214 PASSERES. ANTHUS. Rock 
It is but lately that this genus has been separated by 
BecustEeiIn and Tremmincx from that of Alauda, in which 
it was included by the earlier systematists, and where it had 
been unaccountably allowed to remain by succeeding ornitho- 
logists, although presenting characters essentially different, 
and strongly marked. 
In the conical form of the head, the general characters of 
the bill and legs, as well as in a striking similarity of manners, 
they claim a very near affinity to the Wagtails. Their food 
is of the same nature, viz. insects and worms. ‘They build 
upon the ground, and appear subject to a trifling change of 
plumage in the spring, confined principally to the region of 
the head and throat.

This species appears to have remained long either unnoticed, 
or confounded with others, by the earlier ornithologists. Mr 
LeEw1n, in his work on British Birds, first gave a figure and 
description of it, by the name of the Dusky Lark, which was 
adopted by him at the suggestion of Monracu, who seems 
to have been the first observer of its distinctive characters, 
amongst a number of larks and pipits sent to him by Dr La- 
tHAM. It afterwards appeared in the “* Index Ornithologicus,” 
under the title of Alauda obscura; and Monracu gave an ac-
