Catalog entries: Stauroxiphos

Original description: Staurosphærida with two concentric lattice-spheres and four crossed simple spines, one of which is much larger than the other three.

The genus Stauroxiphos differs from its ancestral form, Staurolonche, in the greater development of one single spine, and exhibits therefore the same relation to it that Stylostaurus bears to Staurosphaera.
