afterwards by Dr. Merrill at Fort Brown. 
Myiarchus erythrocercus, Scl. & Salv. This species, also 
new to our fauna, has been taken by Dr. Merrill, who has 
also been so fortunate as to secure two sets of its eggs, one 
with five, the other with three examples. These, as might 
be supposed, are very similar in all their peculiarities to those 
of M. crinituSj M. meooicanus, and M. cooperi, most nearly 
approaching the latter in the size and number of its purplish 
brown markings. A full account of these will be given in 
Dr. MerrilFs forthcoming ‘ List of the Birds of the Lower 
Bio Grande,^ to be published by the Smithsonian Insti¬ 
tution. He already has a list of 250 species that he has 
himself taken. 
Dr. Merrill has also secured the birds, with their nest and 
eggs, of what Mr. Bidgway calls Peuceea (Bstwalis, variety 
arizonce, I am not much impressed, generally, with this 
variety style; and in the present case I have no faith in 
it whatever. The set of eggs, taken with their parents, in 
this ease are as widely different from well identified eggs of 
the genuine P. cestwalis as nearly spherical, decidedly blue 
eggs can be from pointedly oval crystalline white eggs. I 
therefore believe P. arizonce to be a good species, and cer¬ 
tainly not a variety of P. cBstivalis. I believe it is not new to 
our fauna, though I am not sure. It has been taken in 
Sonora, Mexico, and attributed to Southern Arizona. 
We had an interesting visitation during a violent snow¬ 
storm, which prevailed hereabouts several weeks ago, and 
which lasted forty-eight hours, accompanied by high winds. 
A trap set for Plectrophanes nivalis was found to contain a 
fine adult example of Pyranga ludoviciana, Bon. It was a 
wild bird; and its most eastern limit is the great Missouri 
plains, two thousand miles distant. Besides, on the 20th of 
January it is supposed that all these birds are in Mexico or 
Central America. How happened such a bird to reach us 
in midwinter ? Can it be that the great storm, that had been 
some ten days in approaching us, caught this bird somewhere 
on the Mexican-Gulf coast in its vortex, and compelled its 
reluctant steps to our inhospitable shores ? But I forbear, lest
