67. Peucaea arizonae Kiclgw. Arizona Sparrow, 



This species frequented the thick bunches of bear-grass just below 

 the lower edge of the oak belt ; they were breeding and were very 

 shy. Their habits are eminently terrestrial, and at no time did they 

 leave the ground save to perch on the lowly bear-grass stems and 

 utter a rather sweet song. Four individuals were seen, all within a 

 hundred yards of each other. Three were secured. Nowhere else 

 did I see or hear this species, though a most careful search was 

 made in the neighborhood. It is not mentioned in Mr. Scott's 

 paper. 



68. Peucaea ruficeps boucardi (fid.). Boucard's Sparrow. 



Sparingly distributed throughout the oak belt and lowest portion 

 of the pine belt. 



69. Melospiza fasciata fallax (Baird). Desert Song Sparrow. 



Found breeding only in the near vicinity of Avater in the Santa 

 Clara Valley. 



70. Pipilo maculatus megalonyx (Baird). Spurred Towhee. 

 Common in the pines and ranging up to the mountain tops. 



71. Pipilo fuscus mesoleucus (Baird), Canon Towhee, 



Abundant in the forest-clad areas as far up as the oaks reach 

 into the pines. The resemblance of this bird's song to certain notes 

 in the Cardinal's repertory is remarkable. 



*72. Pipilo aberti Baird, Abert's Towhee. 



This species very sparingly replaces the preceding in the neigh- 

 borhood of Tucson. 



73. Cardinalis cardinalis superbus Ridgw. Arizona Cardinal. 



One pair of these were secured at Tucson. No other seen. 



74. Pyrrhuloxia sinuata beckhami Ridgw. Arizona Pyrrhuloxia. 



A few were seen near Tucson in the chaparral of the Santa Clara 

 Valley. 



75. Habia melanocephala (Swains.). Black-headed Grosbeak, 



Found breeding abundantly in the Catalina pines up to very 

 high altitudes. 



76. Guiraca caerulea eurhyncha Coues. AVestem Blue Grosbeak. 



In the valley of the Santa Clara about Tucson this Grosbeak was 

 daily seen. I shot a male and female which were carrying building 

 material intc^a willow thicket on the river bank.
