more pairs of these great insect destroyers; if more than one pair, there will be continual warfare as often as one encroaches on the domains of the other. Their nests are made of strips of vegetable fibre, weeds, etc., and lined with horsehair or catkins. They are sometimes quite bulky and generally very substantially made. The three to five eggs are laid the latter part of May, and are of a creamy ground color splashed with reddish brown and lilac. Size .95 × .70. Data.--Worcester County, Massachusetts, June 3, 1895. 4 eggs. Nest 10 feet from the ground in an apple tree; made of fibres, string, rootlets and weeds, lined with horse hair. Collector, F. C. Clark.

GRAY KINGBIRD. _Tyrannus dominicensis._ Range.--West Indies; north in April to Florida and the South Atlantic States to South Carolina and casually farther. This species is slightly larger than our Kingbird, (9 inches long), grayish instead of dark drab above, white below, and without any white tip to tail. Like the common Kingbird, it has a concealed orange patch on the crown. Their habits and nesting habits are the same as those of our common bird, but the nest is not generally as well built, and nearly always is made largely of twigs. The three or four eggs have a creamy or a creamy pink ground color, spotted and blotched with dark brown and lilac, most numerously about the large end. Size 1.00 × .73. Tarpon Springs, Florida, May 28, 1802. Nest of twigs and weeds in a low bush. Collector, J. A. Southley. 446. COUCH'S KINGBIRD. _Tyrannus melancholicus couchi._ Range.--Mexico, north in summer to southern Texas. This species is very similar to the next but the throat and breast are white, and the underparts a brighter yellow. Like the other members of this genus, these build their nests in any location in trees or bushes, making them of twigs, weeds and moss. Their three or four eggs have a creamy ground with a pinkish cast and are spotted with brown and lilac. Size .97 × .12. 447. ARKANSAS KINGBIRD. _Tyrannus verticalis._ Range.--Western United States and southern British Provinces from Kansas and Minnesota west to the Pacific. This species has grayish upper parts, shading into darker on the wings and tail, and lighter on the throat and upper breast; the underparts are yellow, and there is a concealed patch of orange on the crown. They are very abundant throughout the west, where they have the same familiar habits of the eastern species, nesting in all sorts of locations such as would be used by the latter. Their nests are made of plant fibres, weeds, string, paper or any trash that may be handy, being sometimes quite bulky. Their eggs do not differ in any particular from those of the eastern bird, except that they may average a little smaller. Size .95 × .65.
