was very backward, and the time of the arrival of many of the species 
given can hardly be that of an average year. The notes extend 
over a period from the 27th of March until the 15th of June, and 
only those species actually noted or taken are given. In many 
cases a large series of individuals of a given species were procured, 
and these show, as may be surmised, interesting individual and 
local variation. A large number of species were doubtless over- 
looked, and quite a number had left the region before the date of 
beginning work. The country is particularly rich both in species and 
in individuals of the several kinds, and is hardly to be excelled in 
these particulars by regions bordering on the seaboard. As little 
has been done toward making any detailed report of the ornithology 
of the State, it offers an exceedingly fertile field to the naturalist.
