ophidian

The pig treats the snake with disrespect, not to say insolence; nothing, ophidian or otherwise, can fascinate a pig.

Ophidian, o-fid′i-an, n. one of the true serpents, in which the ribs are the only organs of locomotion.

I have been struck, like many others, with the ophidian head and eye of the famous Rachel.

The skink of course lacks the ophidian capacity to ingest relatively enormous objects.

The Ophidian skull is also noticeable for the absence of the jugals and quadratojugals.
