10. Mergus aviericanus — Merganser. This species has now dis- 

 appeared except as a probable migrant. I have no data since 

 1906. The High School Museum possesses a specimen taken in 

 1904. 



11. Lophodytes cucullatiis — Hooded Merganser. Never very- 

 common, this species has now entirely disappeared from the coun- 

 ty. Two mounted specimens, taken in 1894, are in the Charles 

 City High School Museum. 



12. Anas vlatyhrynclios — Mallard. This species formerly nest- 

 ed within the county (Webster). Even now it is a common mi- 

 grant passing over on its way north in the latter part of March. 



13. Anas ruhripes — Black Duck. I have but one record of the 

 occurrence of this species in Floyd county. One specimen, taken 

 near Floyd, in the spring of 1896, is now in the Charles City High 



School Museum. 



14. Nettion carolinense — Green-winged Teal. Formerly com- 

 mon (Webster) but at present a rather vmcommon migrant. Last 

 reported observation is April 3, 1916. My first date in 1914 was 

 April 24th. 



15. Querquedula discors — Blue-winged Teal. A rather uncom- 

 mon migration. Latest observations: November 26, 1915, and 

 March 27, 1916. 



16. Spatula clypeata — Shoveller. A rare migrant. One was 

 killed near Nora Springs, May, 1914. 



17. Daflla acnta — Pintail. A fairly common migrant. I ob- 

 served a small flock near Charles City, April 1, 1916, my latest 

 date.

 formerly occurred in Floyd county in large flocks, but is now al- 

 most extinct. Last observation, March, 1915; C. L. Webster. 



19. Marila. americana — Redhead. An uncommon migrant. A 

 small flock was observed near Charles City in March, 1915, by 

 John R. Waller.

 ster) ; now rare migrant. My last observation was March 23,

 observation, Floyd, March, 1915; John R. Waller. 



22. CJiaritonetta alveola — Buffle-head. Webster states that this 

 species was at one time fairly common. It is now quite rare. My 

 latest observation is April 2, 1916, two specimens, near Charles
