TEOCHILUS COLUBRIS, RUBY-THROATED HUMMINGBIRD. 271 



three more. In 1858, Prof. Baird nearly doubled the number, iuclnding seven in his 

 work. In 187-2, I was enabled to recognize eleven species in the " Key" ; one of these, 

 however, was purely adventitious. Since this time, a large and beautiful species (Eii- 

 geues fuhjens) has been discovered by Mr. Henshaw to occur over our Mexican border, 

 where, doubtless, additional species will eventually be found.

No Hummers appear to have been observed by Dr. Hay den ; but two 

 certainly inhabit the Missouri region, while a third {8. rufus), if not 

 also a fourth {Stellula calliope), may occur. The present species is of 

 common occurrence in Kansas, has been taken in the Saskatchewan 

 region, and ranges also over the intermediate ground. I found it quite 

 common and breeding, at Pembina, in June.

This species, one of the several ascertained of late years to inhabit 

 the United States, long after its original description as a bird of ^lex- 

 ioo, was first entered in our fauna by Prof. Baird, upon speciiuens taken 

 at El Paso, Texas, bv Mr. J. JI. Clark. Its range was almost simulta-
