the "Proceedings of the Boston Society of Natural History," 

 Rev. Mr, Pcabotly's Report on the " Birds of Massachusetts," 

 and a few specimens in the Cabinets of the Institute, as author- 

 ities for placing them in the Catalogue. We have also given a 

 list of the accidental visitors ; and, in an Appendix, we have 

 placed those Bird& which have been found in the State, but not 

 to our knowledge, in the County. The classification adopted is 

 that of Audubon, with the exception of the orders, which we 

 have introduced. All migratory birds which breed with us are 

 distinguished as Summer visitants. The numbers on the right 

 correspond with the specimens in the Cabinets of the Institute.
