9. Stelgidopteryx serripennis Baird. ROUGH- WINGED SWAL- 

 LOW. Taken at Suffleld, Conn., by Mr. E. I. Shores, June 6, 1874 

 (Purdie, Bull. Nutt. Orn. Club, II, Jan , 1877, 21), its only New England 

 record. It has been found, however, breeding at West Point, New 

 York (Mearns, Bull. Nutt. Orn. Club, III, Apr., 1878, ), and will 

 doubtless soon be added to the fauna of Massachusetts. 



10. Goniaphea csemlea Gray. BLUE GROSBEAK. This southern 

 species having been taken at Grand Menan and Calais, Maine {Board- 

 man, Proc. Bost. Soc. Nat. Hist., IX, 1862, 127) is surely to be added, 

 sooner or later, to the list o.f Massachusetts birds. Its occurrence is 

 a priori far more probable than that of many species that have been 

 found here. 



11. Perisoreus canadensis Bon. CANADA JAY. This species 

 occurs doubtless in Berkshire County as an occasional winter visitor. 



12. Tyrannus verticalis Say. ARKANSAS FLYCATCHER. This 

 species has been taken at Elliot, Maine {Bryant, Proc. Bost. Soc. Nat. 

 Hist., X, 1865, 96; Purdie, Bull. Nutt. Orn. Club, I, Sept., 1876, 73), 

 and is as likely to occur in this state as n^any western and southern 

 species that have already been taken here. 



13. Corvus ossifragus Wils. FISH CROW. Probably rare or acci- 

 dental. Although there is as yet no record of its capture within the 

 state, Mr. W. Brewster, who is familiar with the species, observed a 

 single individual in Cambridge, March 16, 1875 (Brewster, Bull. Nutt. 

 Orn. Club, I, 19). Its recent capture at West Point, N. Y., and on 

 Long Island, tends to confirm its reported occurrence in Connecticut 

 by Linsley (Am. Jour. Sci. and Arts, XLIV, 1843, 260) and render it 

 almost certain that stragglers will soon be taken here. It is so easily 

 confounded with the Common Crow, even when in hand, by ordinary 

 observers, that it may for this reason have been her etofore overlooked. 



14. Empidonax acadicus Baird. ACADIAN FLYCATCHER. Not 

 known to have been taken in the state, but it has been obtained by 

 Mr. E. I. Shores in Suffleld, Conn., within ten miles of my old collect- 

 ing ground at Springfield, Mr. Shores's specimen having been identi- 

 fied as E. acadicus by no less an authority than Mr. Robert Ridgway 

 (Merriam, Rev. Birds Conn., 1877, 58). This places the species beyond 

 question in the list of New England birds (see Brewer, Proc. Bost. 

 Soc. Nat. Hist., XVII, 1875, 452). I recorded this bird in 1864 as 

 occurring at Springfield (Proc. Essex Inst., IV, 54), but have since 

 become convinced that I mistook for it E. trailli. 



15. .2Egialite8 wilsonia Cass. WILSON'S PLOVKK. Its reported 

 occurrence in the state rest on not wholly satisfactory authority (see 

 Brewer, Proc. Bost. Soc. Nat. Hist., XVII, 1875, 452). There appears 

 to be no recent well-authenticated instance of its occurrence north of 

 Long Island.
