massing of birds in the south the whole theory would totter. 

 In this connection it is urged that all observers make an un- 

 usual effort to make records of abundance during the remain- 

 ing wintry months as well as during the period of migration, 

 with a view to comparing the numbers of individuals with 

 those which form an average for your vicinity in normal years. 

 The opportunity for learning something more definite about 

 the variations of abundance in birds and its relation to asso- 

 ciated phenomena is an unusual one. The editor would be 

 glad to correlate notes which may be sent to him for publica- 

 tion in the June Bulletin. 



THE BIRDS OF OHIO: CORRECTION AND NOTE. 



LYNDS JONES. 



In his Birds of North and Middle America, Prof. Robert 

 Ridgway leaves open the question of the forms of two birds 

 in the Lower Lakes region. H'e had not seen specimens from 

 the region. One of these is the Long-billed Marsh Wren and 

 the other Traill's Flycatcher. These were entered in my 

 Catalogue of the Birds of Ohio as Tchnatodytcs pahistris and 

 Einpidonax fraillii respectively, with the note that E. t. 

 alnonini might be looked for as a migrant across the state. 

 Numbers of specimens of each of these forms have since been 

 collected in various parts of the state, and it is now possible 

 to speak with certainty concerning the forms represented in 

 Ohio. Specimens of the flycatcher have been compared with 

 typical E. traillii from the western states, and have also been 

 submitted to Messrs. Brewster and Oberholser for comparison 

 with larger series of skins. The unanimous conclusion is that 

 Ohio specimens are E. t. aliionini. Alder Flycatcher, and that 

 no E. traiUli occur in the state. Likewise, the wrens have been 

 carefully compared with typical T. palusfris and prove to be 

 typical and not the Prairie form, T. p. iliaciis.
