outlying part of the herony had been raided by the 
Crows and N.violacens no longer present. ‘This is

the White Clay creek; one was shot and presented 
to Dr. Ezra Michener, who preserved and kept it 
in his collection for many years; later it came into 
the collection of the Swarthmore college, where it 
was lost when the building was burned. At the 
time of this capture, most American ornithologists 
recognized with certainty but a single species—Grus 
americanus the White or Whooping Crane; and 
Barnard so listed it, doubtless with the full approval 
of his friend Michener. The latter however in his 
complete list some twenty years later, gives it as 
“Grus canadensis Sandhill Crane.’ Michener’s re- 
marks convinces one of his comparison and elimina- 
tion of G.americanus, and since he followed closely 
the nomenclature and classification of Baird, it seems 
improbable that he should have overlooked the 
“G.fraterculus’ of Cassin which refers to the Little 
Brown Crane rather than G.canadensis (Baird, 
Birds, 1858, 655) which in this instance is a 
synonym of G.mexicanus. Dr. Michener appears 
to have been an accomplished and conscientious
