452 General Notes. [oct^ 



to be determined at such time when the specimen could be sent to Wash- 

 ington for comparison with large series. A reference to this specimen 

 appeared under the latter name in an ' Annotated List of the Water Birds 

 of Weld, Morgan and Adams Counties, Colorado,' etc., by the writer in 

 'The Auk,' Vol. XXVI, No. 3, July, 1909, p. 280. 



This specimen was recently sent to Washington and examined by Mr. 

 Harry C. Oberholser, who pronounced it Anas rubripes (formerly Anas 

 obscura), Black Duck. Believing that Dr. Dwight had, in 'The Auk,' 

 October, 1909, demonstrated that there is no subspecies of the Black 

 Duck, Mr. Oberholser made no attempt to refer it to any subspecies. 



Upon its return I took the specimen, together with Coues's and Ridg- 

 way's manuals, to the Colorado Museum of Natural History and made 

 a very careful comparison of my bird with the specimen there, which bears 

 the name, "Anas fulmgula maculosa." The comparison convinced me 

 that that specimen is also Anas rubripes. To confirm this opinion, I sent 

 to Mr. Oberholser a careful description of the bird together with a drawing 

 of its head showing patches of buff and black specking and streaking. 

 In an answer just received from him he says, "I have not much doubt 

 of its being Anas rubripes." 



It has never to my knowledge been assumed that more than one form 

 of the Black Duck exists in Colorado. That Anas rubripes is found here 

 is now positive, and until some other form is proved to be co-existent, the 

 Black Ducks of our State should be referred to this form. — A. H. Felger,

The Blue-winged Teal in Cuba in Sunamer. — I beg to report that 

 on June 12, 1910, while collecting in a brackish lagoon named "Laguna de 

 Manati," which lies on the bay about 4 leagites from the town of Guan- 

 tanamo, I saw three Blue-winged Teal (Querquedula discors), two males 

 and a female, swimming in the lagoon. Thinking they might be wounded 

 birds and unable to fly I waded in after them and was very much sur- 

 prised to see all of them take to wing and fly off, finally circling again over 

 the place where I stood and lighting on the other side of the mangroves 

 which surround the lagoon. I have not had time to return to the lagoon 

 since, so do not know how long they remained there. — Charles T. Rams- 

 den, Guantanamo, Cuba. 



The Turnstone at Grosse Isle, Michigan. — In April last I had some 

 dredging done along the river front bordering my place on Grosse Isle 

 which resulted in a bank being thrown up along the shore for some dis- 

 tance and reaching well out into the river. Here it was washed down by 

 the waves almost to the water's surface, forming, in some places, a rather 

 muddy little flat. On May 29, 1910, I happened to see a flock of waders 

 circle down to the end of the cut, and upon investigation found them to 

 be a flock of thirty Turnstones {Arenaria interpres morinella), all in rather 

 high plumage. They would bunch closely together near the water's edge,
