2. European Skylark (Alauda arvensis). — In the U. S. 

 Agricultural Report for 1853 is an account of an importation of 

 these birds liberated near Wilmington, by a Mr. John Gorgas, who 

 believed that in the following summer they were becoming settled. 

 There is no recent reference to this bird. 



3. Starling (Sturnus vulgaris). — A male bird was shot near 

 Odessa, about 1901, from a flock that was seen several times. 



4. House Sparrow (Passer domesticus). — A pestiferous nui- 

 sance everywhere. 



In the 'List' as issued it was stated that no hemlocks had been 

 observed in Delaware. Later I found a few growing five to six 

 miles west of Wilmington on Red Clay Creek and I have recently 

 been informed that Dr. Chas. S. Sargent, in 'The Sylvia of North 

 America,' Vol. XII, p. 64, states that "Southward it ranges through 

 the Northern States to New Castle County in Delaware." 



From the foregoing notes and additional evidence, I am led to 

 believe there was good grounds for the statement made in the 

 'Preliminary List,' to the effect, that the broad waters of the Dela- 

 ware Bay, acting as a barrier, may explain the appearance of 

 certain birds, much further to the north in Delaware than they are 

 found in New Jersey and on up the Atlantic coast. The Mocking- 

 bird was noted as a case in point, and as now appears we can add 

 the Blue Grosbeak, Summer Tanager, Cerulean Warbler, Yellow- 

 throated Warbler, Prothonotary Warbler and Brown-headed 

 Nuthatch. 



These birds are all regular summer residents in southern Dela- 

 ware, and, with the exception of the Yellow-throated Warbler 

 and Brown-headed Nuthatch, are found well up into the central 

 part of the State or beyond, considerably above the latitude of 

 Cape May, N. J.; while in New Jersey I believe every one is ex- 

 tremely rare and, in later years at least, are not found in New Jersey 

 and northward except as stragglers. 



The following notes have been made since the above record was 

 read at the Annual meeting of the American Ornithologists Union, 

 Dec. 12, 1907: 



16. Hooded Merganser (Lophodytes cucullatus). — I saw 

 four of these birds on the Bay near Lewes, Dec. 29, 1907.
