Halysites regularis Fischer-Benzon, 1871

Strongly rounded corallites compose long, open chains or form irregular meshes, at whose sides there are 4—10 corallites. The diameter of the latter is 2.3—2.5 X 2.4—2.6 mm on the average. Walls thick. Dimensions of mesocorallites 0.4—0.5 X 0.5—0.7 mm. Intervals between tabulae about 0.5—1.0 mm, in mesocorallites about twice smaller. Septal spinules very sparse and short.
