Comments

Found as surface float on the scree pile at the Windom exposure.

Possible undescribed species of genus Cyrtina. Closely resembles C. hamiltomensis, but surface is smooth and punctate, rather than covered in tiny spicules. Also differs in that extremities are slightly rounded, rather than squared, and height of interarea is equal to the width rather than smaller.
