GENUS ANTHUS, BECHST.

_Anthus_, BECHST. Gemein. Naturg. Deutschl. 1802. (Type, _Alauda

spinoletta_.)

[Line drawing: _Anthus ludovicianus._

328]

CHAR. Bill slender, much attenuated, and distinctly notched. A few

short bristles at the base. Culmen concave at the base. Tarsi quite

distinctly scutellate; longer than the middle toe; inner lateral toe

the longer. Hind toe rather shorter than the tarsus, but longer than

the middle toe, owing to the long, attenuated, and moderately curved

hind claw, which is considerably more than half the total length of

the toe. Tail rather long, emarginate. Wing very long, considerably

longer than the lengthened tail, reaching to its middle. The first

primary nearly equal to the longest. The tertials almost as long as

the primaries.

But one species of this genus belongs properly to North America,

although a second is accidental in Greenland and Alaska. The diagnoses

are as follows:—

Bill and feet blackish. Prevailing color above olive-brown.

Beneath buff. Edge and inside of wings white. Shafts of middle

tail-feathers above dark brown … _A. ludovicianus._

Bill and feet dusky flesh-color. Prevailing color above

olive-green; more distinctly streaked. Beneath greenish-white.

Edge and inside of wings greenish-yellow. Shafts of middle

tail-feathers above whitish … _A. pratensis._

ZANDER (Cabanis Journal, Extraheft I, 1853, 64) states that _Anthus

cervinus_, PALLAS, is found in the Aleutian Islands. It is described

as having

The feet yellowish-brown; the two longest under tail-coverts

with a blackish longitudinal spot; the longest tertial

almost equal to the longest primary; the shaft of the first

tail-feather mostly white; no green on the plumage; the

throat rust-color.

BALDAMUS (Naumannia, 1857, 202) says he has received _Anthus aquaticus_

and its eggs from Labrador. This statement, however, requires

verification.
