366 SPOLIA ZEYLANICA. 
Turning to the characteristics of the various genera, the 
Peacocks—Pavo—and the Jungle Fowl—Gallus—are too well 
known to require much description. The Spur Fowl— 
Galloperdix—belongs to an Indian genus, which in structure 
shows affinity with the Pheasant and Jungle Fowl, but which 
in appearance approximates to the Partridge. Of the Quail 
croup, the Chinese Quail is placed in a separate genus— 
Excalfactoria—owing to slight differences in the wing and 
tail feathers, and to the greater dissimilarity between the 
sexes in the colouration of the under parts. 
The true Quails—Coturnix—are almost unknown in Ceylon ; 
one species has recently been authenticated, while another 
may possibly occur. In parenthesis, it should be noted that 
the Bustard Quail, the “‘ Quail” of Ceylon sportsmen, is not 
a true game bird, but belongs to the next order. The Bush 
Quails—Perdicula—form another Indian genus. They are 
little larger than Quails, but rather resemble Partridges in 
their habits, structure, and unspotted eggs. The list is closed 
by the Francolins—Francolinus—a Partridge-like genus with 
many African and five Indian species, two of which are found 
within our limits.
