Javania californica Cairns 1994

Javania californica, sp. nov

Flabellum montereyense Durham, 1947:37 (in part: paratype and 3 nontype specimens from Alb-4551; specimen from Alb-4550; 1 specimen from Alb-4553).

DESCRIPTION.—Corallum trochoid and relatively small, attached by a thick, stereome-reinforced pedicel. Largest specimen (holotype) only 12.6 × 10.7 mm in calicular diameter and 12.6 mm in height, with a pedicel diameter of 3.6 mm. Calice elliptical; calicular edge highly serrate. Theca white, porcellaneous, and relatively thin in upper corallum.

Septa hexamerally arranged in 3 complete cycles (only 24 septa) according to the formula: S1>S2>>S3. Each S1 forms a triangular apex about 1.2 mm high at calicular edge and has a straight inner edge that thickens lower in fossa. S2 also form triangular calicular apices of equal size and are about 80% width of S1, their lower, inner edges also thickened and fused with those of the S1 into a rudimentary columella. S3 much smaller, only about 20%–25% width of S2, have slightly sinuous inner edges, and form smaller calicular apices of about 0.5 mm height. Septa thin (about 0.2 mm thick) and widely spaced, separated by approximately 1.1–1.2 mm from one another. Fossa deep and elongate.
