not quite typical of the original species now known 

 as the Southern Parula. 



The breeding range of the Northern Parula is given as " New 

 England, New York and westward along the northern tier of 

 States, northward to the Maritime Provinces and Canada." That 

 of the Southern Parula, " The South Atlantic and Gulf States east 

 of Texas, northward near the Atlantic Coast to the District of 

 Columbia and in the interior to Mt. Carmel, III." 



With respect to the last named, Mr. Brewester had examined 

 no summer birds from immediately north of Washington or Illi- 

 nois, and, while doubtless the vast majority of the Parulas of On- 

 tario will prove to belong to the northern sub-species, yet the 

 extreme southern edge of the Province being in the same faunal 

 zone as Illinois, the Southern Parula may prove to be a not rare 

 summer visitor to the counties bordering on Lake Erie. 



I would urge on the members of our C)rnithological Section 

 the desirability of collecting more specimens, especially of adult 

 males taken in spring. It is needless to add that accurate measure- 

 ments made in the flesh are of great value to any one attempting 

 the classification of such closely related forms.
