FEMALE CCERULEAN WARBLER.

short and imperfect account of the species. It is by no means 
more common at this time, than it was when he wrote ; which 
may account for the difficulty of ascertaining the period of its 
migrations, and for the circumstance of our having never met 
with the nest, and our want of acquaintance with its habits. 
We can only add to its history, that it is found in the trans- 
Mississippian territory; for the Sylvia hifasciata oi Say, accu- 
rately described in Long’s first expedition, is no other than the 
male. We have examined the specimen shot at Engineer 
Cantonment. 
Although the undisputed merit of first making known this 
species belongs to Wilson, yet the scientific name that he ap- 
plied to it cannot be 'retained, inasmuch as it is pre-occupied 
by the blue-grey warbler, a Linnean species, which Wilson 
placed in Muscicapa, but which we consider a Sylvia^ notwith- 
standing that it does in some degree aberrate from the typical 
species of that genus.* Under such circumstances, we cannot 
hesitate in adopting the name substituted by Mr Stephens, the 
continuator of Shaw’s compilation.
