iu the live-oak belt on the southern slopes of the Santa Catalina 

 Mountains, forty miles north of Tucson, and part of the remaining 

 ten days iu the pine-clad region of their summits, which rise some 

 eight thousand feet above the Tucson level and five thousand above 

 the elevation at Oracle. The country covered by my rambles in- 

 cluded the central 2>art of a larger area iu Pima County, explored 

 by Mr, AV. E. D. Scott during a long residence in the Santa Catalinas. 

 For a more thorough understanding of the region in question, and 

 an excellent description of the natural characteristics of this part of 

 Arizona, I cannot do better than refer to Mr. Scott's introductory 

 paper " On the Avifauna of Pinal County," etc., published in the 

 third volume of the " Auk." 



As in the previous list, those in the subjoined, indicated by an 

 asterisk, are not re2)resented in the collection, no sjiecimens having 

 been secured. 



*1. Anas strepera Linn. GadwalL 



While exploring the upper waters of the Santa Clara, four miles 

 from Tucson, I found a duck feeding on the river and shot at it 

 but failed to kill it. Shortly after it was secured by another gunner

■ 2. Ardea herodias Linn. Great Blue Heron. 



Kare. 



*3. Ardea virescens Linn. Green Heron. 



A few noted in the valley. 

 *4."Gallinula galeata (Licht.). Florida Gallinule. 

 A pair seen on Silver Lake, near Tucson. 



■■5. Fulica americana Gmel. American Coot. 



Also seen on the Santa Clara River. 

 *6. Aegiahtis vocifera (Linn.). Kildeer. 



Kot uncommon in the Santa Clara Valley. 

 7. Callipepla squamata (Vig.). Scaled Partridge. 



Wherever found, the Scaled Quail was associated with Gambel's, 

 both on the mesas and in the lower edge of the oak-belts. One was 

 shot near the hotel at Oracle, but they rarely attain such an alti- 

 tude, even in the breeding season, and are probably induced to 

 wander awa3' from their usual haunts in search of water which is
