266 TRANSACTIONS OF THE [1895 



City, shot one on his ice-pond in November, 1893. Loch 

 Raven (Dukehart); Harpers Ferry, a bunch of six, November 

 6 ('93, Fisher) ; Cumberland (Shriver). 



Aythya affinis (149). Lesser Scaup Duck. 



Arriving and departing with the former species, this is much 

 the more numerous, and both with the following, are generally 

 classed together by gunners. At Grace's Quarter, " Blackheads " 

 are recorded as being shot from October 3 ('89) to April 8 ('86) 

 and, as with all other ducks, the " Blackheads" are most numerous 

 during the fall and spring nights. On April 2 ('90, Richmond) 

 one was taken near Washington. On April 5 ('95) one was 

 taken at Cumberland (Zacharia Laney). 



Aythya collaris (150). Ring-necked Duck. 



Not very numerous. I presume it arrives with the other 

 "Blackheads." All the notes I have range between March 8 

 ('94), when one was shot at Bush River by Mr. Melville Wilson, 

 who called it a "Creek Blackhead," and April 4 ('91, Wholey), 

 when one was shot in the open river below Fort McHenry. 



Glaucionetta clangula americana (151). American Golden- 

 eye. 



Common in tidewater Maryland, from October to April, I 

 have not any extreme dates. Mr. Dukehart has frequently shot 

 them at Loch Raven and they have been taken at Hagerstown 

 on December 28, 1879, and April 15, 1883 (Small). 



Glaucionetta islandica (152). Barrow's Golden-eye. 



This northern species coming south in winter to New York, 

 has in one recorded instance straggled as far south as Maryland. 

 "A female shot on the Potomac River, opposite Washington, 

 Nov. 22, 1889, by C. Herbert, is now in the collection of 

 J. D. Figgens" (C. W. Richmond, Auk, viii, 112).
