agree in all essential respects with P. n. nitidus, although the coloring of their 

 upper parts is a trifle darker, and the terminal white tail band a little wider, than 

 in my types of that subspecies. The Lower California male has the abdomen 

 and flanks wholly without trace of dark bars. 



P. n. nitidus seems to be a perfectly good subspecies, although its distribution 

 is somewhat irregular and difficult to understand. It has been found in 

 Texas, Kansas, and portions of Arizona, and it probably occurs in northwestern 

 Mexico, also, although the bird of the Sierra Madre region is true nuttallii. 



Mr. Belding was doubtless right in suspecting that he heard the notes of a 

 Phalaenoptilus in the mountains of the Cape Region, for Mr. Frazar found the 

 Frosted Poor-will very common on the Sierra de la Laguna in May and June. 

 It was also noted* in July at both Pierce's Ranch and Triunfo, but not com- 

 monly at either place. A single bird, probably a migrant on its way south, 

 was heard at San Jose del Cabo on the evening of September 2. 



Mr. Frazar states that on the mountains these Poor-wills did not begin sing- 

 ing until about tlie middle of May. "Their note is a poic^oe-hoo, the first 

 syllable given loncj, the accent on the second, and the last little more than a 

 retraction of the breath. They were almost invariably in large oaks and very 

 seldom on the ground. A female shot June 6 was undoubtedly mated and 

 would have laid soon." 



Mr. Bryant records ^ P. n. californicus from Tia Juana, San Pedro Martir, and 

 Pozo G-rande. At the latter place a male was taken on March 19, 1889. 

 Poor-wills were also " heard every evening on the steep hillsides at Comondu, 

 and at various other localities," but the specimen just mentioned seems to be 

 the only one actually examined by Mr. Bryant. 



Mr. Anthony asserts that of three Poor- wills which he obtained in the north- 

 ern part of the Peninsula in 1894 " two are rather intermediate between cali- 

 fornicus and nitidus, although one was collected as far north as Burro Canon, 

 north of Ensenada. The third, No. 5,266, collected at San Fernando May 4, 

 if not true nitidus, is not far from that form." ^
