interest that this mongrel style overruns into the Saskatchewau 

 region ; for of two species secured at the eastern base of the 

 mountains, one had the red quills and ash throat of tnexicanus, and 

 the cheek-patch mixed with red, while the other was nearly 

 pure aurdtus. {Coues.) 



This form was found breeding; in the same locality and under 

 the same conditions with pure auratus, in holes in Acer Negundo on 

 Walsh's ranch, near the mouth of Old Wives' Creek, May 30th, 

 1895. The nest contained four eggs indistinguishable from those 

 of the eastern species. Others were seen at Medicine Hat, Assa., 

 in 1894 and a number shot. Specimens were taken at Sucker 

 Creek, west end of Cypress Hills, July ist, 1895 ; later in the 

 season it was seen at Castellated Rocks in southwestern Assini- 

 bbia, in the Milk River valley ; on July 26th others were seen at 

 Lee's Creek, near Cardston, Alta.; and still later at Waterton 

 Lake, almost where Dr. Coues saw the species in 1874. 



Numerous specimens were taken at Revelstoke, B.C., in the 

 spring of 1890. These varied from almost pure auratus to pure 

 cafer. Two specimens were shot having all the characters of 

 cafer, but each had a crescentic patch of red on the nape of the 

 neck,
