Original Description
Shell subconical, with cervical stricture less pronounced than that at the base of thorax. Cephalis campanulate, hyaline, 0.25 as long and 0.3 as broad as the thorax, bearing 15-20 minute pores. From the apex of the cephalis arises a slightly sinuous, subvertical, rodlike apical horn three times as long as a radial apophysis. Thorax subconical, of the same length as a radial apophysis, laterally bulged especially in the lower half, bearing some 50 unequal, iregularly rounded pores with are 1-4 times as bread as the bars: its surface bears scatterd, short, slender, oblique spines. Abdomen (missing from the figured specimen) subcylindrical, extremely delicate, about half as long as the thorax and almost as broad, with relatively large subcircular pores. The three radial apophyes, arising near the base of the thorax, are straight, divergent, triangularly bladed, with the dorsal blade continued a short distance along the surface of the thorax. Cephalis 17µ long 25µ broad. Thorax 70 µ long, 78 µ broad. Length of apical horn 210 µ. Diameter of the largest thoracic pores 15.5 µ. Campbell and Clark (1944a, p. 46) describe the species from several localities of the Miocene of Southern California. Specimens from the Western Pacific sediment correspond to the Californian species in general form, and the nature of the thorax and abdomen and their pores - they differ from the latter in that the cophalis bears minute pores, the radial apophyses are less curved inwardly, and he dimensions are generally smaller.
