These were the females of the flock.

The males, however, presented an appearance altogether different, owing to the immense size of their horns.

These grew out immediately over their eyes, first curving backwards, and then forwards again, until their points nearly touched the jaws of the animals on both sides.

The horns of some were more than a yard in length, and quite half as much in circumference at the base, where they were deeply indented with ring-like grooves and protuberances, such as are seen in those of the common ram.

These huge appendages gave the creatures a singular and imposing appearance, as they stood out upon the brink of the precipice outlined against the blue sky.
