up on wing, singing as they rise, and continue soaring till almost 
out of sight. It varies its flight sometimes to undulations, 
almost after the manner of Pipits. 
Male. Length 6 in., wing 3 T ^-, tail 2^-. 
Female. Length 6 in., wing 3^, tail 2^. 
Bill pale yellowish horn-colour, blackened on culmen, gonys, 
and tip. Legs clay colour, with blackish claws.

This is a short-bodied,robust Lark, with long crest and absurdly 
long bill. It had a heavy flight and never attained any height in 
soaring. Its song abounded in loud, though somewhat sweet, 
notes. After rising some twenty or thirty feet, while engaged in 
song, it would suddenly drop downwards, with closed wings, to 
within a few feet of the earth, and then flutter along with a lark- 
chirp to some convenient spot to drop upon. The song reminded 
me of the rambling chant of A. mongolica , for which species I 
at first mistook it. 
Male. Length 7 in., wing 4^, expanse 11^. Tail 2 T ? 0 -, 
culmen of bill 6^, to gape from forehead to end of crest 
1|. Tarsus ^)-, mid-toe, claw t 6 q ; hind-toe T 4 o, its claw 
Bill pale yellowish horn-colour. Inside of mouth yellow. 
Iris dark hazel. Ear oval, placed nearly on the same parallel 
with the eye. Legs and claws pale clay-colour. 
Female. Length 6 t L in., wing 3 t 9 q. Irides light brown. Bill 
and legs very pale flesh-brown, the former with a darker culmen. 
Claws short and pale flesh-colour. 
The long, somewhat curved bill of this species, its crested 
head and short hind claws draw it very near to the Certhilauda. 
Streak over and round the eye pale ochreous. Crest consist¬ 
ing of blackish-brown feathers margined with yellowish brown. 
Upper parts lark-like, tinged strongly on the rump and across 
the wings with rust-brown. Axillae, flanks, and greater part of 
the basal half of each quill strongly washed with rusLcolour. 
Under parts a dingy ochreous white, browner on the pectoral 
band, where frequent blackish-brown spots occur, which ex¬ 
tend somewhat obscurely up to the lower mandible and towards 
the eye.
