Remarks. — The geographic ranges of the two races of the 

 Tufted Titmouse are the same as those of the Brown-headed

 intergrades with true bicolor in southeastern Georgia. Like the 

 Nuthatch, it is not a very common bird.

 several places, Bermuda, Maryland, etc., we must of course as- 

 sume that the bird he figured came from southern South Caro- 

 lina.* The birds of this region, as also those that breed in east- 



' These blues are hard to define exactly owing to the sheen of the feathers, 

 and to the varying shades of the color when the skin is turned in different 

 lights.

* It is evident that Linnaeus took his description wholly from Catesby's 

 plate, perpetuating the error of coloring of Catesby's figure, in his discription.
