Genus Acuticassis n. gen.

TYPE SPECIES. — Acuticassis gotica n. gen., n. sp.

ETYMOLOGY. — From the Latin acutus: pointed, acute; and cassis: helmet. Feminine gender.

DIAGNOSIS. — Test monocyrtid with a large rounded conical cephalis bearing an apical horn and three feet. Initial spicule formed of MB and spines A, D, V, two L and two l. Spines free inside cephalic cavity and connected by the arches AV, Al. lD, Ll and LV in the cephalic wall. Spine A extended into an apical horn, spines D and the two L extended into basal feet. Cephalic wall reticulate with arches of various diametre and length.

REMARKS

Although the family is only known in the Middle and Upper Triassic ( Kozur & Mostler 1979, 1981), the system of arches of this new genus resembles that of Nabolella Petrushevskaya, 1981 and Fuelopicyrtis Kozur & Mostler, 1981. From the former genus, Acuticassis n. gen. differs by the lack of a thoracic skirt, from the latter by having only three feet and no secondary spines.
