T y p e: Holotype from Eisenstadt deposited in USNM under the number 60579 (Cheetham, 1968).

M a t e r i a l: A very common species, more than 35 specimens from different sections were studied in detail.

D i a g n o s i s: Colony large, with 7 to 10 autozooecial rows on each side. Autozooecia elongate with a large aperture. Frontal wall slightly convex and smooth often with a narrower proximal part. Marginal areolar pores large, there are about 16-22 pores on the border of each autozooecium. The rows of marginal areolar pores are characteristically curved in the proximal part of the autozooecia (Pl. 98. Fig. 4). Aperture circular to laterally elongate, oval. Oral avicularia in pairs, circular (Pl. 98, Fig. 6). Ovicell rounded triangular, with radial ribs forming its frontal wall (Pl. 98, Fig. 3 and 5).

R e m a r k s: Ovicells are relatively rare, among the studied material only four colonies have ovicells. When no ovicells are present, the species is rather similar to Reussia regularis (REUSS, 1865), which differs in always having the same width of the frontal wall, while Metrarabdotos maleckii CHEETHAM, 1968 often has a narrower proximal part of the autozooecial frontal wall.
