Genus OENOPOPELIA. 
This genus is one created by Blanford for two birds, subspecies, 
which differ from other Doves, as shown by him in the Avifauna of 
British India: “The little Ruddy Ring-Dove is distinguished from 
all other species by its long wing, with its first primary nearly or quite 
equal to the second, and by having the sexes dissimilar in plumage.” 
He then adds: ‘‘ Two species are generally attributed to this group, 
but I cannot see that they are sufficiently distinct to deserve separa- 
tion.” There certainly is not enough difference between them to form 
two species, nor would it be correct to do so for the two intergrade 
and the Burmese form is but a geographical race, or subspecies, of the 
Indian bird. At the same time they are distinct enough to make it 
an easy matter to at once pick out specimens of either race from 
amongst a series of the two races mixed together, with the exception 
of a certain number which are to be found in the area where the two 
forms meet.
