Trilobite Cryptolithus bellus Lace Collars

Here are a number Cryptolithus bellus trilobite lace collars from the Ordovician period. It is in the Kope Formation or Eden Formation found in Carroll County, Kentucky.

I wonder if the little holes are eyes are some sort of touch sensors. The Fossils of Ohio book labels this type of trilobite as blind so I wonder if they were feelers of some sort. They seem some what staggered in nature. The outer most ring is elliptical and in between the ellipses on the next row are circular shapes. On the next row, smaller circular shapes where each circle is in between a larger set of circles.

It appears that underneath the top of the collar are more circular shapes that go around the front perimeter.
