yellow on the throat and abdomen. The bill of cineritius is almost invariably 

 much narrower than that of difficilis. 



The St. Lucas Flycatcher is resident in the Cape Region, where it is not 

 uncommon. Mr. Frazar found it in the greatest ntombers on the Sierra de 

 la Laguna in May and early June. He also obtained specimens at San Jose 

 del Rancho in July and at La Paz in February and March. Mr. Bryant has 

 taken it at Comondu, and San Benito and Santa Margarita Islands, while on 

 San Pedro Martir Mr. Anthony found it "very common all over the mountain, 

 especially along the streams an<l in the willows. It was evidently nesting" at 

 the time of his " visit in May, but no eggs were taken." He also states that it 

 occurs sparingly near the mine and about the mission at San Fernando, where he 

 thinks it nests " in the thick mesquite growth." It probably replacfes E. difficilis 

 in the breeding season throughout the greater part of Lower California. 



Its summer range extends northward into southern California, where "in 

 the pine growth on Ciiymaca Peak," in San Diego County, " between the alti- 

 tudes of 4,000 feet and 6,000 feet," Mr. Anthony took several specimens, which, 

 without doubt, were breeding, during the latter part of June, 1895.

^ In retaining this name I hnve acted in opposition to the advice of my friend, 

 Mr. Nelson, who considers it a synonym of E canescens Salvin and Godman. The 

 plate and description of the latter in the Biologia Centrali-Americana certainly 

 seem to fit my bird closely. When I visited England in 1891, however, I took with 

 me either the types or typical specimens of most of the Mexican birds which I had 

 up to that time described, and slmwed them to Mr. Salvin. My impression is that 

 E. fjriseAis was among tlie number, and that Mr. Salvin passed it as distinct from 

 canescens. It is not improbable that I am mistaken in so thinking, but until the 

 matter can be definitely settled by actual comparison of specimens, it seems to me 

 wiser to retain the r\a.me (jriseus (published two months later than canescens) rather 

 than to adopt the name canescens at the risk, however slight, of having to change 

 back again later.
