Smittipora harmeriana (Canu & Bassler, 1929) (Fig. 5 A–C) Velumella harmeriana Canu & Bassler, 1929: p. 128. Smittipora harmeriana: Winston & Heimberg 1986, p. 11, figs 23–24; Hayward 1988, p. 281, Fig. 1c; Tilbrook 2006, p. 76, pl. 12B. Smittipora abyssicola: Harmer 1926, p. 259, pl. 16, figs 10–13; not Smittipora abyssicola (Smitt, 1873). Material examined. VNMN-0223 ( CT-2), on SEM stub; VNMN-0224, six fragments. Measurements. AzL, 0.51–0.79 (0.664 ± 0.075); AzW, 0.33–0.49 (0.429 ± 0.050); AzOpL, 0.15–0.21 (0.184 ± 0.015); AzOpW, 0.14–0.18 (0.163 ± 0.010); reproductive ZL, 0.60–0.81 (0.677 ± 0.059); reproductive ZW, 0.37–0.48 (0.426 ± 0.036); reproductive ZOpL, 0.20–0.29 (0.251 ± 0.026); reproductive ZOpW, 0.17–0.20 (0.185 ± 0.010); AvL, 0.44–0.59 (0.522 ± 0.043); AvW, 0.22–0.42 (0.305 ± 0.051); AvOpL, 0.17–0.27 (0.219 ± 0.024); AvOpW, 0.079 –0.133 (0.111 ± 0.018) (n = 15, 1). Description. Colony unilaminar, encrusting, sheet-like. Zooids irregularly semi-hexagonal proximally, rounded distally; distinct, delineated by sharp incision. Cryptocyst extensive, completely granulated, raised around margins to form rounded mural rim, depressed around and proximal to opesia, but forming broad median lip slightly turned up along proximal opesial margin, flanked by opesiular indentations. Inside opesia distally, below level of frontal surface, is a nearly semicircular shelf with straight proximal margin. Spines lacking. Opesiae campanulate in outline, dimorphic. Smaller opesiae slightly longer than broad, semicircular distally, widest proximally, with slight or marked opesiular indentations in proximolateral corners. Larger opesiae longer relative to width; opesiular indentations similarly variable. Avicularia large, interzooidal, shorter and narrower than autozooids; truncate, rounded, or triangular distally, not curved; frontal surface like that of autozooids; opesia long-oval, often widest distally, with center of opesia at or distal to center of zooid; crossbar lacking; paired condylar socket on each ...
