Strix pratiticola (III, 13). Dr. Cooper informs us that, though most of 

 these Owls are resident in California south of latitude 35°, there is a migration 

 southward in fiill from the north. Great numbers of them appeared near San 

 Buenaventura about October 20, 1872, for a few days, and most of them went still 

 farther southward. They return north about the first of April. On the 1 2th of 

 April he found a nest built four feet up in a pepper-tree {Schimis molle), forming 

 part of a hedge, composed of coarse sticks, straws, and dry horse-dung inside, shal- 

 low but strongly built, and containing two eggs. 



Falconidce (III, 1 03). The following outlines of the Falconidce were omitted 

 in their proper places.

Chamaepelia passerina (III, 389). Dr. Cooper states that an individual of 

 this species was killed by Mr. Lorquin at San Francisco, in May, 1870. Mr. Lor- 

 quin also obtained several at San Gabriel, Los Angeles County, several years pre- 



vious. 



Tetrao obscurus (III, 421). Dr. Cooper found this species in April, 1870, 

 at the edge of the melting snow, near Cisco, about 6,000 feet altitude. They were 

 still more numerous at Emigrant Gap, 5,300 feet altitude, where snow lay only 

 in patches, and at Truckee, on the east slope, where there was no snow, and where 

 he found two of their eggs in a deserted nest within sight of the town. In July 

 he found them near Verdi, near the State line. This is the limit of their range. 

 They also~frequent the edge of perpetual snow, at an elevation of 9,000 feet, more 

 numerously than below. 



Ortyx virginianus, var. floridanus (III, 469, footnote). Specimens from 

 Miami, Fla., exhibit the peninsular extreme of this species. They are altogether 

 more like var. cuhanensis than like virginianus proper, yet they differ uniformly in
