Gastropoda - Bellerophontida - Bellerophontidae
If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.
|J. Weir 1931||The shell is large, rather thin, slightly compressed on the flanks, with narrow umbilicus. The growth lamellae run a straight, oblique course backwards from the umbilicus, curve abruptly to coalesce along the margins of the band, without, however, producing welldefined filiform ribs as in B. martini, and separate again to cross the band as imbricating scales. The ornament of the band was entirely overlooked by DE KONINCK. The band itself is rather narrow, slightly convex, and scarcely elevated above the dorsum.|
