occurrence for every month in the year. The representatives at both 

 places during the colder months seem to be large young birds of the year, 

 and generally young males. On the foothills of the Catalina Mountains 

 it is a common migrant, many breeding at the lower altitudes, and a few 

 ranging up to and breeding at an altitude of 4500 feet, which seems to be 

 about the limit of the vertical range. The earliest record of arrival that I 

 have in this region is February 28, 1SS5, when I took a male in full plu- 

 mage, at an altitude of a little over 3000 feet. I did not meet with another 

 until March 7 of the Name year. On the 12th of March I took a male, the 

 third of the season, and saw another male and the first female of the year. 

 By the 20th of March the arrival seemed to be general, and the birds soon 

 began nesting- On May 1, 18S5, they had generally begun building, and 

 a nest examined contained two fresh eggs. On the 4th of May of the 

 same year another nest examined contained three perfectly fresh eggs; 

 and this is the maximum number I have found. 



I met with this species at Mineral Creek, in the Pinal Mountains (alti- 

 tude about 4000 feet), in May. and again in August, hut I have not ob- 

 served it in winter on any of my visits to the valley of the San Pedro 

 River, which is in elevation about the same as Tucson, though further 

 north. The species leaves the foothills of the Catalina Mountains by 

 October 1-10. 



121. Otocoris alpestris chrysolaema. Mexican Horned Lark. — In 

 the parts of Arizona under consideration 1 have not met with any Horned 

 Lark very commonly. Mr. Brown found this form about Tucson, par- 

 ticularly in the fall and winter months. 



All the Larks that have come under my observation were on the dry 

 mesas, and I have met with them only in the fall and winter, and then 

 sparingly. 



122. Cyanocitta stelleri. Long-crested Jay. — The data in regard to 

 this species already presented to the readers of this journal (see Auk 

 Vol. II, 1885, pp. 174. .555) give all that is available as to its permanent 

 residence in the Catalinas. Generally with cold weather many repre- 

 sentatives leave the pine woods and descend as low on the foothills as an 

 elevation of 3500 feet. I noticed the birds as generally not uncommon 

 during the winters of 1SS4-85 and 1SS5-S6 in the oak region, in late 

 December and January. At other seasons they are confined to the pine 

 forests. I saw them commonly in the pines of the Pinal Mountains in 

 October. 1SS3. 



123. Aphelocoma woodhousei. Woodhouse's Jay. — A common and 

 resident species at the headwaters of Mineral Creek. Also common in the 

 foothills of the Catalinas. where it breeds. It frequently associates with 

 A. sieberii arizona:, but is not so gregarious as that species. Breeds in 

 late April and May. and I think but one brood is reared. As far as 

 I am able to judge, this species does not range below 3000 nor above 5000 

 feet in the foothills of the Catalina Mountains. I have not met with it at 

 other points than those indicated in the Pinal and Catalina Mountains.
