Y. Wang et al. 2003Thin cortical test with small lattice pores and secondary spines. Inner shell has small circular to polygonal pores. Three main spines that are moderately stout, typically sub-equal in length although the third may be somewhat smaller than the other two. Main spines are strongly three-bladed and connect through to the inner shell and are disposed at approximately 120° to each other.
