Barrandeophyllum
Classification
Phylum:
Cnidaria
Class:
Anthozoa
Subclass:
Rugosa
Order:
Stauriida
Suborder:
Metriophyllina
Family:
Laccophyllidae
Subfamily:
Laccophyllinae
Formal Genus Name and Reference:
Barrandeophyllum POČTA, 1902, p. 190
Type Species:
B. perplexum; M; +L10077, NM, Prague; lectotype by PRANTL, 1938, p. 35. The lectotype has never been sectioned and OLIVER & GALLE (1971b, p. 89) point out that PRANTL'S concept of the species is based on POCTA'S syntypes, which mayor may not be conspecific with the lectotype. The diagnosis given below is based on PRANTL, 1938, p. 35.

Description
Solitary, small, major septa moderately thick, reaching axis in early stages, in later stages their axial edges withdrawing from axis but remaining conjoined, forming narrow aulos crossed by slightly concave tabellae, minor septa thinner, moderately long, contratingent, Km longest, cardinal septum may be longer than others; periaular tabularium biform, tabellae within contratingencies dissepimentlike, those in alternate interseptal loculi declined abaxially. Presence or absence of 'splitting' at peripheral edges of septa not noted.
