This interesting species has most of its structural characters similar to the Plovers, but has more the appearance and habits of the Rails. They are about eight inches long, the head and neck are black, the body chestnut, and the wings largely greenish yellow. They have long legs, long toes and extremely long toe nails, a scaly leaf on the forehead, and a sharp spur on the shoulder of the wing. Owing to their long toes and nails, they are enabled to walk over floating weeds and rubbish that would sink beneath their weight, otherwise. They build their nests on these little floating islands in the marsh; they are also sometimes made of weeds and trash on floating lily pads. They lay from three to five eggs of a yellowish olive color, curiously scrawled with brown and black. Size 1.22 × .95. Data.--Tampico, Mexico, June 3, 1900. Three eggs. Nest of weeds and drift on lily leaf floating in fresh water pond near town.

Family TETRAONIDAE The members of this family are birds of robust form, subdued (not brightly colored) plumage, comparatively short legs and necks; the tarsi and toes are feathered in the Ptarmigan, the tarsi, only, feathered in the Grouse, and the tarsi and toes bare in the Partridges and Bob-whites. They feed upon berries, buds, grain and insects. 289. BOB-WHITE. _Colinus virginianus virginianus._ Range.--United States east of North Dakota and Texas and from the southern British Provinces to the Gulf coast. A celebrated "game bird" which has been hunted so assiduously in New England that it is upon the verge of extermination, and the covers have to be continually replenished with birds trapped in the south and west. They frequent open fields, which have a luxuriant growth of weeds, or grain fields in the fall. Their nests are built along the roadsides, or beside stonewalls or any place affording satisfactory shelter. The nest is made of dried grasses and is arched over with grass or overhanging leaves so as to conceal the eggs. They lay from ten to twenty pure white eggs, which are very frequently nest stained when found. Size 1.20 × .95. Often two or three broods are raised in a season, but frequently one or more broods are destroyed by rainy weather. 289a. FLORIDA BOB-WHITE. _Colinus virginianus floridanus._ Range.--This sub-species, which is found in the southern half of Florida, is very much darker than the northern Bob-white, and is numerously barred below with black. Its nesting habits and eggs are identical with those of the preceding. 289b. TEXAS BOB-WHITE. _Colinus virginianus texanus._
