150 BULLETIN OF THE 



3G. Cyanospiza amceria. Common at Colorado City, and also ob- 

 served at Denver. Common in the foot-hills southwest of Denver. 



37. Pipilo erythrophthalmus, var. oregonus. Numerous among the 

 foot-hills, and more or less frequent along the streams tor ten or twenty- 

 miles to the eastward. 



38. Pipilo chlorurus. Common along the streams to some distance east 

 of the foot-hills, though it probably breeds only in the mountains. 



ICTERIDvE. 



39. Molothrus pecoris. More or less frequent. 



40. Agelaeus phoeniceus. Common about Denver. 



41. Sturnella ludoviciana, var. neglecta. Abundant. 



42. Icterus Baltimore. Moderately common along the timbered 

 streams. All the specimens examined presented an exceedingly bleached 

 and weathered appearance. 



43. Icterus spurius. Common in the vicinity of Denver. 



44. Scolecophagus cyanocephalus. Common near the streams. 



CORVIDJE. 



45. Corvus corax. Common along the Platte near Denver, and ob- 

 served at intervals along Plum Creek. 



46. Pica caudata, var. hudsonica. Seen at intervals along the 

 streams. 



4 7. Cyanurus Stelleri, var. macrolophus. The form called macro- 

 loplius was common along the streams. 



48. Aphelocoma floridana, var. Woodhousei. A single pair was 

 obtained near Colorado City, the only individuals seen. 



49. ? Picicorvus columbianus. A small party, probably of this 

 species, seen near Colorado City, but no specimens were obtained. This is 

 the species already referred to as a probably undeseribed species of wood- 

 pecker.* The colors of this species correspond very closely with the sup- 

 posed woodpecker, and having since learned that the habits of Picicorvus 

 columbianus so closely resembles those of Melanerpes torquatus as to render 

 it easily mistaken for a woodpecker, it seems more probable that it may 

 have been this bird than that a large species of woodpecker inhabiting 

 this region should have thus far been overlooked. 



TYRANNIDiE. 



50. Tyrannus carolinensis. Moderately frequent from the Soda 

 Springs northward to Denver, ranging to the base of the mountains. 



51. Tyrannus verticalis. Common at Denver, and occasionally south- 

 ward to Colorado City. Not seen in the mountains, nor in South Park.
