is observable in nests. Most nests are rather 

 compactly built. A heterogeneous medley of fine 

 and coarse grasses, skeletonized leaves, fragments 

 of corn leaves and husks, are conspicuous ex- 

 teriorly; while interiorly, there is a thick lining of 

 slender dichotomously-divided branches of Pani- 

 ctiin capillare. The dimensions vary but slightly 

 from what has been recorded by others. 



A single specimen which we have by us, in 

 details of structure and elements of composition, 

 bear a close resemHance to a published descrip- 

 tion of the Turdus Pallasii of Cabanis. This nest 

 is loosely constructed. The situation in which it 

 was found, ta wit, a tussock of grasses would seem 

 to render a more durable fabric unnecessary. 

 Exteriorly it is composed of the leaves and culms 

 of coarse grasses, fragnients of corn husks and 

 leaves of the same, dried leaves of Quercus, Fagus 

 and Castanea. in abundance, inner bark of various 

 trees, besides a species of moss probably Sphag- 

 num squarrosum. The interior is constituted of 

 fine leaves, slender stems of Panicum, and a 

 superabundance of slender dark rootlets of Aris- 

 tolochia serpentina or N\r^\xv\2L-?,r\sik.^roo%. In situ, 

 the dimensions of the fabric vary a trifle from the 

 typical form. 



The period of incubation of this species, owing 

 to its various and secluded habits, we have not 

 been able to determine. 



The eggs, usually four in number, seldom more, 

 are of a uniform green color, slightly tinged with
