hood

Then inch by inch out of the grass rose up the head and spread hood of Nag, the big black cobra, and he was five feet long from tongue to tail.

The great God Brahm put his mark upon all our people, when the first cobra spread his hood to keep the sun off Brahm as he slept.

He spread out his hood more than ever, and Rikki-tikki saw the spectacle-mark on the back of it that looks exactly like the eye part of a hook-and-eye fastening.

And if he fights--O Rikki!” He looked at the thickness of the neck below the hood, but that was too much for him; and a bite near the tail would only make Nag savage.
