274 DR. O. FINSCH ON BIRDS FROM NORTH-EASTERN 
colour, primaries brownish black, the first, second, and third white on the basal third 
of the inner web, on the remainder as well as on the secondaries the white extended 
nearly to the basal half on both webs; the seventh to the ninth primaries tipped with 
white; the secondaries brownish black with a broad white apical margin, and narrow 
pale brownish margins on the outer web; the innermost, which are prolonged secon- 
daries (tertiariis auct.), pale greyish brown, the same as the upper quill-coverts, with 
narrow paler margins; the coverts of the primaries dark brown, those of the secondaries 
of the same colour, but tipped on the end with white; the under wing-coverts white ; 
the two middle tail-feathers greyish brown, somewhat darker than the back, with paler 
margins externally; the remainder of the tail-feathers brownish black; the outermost 
white on the outer web. Bill pale horn-grey; edges of commissure whitish; legs pale 
greyish yellow. 
The description is taken from the specimen a, an undoubtedly old male. The two 
other males agree exactly, except the c, which is considerably smaller in size. The 
female, d, is similar, but shows the dark spots on the breast a little smaller.

Differs from the allied A. desertorum, Stanl. (A. bifasciata, Temm.), in being above 
decidedly pale greyish brown, not pale ferruginous or isabelline, in having the middle 
of the secondaries (to a breadth of from 10-12") black, whereas in A. desertorum the 
secondaries are white with a black cross band of about only from 4-5" in breadth, and 
chiefly in having the jugulum and breast marked with large cordiform spots, there being 
in A. desertorum some narrow dark spots visible only on the jugulum, and these being 
sometimes wanting altogether. 
Dr. von Heuglin has undoubtedly confounded this species with the true A. desertorum ; 
for he remarks that the specimens collected by him along the shores of the Red Sea 
are darker. A specimen from Arabia in the Berlin Museum (collected by Hemprich 
and Ehrenberg), which Von Heuglin considers to be the young bird, belongs clearly 
also to A. jessei. 
I name the species after my friend Mr. William Jesse, the zealous zoologist to the 
Abyssinian expedition, who has enriched in so many respects our knowledge of the 
avifauna of the Abyssinian coast-lands.—0. F. 
[I only observed this species at Zoulla and between Ain and Amba; at the latter 
place I could not shoot any. They run with great swiftness ; and their flight is singular, 
not unlike that of a Ring-Plover—W. J.]
