Columba aenas Linn., Syst. Ay., 10th ed., i, p. 162 (1858).
The typical form is much larger than our Indian and differs in having a grey instead of a vinous head, as well as in having a less conspicuous neck-patch. Hartert gives this bird specific rank but I consider it only a subspecies of aenas. Intermediate forms are not infrequent and the differences are all those of degree only.
