Hemiarges paulianus trilobite cephalon from the Verulam

Hemiarges paulianus is one of the many trilobites found in the Verulam fm of Ontario, Canada. I've only found the cephalon of this species thus far as can be seen below.

I like the bumpy surface on the exterior of the cephalon. I've read where these may have had sensory hairs or other organs to help the animal find it's way. Otherwise I think it is blind as I can't see any eye structures.

My friend Joe has a complete specimen on his website here.
