( Fig. 14 ; Table 13 )

Cribrilaria innominata: Winston & Håkansson 1986: 18 , figs 40, 42, 44. Puellina capronensis Winston, 2005: 35 , fig. 97.

Material examined. VMNH no. 610.00, holotype, Capron Shoal, near Buoy 10 A, off South Hutchinson Island, St. Lucie Co., Florida, 9 July 1998, J. E. Winston coll.; VMNH no. 70617, 70618, 70619; USNM no. 1283239, 1283240.

Description. Colonies ( Fig. 14 A) encrusting, biserial to multiserial on calcareous substrata ranging from very small sand-size grains to shells and Oculina branches. Zooids ovoid, boundaries marked by deep grooves ( Fig. 14 B, C). Orifice semicircular with 5, thick, distal spines around autozooid rims and 4 spines on ovicelled zooids. Frontal shield formed by 10–15 fused costae, with radiating rows of intercostal lacunae in between; outer edges of costae thickened and raised into tubercles, giving zooids a thick-rimmed appearance. A larger suboral foramen proximal to orifice, the first pair of costae forming a raised V below it. Ooecium helmet shaped, imperforate, with raised central keel ( Fig. 14 B, C). No avicularia. Ancestrula tatiform, with 9–11 spines (14D). Sexual reproduction may occur within five generations of ancestrula.

Distribution. East coast of Florida.
