140 Scott on Birds of Western Missouri. 



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 wei-e doubtless over- 

 looked, and quite a numlier 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 bordei'iug 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 natm'alist.
