AMMOMANES GRAYI. 507 
a. In being deeper cinnamon above, the quills and coverts all 
being edged with the same dark colour. 
b. In haying the tail broadly edged and tipped with cinnamon 
rufous, the outermost feathers not paler margined, the two centre 
ones being almost entirely cinnamon, with a broad streak of greyish 
black down the middle. 
c. In haying a greyish shade on the hind neck, which is not 
seen in the winter dress. The first primary in A. ferruginea is much 
bigger, and the distance between its tips and the tip of the second 
primary is 1°5 inch, whereas in A. erythrochlamys it measures 1:°35— 
A inches ; but even this varies a good deal, and the best difference 
between the two species lies in the larger size and greyish flanks 
of A. ferruginea. 
d. In having the lores, eyebrow, sides of face and underparts 
generally washed with yellowish, and 
e. In having more numerous and more distinct brown spots on 
the chest. 
Young.—Appears to differ from the adult only in having a few 
whitish tips to the feathers of the head and scapulars, the wing- 
coverts and quills being also much paler edged.

506. Ammomanes crayt (Wahlb.) Gray’s Lark. 
The present species is smaller than either of the preceding birds, 
and has the ear-coverts whitish or slightly washed with isabelline ; 
the tail is tipped with white spots on the inner webs of the feathers. 
It appears to be confined to Damara Land. Mr. Andersson 
writes :—‘“ This Lark is found on the barren plains in the neighbour- 
hood of Walwich Bay, as well as some distance inland ; but I have 
not observed it so far east as Objimbinque. It feeds on seeds and 
insects, and is comparatively tame, but where grass abounds it is 
difficult to procure. A few individuals are usually found together.” 
Adult male.—Aboyve light sandy isabelline, not paler on the head, 
but slightly fulvescent on the hind neck; forehead, lores, and a 
tolerably defined eyebrow whitish; feathers in front of the eye 
dusky blackish; sides of face whitish, the hinder ear-coverts washed 
with isabelline; entire under surface of body whitish, slightly 
washed with isabelline on the breast, on each side of which is an 
indistinct blackish patch ; under wing-coverts white, with a very
