 row Hawks ( Subgeniis Tinnunculus ) of America, with Especial 

 Reference to the Conti7iental Species ( Falco sparverius Linn.) By 

 Edgar A. Mearns. Beginning with a synopsis of the American 

 species, the author notices the variations of plumage dependent 

 upon age, sex and season. Descriptions are given of new sub- 

 species: Falco sparverius deserticolus, Desert Sparrow Hawk, in- 

 habiting " Southwestern United States, north to northern California 

 and western Montana, south to Mazatlan in northwestern Mexico." 

 Falco sparveritis pe7iinsularis, St. Lucas Sparrow Hawk, from 

 Lower California. Falco sparverius cequatorilis, Ecuador Sparrow 

 Hawk, from Ecuador, S. Am. Dr. Mearns's paper is based upon a 

 study of 297 specimens, of which 241 are from North America north 

 of Mexico. Enough phases were noticed to afford a basis for a 

 number more subspecies, but the incipient forms have not been 

 named.
