The new species belongs to the Halysites species group whose tubules do not occur between every pair of adjacent corallites
, all of which are transitional between Catenipora and Halysites.
Its wall is mostly smooth, but sometimes wavy, and corallites are slightly crenulated (Pl.
Some specimens have corallites with long horizontal septal spines, which almost meet at the centre of the corallite or form different axial structures (Pl.
tubulata because they differ only in the spacing of corallites (Sokolov 1955) which is a variable character (Figs 3, 5).
6) are expressed in the spacing of corallite tabulae and tubule tabulae.
Reefs are formed from millions of corallite
"houses," which are joined like apartment buildings.
Corallite medium-sized (9-30 mm high, largest diameter 11.
Specimen R45321 is fairly small, has a rather complete corallite of straight ceratoid shape with a long fixing scar on one side of the apex, and a high calicular boss in the calice.
Solitary streptelasmatid corals with a trochoid, ceratoid or cylindrical corallite.
Polygonal corallites have 3 to 9, rarely to 10, 11 sides and they are regular or irregular in shape in transverse section.
Septa are rare or absent in some corallites whereas they are thick and abundant in others (Fig.
Corner pores connecting two corallites are common and the corner pores connecting three corallites are rare (Fig.
