of the primaries. The tail is forked, the outer feathers 
being about a quarter of an inch longer than the central 
ones. The beak measures five and a half lines from the 
forehead to the tip, is slender, and sharply pointed. The 
tarsi are ten lines in length ; the middle toe nearly the same ; 
the hinder toe measures eight lines, of which four belong to 
the claw. All the claws are slender and much arched ; the 
hinder one forming in the arch one third of a circle ;—thus 
admirably and beautifully is this species adapted to retain a 
safe footing upon the rocks and among the shingly localities 
in which it dwells. 
The plumage of this species is as follows :—The whole 
upper feathering, including the crown of the head and ear- 
coverts, the nape, back, scapulars, upper coverts, and the two 
middle feathers of the tail olive-brown ; the centre of the 
feathers on the back and scapulars marked with dusky streaks. 
The quill-feathers are dark-brown, with lighter edges; the 
greater and lesser coverts olive-brown, edged and tipped with 
a paler colour. The outermost feathers of the tail are dirty 
white, the rest, except the centre pair, dusky. The under 
parts of the body are pale ochre-yellow, tinged with olive, and 
an obscure streak of the same passes over the eye : the 
breast is marked with dusky spots, and the flanks with long 
streaks of the same colour: the flanks and thighs are also 
tinged with olive. This species appears to undergo some 
variations of colour at different seasons, being observed to 
have most of the olive-tinge in autumn. 
We are unwilling to add another name to the long list 
already bestowed upon this bird, as tending, perhaps, to add 
to the confusion that now exists on the subject, or we 
would suggest Maritimus as a more proper trivial name for 
this species, than those it at present bears.
