from Palestine and the Red Sea coasts to Egypt and Nubia 
were united. In 1897 the same author separated as ‘* Ammo- 
perdia cholmleyi” the dark form from the Red Sea shores 
near Suakim, but gave as the distribution “ Hgypt and 
Nubia.” When, however, Mr. M. J. Nicoll collected a 
series in the Wadi Hof, near Cairo, he perceived at once 
that they did not belong to A. h. cholmleyi, but sent his 
specimens to me and asked me to describe them if I con- 
firmed his belief that they also differed from A. h. heyi. As 
it is, they are certainly not identical with the typical hey 
from the Sinai Peninsula and Palestine. The males differ 
in the constant absence of the white trontal band and paler 
rump and upper tail-coverts, the dusky barring of these 
parts being faint and often almost absent, while these bars 
are wider and very conspicuous in A. heyz heyi. The females 
of the Egyptian race are slightly duller, lacking the warm 
reddish tinge of the back, which has rather a faint greyish 
wash. I name this new subspecies 
Ammoperdix heyi nicolli, subsp. nov., 
in honour of its discoverer.

Though no male specimen known from Hgypt has a white 
forehead, it must be mentioned that a male from the Wadi 
Keld, near Jericho, also lacks the white frontal band, but 
the bars on its rump and upper tail-coverts are wide and 
sharply defined. All other Palestine and Sinai males have 
a conspicuous white forehead. Besides Mr. Nicoll’s specimen 
I have examined a male collected at the Wad Raschid, near 
Heluan, by Mr. J. L. Bonhote and a female in Mr. Raw’s 
collection. 
Though the discovery of this new form is due to Mr. Nicoll, 
it was apparently known long ago to Heuglin, for he says 
that it used to occur north of Assuan, and perhaps it will 
one day be found in other localities besides. .
