 rubida, and Merganser serrator (Bay of Monterey, California), and 

 from Anas boscas, Anas carolinensis, Aythya americana, Aythya 

 affinis, and Bajila acuta (Lawrence, Kansas), and from Merganser 

 serrator (Kadiak Island, Alaska). Recorded by Osborn as "a 

 very common species on many kinds of ducks. Specimens have 

 been noted in the Cassino, Burnett, and Stejneger collections, 

 and also taken at Ames, Iowa." Recorded by Kellogg and Chap- 

 man from Aythya marila nearetica and Aythya affinis (Palo Alto, 

 California). 



Recorded by European writers from Mergus albelluSj M. merganser^ 

 Anas rufina, A. boscas, A. fuligula, A. glacialis, A. albifrons, A. 

 clypeata, A. crecca^ A. stelleri, Fuliguia marila, F. ferina, and 

 Mareca penelope. Recorded by Piaget as " sur toute espece de 

 canards." Piaget believes Docophorus natatorum Rudow,^ from 

 Platypus glacialis, Bernicla torquata, Chenalopex aegypticus, and 

 Anas fusca, to be D. icterodes. He considers D. adustus Giebel,- 

 from a domestic duck, D. brevimaculatus Giebel,'^ from Anser albi- 

 frons, and D. brunneiceps Giebel,^ from Anser cygnoides as varieties 

 merely of D. icterodes. Piaget also refers to a Docophorus, from 

 Podiceps cristatus, as a variety of icterodes.
