{Dendroica c(erulca). Also several specimens of Swainson's Warbler, 

 atui a large series of Bachman's Warbler, as already recorded bj Mr. Gal- 

 braith in the present number of The Auk.' Of special interest also is 

 a pair of Crossbills (iLo.v/rt CKiX'irostrd iiiiiior), taken March 27, 1S88; thej 

 are much smaller than northern birds of the same species, and the male is 

 of a darker rctl. Thc\ were pr()babl\ breil in the mountains or tablelands 

 of Kentucky or Tennessee. 



Mr. Galbraith informs me that Pine Finches and Juncos were rather 

 common winter residents at the locality in question. 



His collection contained also a Brown Thrush with a malformed bill, in 

 which the bill is slender, lengthened, and curved to the right, with the 

 upper mandible twisted [lartiall}' beneath the lower, which is considerably 

 longer than tlie upper. A Yellow-bellied Woodpecker presents a some- 

 what similar malformation, the mandibles being crossed near the base, 

 ami the lower one attenuated and greatly lengthened. 



A beautiful albino Prothonotary Warbler {^Protonoiaria rifrea) is also 

 worthy of mention. The yellow is of normal extent and intensity', but 

 the gray is entirely i-eplaced by pure white. The wings and tail are thus 

 pure white and the body deep intense yellow, the olive of the back being 

 replaced with yellow. The specimen thus looks very much like a white- 

 winged yellow Canary with a Prothonotary's bill. 



All the birds above-mentioned, except the greater part of the Bachman's 

 Warblers, have been purchased for the American Museiun of Natural His- 

 tory.— J. A. Allen, Am. Mas. Nat. HisL, Nezv Tork City. 



Observations on Bird Migration at Milwaukee. — Tiie Milwaukee Expo- 

 sition Building occupies one square, between 5th and 6th Streets east and 

 west, and State and Cedar Streets north and south. The building is lo- 

 cated about one mile west from the Lake shore, and nearly in the centre 

 of the city north and south. The main tower of the building is nearly in 

 the centre of the structure, and rises over 200 feet above the street. Dur- 

 ing the Exposition this tower is illuminated by four electric lights of 2ckx> 

 candle power each. They are lighted from 6 to 6.30 p. m. and turned out at 

 II to 11.30 p. M., according to the condition of the atmosphere. 



The weather previous to September 20-21 was exceptionally mild and 

 pleasant, and but few birds were noticed migrating, /. e., during the dav 

 time. 1 had not yet discovered that the electric lights on the tower at- 

 tracted tiie birds to any extent. September 21-22 it grew suddenly cooler 

 with raw cold north wind. On the morning of the 22d some of the em- 

 ployes of the Exposition climbed to the tower and found "lots of birds'' 

 dead. 1 procured a few of them, the rest becoming scattered before I had 

 found it out. Of this lot there were no species of those I saw, not repre- 

 sented in my list of the next day except Colaftes aunitus which I iden- 

 tified from some feathers a young lady had saved from the specimen. 



The night of September 22-23 was raw and cold, with fresh north wind, 

 and was very dark. The next morning I found the following species 

 around the lights and on the accessible roofs.
