Mr. H. Seebohm on the Genus Cursorius. 117 
It breeds in the Canary Islands, the whole of North Africa, 
and in Arabia, Persia, Beluchistan, the Punjaub, Sind, and 
Rajputana. It does not breed north of the Trans-Caucasian 
steppes, but occasionally strays into Europe. 
3. Cursorius rufus. 
BurchelTs Courser combines the two characters of having 
the hind head slate-grey and of having dark brown or black 
on the belly ; but as neither of these characters appear in 
young in first plumage, it is safer to diagnose the species by 
the pattern of colour on the secondaries, which is constant at 
all ages. The middle secondary is white, with the basal two 
thirds of the outer web and the basal third of the inner web 
brown. 
This species is confined to South Africa, where it is found 
in the Transvaal, Natal, and the Cape Colony. 
4. Cursorius senegalensis. 
Lichtenstein^ Courser is the only species of the genus 
which has a black belly , but neither white upper tail-coverts 
nor a slate-grey hind head. However, as the first and last 
of these characters are only found in adult birds, a second 
diagnosis is necessary, which will also apply to the young in 
first plumage. This is easily found in the unique pattern of 
the secondaries. The white is shaped like a thin wedge, the 
base of which runs out at the tip, whilst the thin end splits 
the brown of the inner web almost into halves. 
This species has an extensive range in the Ethiopian Region 
from Senegambia in the west to Kordofan in the east and the 
Cape Colony in the south. 
5. Cursorius coromandelicus. 
The Indian Courser, at the first glance, looks little more 
than a large form of Lichtensteins Courser ; but when 
carefully examined, it presents many important points of 
difference besides that of size. It is the only Courser 
that combines the two characters of white upper tail-coverts 
and black under wing-coverts. As both these characters are 
found in the young in first plumage, a second diagnosis is not 
necessary.
