rather pruinose on the head and back. One of these specimens in 

 the molt is proved to be an old bird, while other undoubted old 

 birds have the more tawny plumage, so that I am not sure whether 

 this slightly different coloration represents a bird of any particular 

 age or is merely an individual variation. 



Thryothorus ludovicianus (Lath.). Carolina Wren. 



The molts and plumages of this bird are exactly parallel to those 

 oi Harporhynclms rnfxis aud, so far as I can ascertain, there is no 

 spring molt. The feathers of the crown are much abraded in all 

 spring birds, and in late summer the abrasion of the entire plumage 

 is extreme. 



Troglodytes aedon Vieill. House Wren. 



Plumages, first, winter, nuptial. 



There is no spring molt in the House Wren and the contrast be- 

 tween spring and fall specimens, caused by abrasion, is striking. 



Troglodytes hiemalis Yieill. Winter AVren. 



Plumages and molt exactly as in the House Wren. 

 Cistothorus stellaris (Licht.). Short-billed Marsh Wren. 



Plumages, first, Avinter, nuptial. 



There is a complete spring molt of the body feathers in this 

 bird as shown in a series taken at Tarpon Springs, Fla., April 15th. 

 They become very much abraded by July. 



Cistothorus palustris (Wils.). Long-billed Marsh Wren. 



Molts as in the preceding.* 



Family PARID^. 



Sitta carolinensis Lath. White-breasted Nuthatch. 



Plumages, first, winter, nuptial. 



There is no spring molt, and, excepting on the flight feathers, 

 abrasion is not very apparent until after the breeding season. 



Sitta canadensis Linn. Red-bellied Nuthatch. 

 Molt as in the preceding. 



Parus bicolor Linn. Tufted Titmouse. 



Plumages, first, winter, nuptial. 



No spring molt, and but little eflfect produced by abrasion. 



Parus atricapillus Linn. Black-capped Chickadee. 

 Parus carolinensis Aud. Carolina Chickadee. 



Molt as in the preceding, all plumages very similar to each other. 

 * Cerihia apparently molts exactly as in Troglodytes aedon.
