. Colony often large, conical, very narrow or domed, higher than wide. Zooid orifices apparently radial, alternating with radial series of rounded avicularia. Calcification smooth. Primary orifice with a fairly deep, round- ed sinus and paired condyles, surrounded by a peristome rim; adapical pore outside peristome. Ovicells fragile, with a wide ectooecial rim and a semitransparent entooecial frontal area. Avicularia paired, lateral and slightly adapical, or in series alternating with orifices. Orientation lateral and adapical; rostrum rounded to subtriangular, bar without ligula, but with 3 or more very fine, spinous processes on the non-palatal side. Antapical surface solid, with a small, central cancellate area. Lunate pores frequent, occurring in series with the avicularia but without any accompanying small avicularia.

The avicularia appear to be unique in possessing small calcareous spine-like structures on the non-palatal side of the bar. Some zooids show evidence of the development of an ectooecial lamina surrounding the adapical pore; others appear to have also developed an entooecial layer above the pore (
