Corythospyris hispida Goll and Björklund, 1989

Description - Add description

The skeleton consists solely of a small, thin-walled cephalis. Lattice bands, bearing very fine irregularly disposed spines and perforated by small round pores, arch between the lateral margins of the basal ring and the top of the sagittal ring and frame-enlarged sagittal lattice pores on the D- and V-sides. A-spine prominent. V-spine extremely small. Three short basal spines project laterally from the D- and LL-bars.

Diagnosis:
A species of Corythospyris characterized by an enlarged pair of sagittal lattice pores on the D-side of the irregularly spinous cephalis.

Etymology:
The trivial name is the Latin word hispida, meaning hairy.

Remarks:
Corythospyris hispida differs from Corythospyris reuschi in its smaller size, the presence of chaotic lattice spines, and the absence of a lattice bar arching across the D-side of the cephalis.

Corythospyris hispida occurs in the Cyrtocapsella eldholmi Zone and i>Pseudodictyophimus horrida Zone in: Section 104-642B-21H, CC to Sample 104-642B-20H-2, 24-26 cm; and Samples 104-642C-23H-5, 24-26 cm to -20H-2, 25-27 cm. The species also ranges discontinuously in Samples 104-643A-26X-6, 105-107 cm to -12H-1, 105-107 cm.
