Coliected in abundance from a swan, probably Olor buccinator, at 
Ames, Lowa. 
It seems to me necessary, on the ground of priority, to retain the 
name given by Linnzeus, and while in my previous papers I have fol- 
lowed Piaget in accepting Giebel’s name, it was simply to avoid con- 
fusion and in deference to his authority. In the present paper, and 
with the synonomy stated in full, it seems best to restore the early name. 
While certainly recognized by Redi and Albin, Linnzeus was the first 
to properly describe it.
