The eyelids, measured longitudinally, were in some specimens exactly twice as long as in the rock-pigeon.
Hence the supposed extermination of so many species having similar habits with the rock-pigeon seems a very rash assumption.
The ribs are only seven in number, whereas the rock-pigeon has eight.
This accounts for Erskines rendering (p. 321) bghr-qar here by rock-pigeon.
The unions of the rock-pigeon and the ring-pigeon appear to be equally barren of result.
This breed is intermediate between the rock-pigeon and a very poor variety of Runt or Carrier.
Carriers also graduate through foreign breeds into the rock-pigeon.
The beak is vertically thicker, and perhaps a little broader, in proportion to that of the rock-pigeon.
The beak is longer, thicker, and broader than in the rock-pigeon, proportionally with the size of body.
The beak is proportionally only slightly shorter and rather thinner than in the rock-pigeon.
