“ Heteropora similis Stoliczka, 1862 ” nomen dubium ( Fig. 1J )

Heteropora similis Stoliczka, 1862: 82 , pl. 1, fig. 9.

MATERIAL EXAMINED. — Holotype of Heteropora similis , registered as 1859/0026/0138.

DIAGNOSIS. — Small fragments of columnar colony with oval transverse section. Zooecia of two types, the larger perhaps autozooecia, the smaller probably kenozooecia. No gonozooecium.

REMARKS

Owing to very poor preservation and the absence of a gonozooecium or any other characteristic features, the specimen is unrecognizable. Ŋe arrangement of apertures on the colony surface is cerioporine, somewhat comparable with Tetrocycloecia and/or Heteropora (see Zágoršek 2003, 2010).
