Ammodromus Swaiiis.* 
Bill more or less conical and straight, with the culmeii slightly keeled at the base, and curved, and 
the sides compressed to the tip, which is acute ; the lateral margins nearly straight ; the gonys long and 
ascending ; the nostrils basal, lateral, and placed in a small groove, with the opening oval and exposed. 
Wings short, with the first quill shorter than the three next, which are of nearly equal length ; some- 
times the first and second are shorter than the third and fourth. Tail rather lengthened, and the lateral 
feathers graduated, ^yith the end of each feather sometimes acuminated. Tarsi as long as the middle 
toe, strong, and covered in front with scarcely divided scales. Toes long and slender ; the outer toe 
rather longer than the inner, and united at its base ; the hind toe long, and armed with a long, slightly 
curved, acute claw. 
The species are found in South and North America, where some inhabit the low rush-covered sea-islands, keeping 
almost continually within the boundaries of tide-water. They course along the margin and holes and interstices of the 
weeds and sea-wrack, with a rapidity equalled only by the nimblest of the sand-pipers, and very much in their manner. 
At other times they seek the rankest growth of grass and sea-weeds, and climb along the stalks of the rushes with as 
much dexterity as they run along the ground. Other species prefer the pine-barrens, where they are always seen on 
the ground, passing through the tufts of grass with great swiftness. Their food consists of sea-animals, as shrimps, 
minute mollusca, and small crabs, &c.

t Established by the Prince of Canino in 1828. Passerina of Vieillot (181fci) is synonymous. It embraces Paroaria of the Prince of 
Canino (1832), which name was changed in 1847, by M. Cabanis, to Calyptrophorus.
