of the river. It is very terrestrial in its habits, rarely rising 

 above the lowest branches of the trees, and preferring to seek for 

 insects and larvse among the dead leaves and twigs which strew 

 the ground in such situations, and where opportunities for ob- 

 serving them but seldom occur, as in the presence of man they 

 are shy and quiet. I never met with them after the end of 

 August. 



Geothlypis teichas (Linn.) Maryland Yellow-th') oat— This 

 handsome little warbler is a summer visitor to the open districts, 

 wherever there is a sufficient growth of weeds and low stunted 

 bushes to affi)rd it the shelter and concealment which it needs. 

 They are most abundant during the spring and fall, especiall}^ in 

 September, when almost every patch of weeds holds its family 

 party, but a few pairs certainly remain to breed, resorting for 

 that purpose to the edges of dry watercourses, especially in rich 

 land. The only nest which I found was placed among tangled 

 roots of weeds, about a foot from the ground, and was, unfortu- 

 nately, torn down and destroyed by some prowling animal, after 

 the deposition of one egg. It was composed externally of dry 

 sedge and weeds, and rather sparsely lined with fine grasses. 

 The stomachs of those which I examined were filled with insect 

 remains, among which the brilliant green elytra of small beetles 

 were always conspicuous. They generally keep near the ground, 

 seldom indeed rising above the summits of the weeds, unless close 

 pressed. 



Myiodioctes mitratus (Gmel.) Hooded Warbler. — I only 

 obtained two specimens of this bird, both of which occurred 

 during the latter part of August. It is, however, probable that 

 they are regular summer visitors to the dense and impenetrable 

 jungles of green brier in the river bottom, in the recesses of 

 which they escape observation. The two procured were very 

 tame, flitting before me down roads cut through the thicket, and 

 perching only on boughs near the ground. 



Myiodioctes pusillus (Wils.) Black-capped Yellow Warbler. 

 — This species occurs in our district at the periods of migration, 

 passing northwards in small numbers during May, when they 

 frequent the weed beds on neglected farms, but, on their return 

 in September, they principally resort to the creeks and open 

 woods, wandering about in small family parties along with
