Arenaria Brisson, Ornith., i, p. 48, v. p. 132 (1760).
Type by taut., Tringa interpres Linn.
The bill in this genus at once distinguishes it from all other genera. It is conical and pointed with the culmen nearly straight; the linear nostril is situated in a groove which extends nearly half-way down the bill; the wings are long and pointed, the first primary longest; the tarsus is short, reticulated behi d a nd scutellated in front; the hind toe is well developed; there is no web between the anterior toes.
Under the rulings of the Ornithological Congress the name Armaria of 1760, which antedates Strepsilas of 1811, must be accepted, in spite of its being a generic term in botany.
The genus is found over practically the whole Northern half of the Continents of Europe and Asia, being found far South in the non-breeding season.
