Material examined. Smitt MCZ # 87, holotype, with Porina plagiopora  and Escharella pertusa  [and, not identified, a very small, abraded and skeletal colony of Puellina  ], 18 January 1869, Cast # 3, W of Tortugas, 60 fms; VMNH no. 70624, 70625; USNM no. 1283243.

Description. Colony small, unilamellar, encrusting calcareous substrata ( Fig. 17View FIGURE 17 A). Zooids oval, medium sized, about 0.50 by 0.36 mm. Orifice semicircular, proximal rim straight, 5 hollow spines around distal and lateral margins ( Fig. 17View FIGURE 17 B). Costal shield extendng over the entire frontal surface, rendering lateral margins almost invisible except at growing edge of colony. Shield composed of 10 to 16 tapering costae, arranged in radiating pattern from center to lateral edge of shield, with rows of small intercostal lacunae in between, the broad outer corners of costae thickened into rounded to conical tubercles that are almost the height of orificial spines. Smaller papillae develop from outermost intercostal pores. First pair of suboral costae forming raised, V-shaped apertural bar around large round subapertural pore ( Fig. 17View FIGURE 17 C). Cuticularised papillae occur in pore just below the apertural bar Fig. 17View FIGURE 17 C, D). Gymnocyst minimal laterally, slightly more extensive proximally. Ooecia helmet shaped, imperforate, with irregular central crest or umbo developed as somewhat stellate ridged pattern. Distolaterally oriented interzooidal avicularia with oval to rhombic cystid and elongate-triangular mandible between autozooids. Ancestrula tatiform with 11 spines; its frontal surface may become covered by a round frontal shield as colony develops ( Fig. 17View FIGURE 17 F).

Remarks. Hayward & Ryland (1998, p. 330) stated that Puellina innominata  has been erroneously recorded from almost every corner of the marine realm, but its actual geographical distribution is almost certainly limited to the northeastern Atlantic. Both the names Puellina innominata  and P. radiata  have been used for Western Atlantic material for decades. Canu & Bassler’s (1928 a, pl. 14, fig. 2) record of Puellina innominata  may pertain to P. testudinea  but the avicularia in their illustration appear more curved; their record of P. radiata  in the same publication (Canu & Bassler 1928 a, pl. 10, fig. 11) is also doubtfully P. testudinea  . Marcus (1937), who was working in Brazil, synonymized all radiata  and innominata  described from around the world as one species. However, no Western Atlantic material appears to be what we would now recognize as P. radiata  or P. innominata  . See Bishop & Househam (1987) for detailed discussion.

Distribution. Florida and Caribbean.
