hood. I formation respecting their habits, notes, and nest, is 
wanting to complete the history of the species. 
Regulus cristatus, (Golden-crested Wren.) Does this spe- 
cies ever pass the summer in any of the northern States, or 
mountainous districts ? 
Regulus Cuvieri, (Black-banded Ruby-crowned Wren.) This 
species, first given by Audubon, is readily distinguishable by the 
vermillion crown being bordered with a band of black. Has this 
species ever been seen in the northern and middle States ? 
Troglodytes europeus, (Winter Wren.) The nest of this 
species, and the region in which it breeds, are yet unknown in 
America. It is supposed to be the common Wren of Europe. 
Sylvia coronata, (Yellow-rump Warbler, or Myrtle Bird.) 
As this species appears in this vicinity by the close of August, 
we might suppose it to breed and pass the summer at no great 
distance to the north. ‘The nest and manners, in the season of 
incubation, are unknown. 
Sylvia icterocephala (Chesnut-sided Yellow-crowned Warb- 
ler.) This bird, no doubt, breeds in the mountainous parts of 
Massachusetts. An occasional pair, I have reason to believe, 
pass the summer in the vicinity of the Blue Hills of Milton. As 
yet, however, the nest, eggs, and circumstances of incubation are 
unknown. Late in the month of May, I have heard this bird 
singing, in a tone and manner very similar to those of the common 
summer Yellow-Bird, (Sylvia estiva.) 
Sylvia varia, (Black and White Creeper.) A nest of this 
species, on the ground, was shown to me in Roxbury last summer 
by Mr. Newman of Cold-Spring Place. Is the nest uniformly on 
the ground, or is it not occasionally in hollow trees? as, like a 
Woodpecker, the bird passes most of its time on their trunks in 
quest of insects. What are the color and markings of the eggs ?
