1. Each nave bay is separated at the vault by a transverse rib . 2. Coils are covered by moderately strong, straight transverse ribs . 3. In grosgrain, the weft is heavier than the warp, creating prominent transverse ribs . 4. The central aisle of the covered hall is covered with a barrel vault with transverse ribs . 5. The junctions are, of course, where the longitudinal and transverse ribs meet and are connected. 6. In Gothic architecture, ogives are the intersecting transverse ribs of arches that establish the surface of a Gothic vault. 7. They have shells which are discoidal to subglobular, some bearing transverse ribs and the umbilicus is generally moderate to closed. 8. The shell is more or less circular in cross section, strongly annulate with close spaced, rounded, transverse ribs . 9. The transverse ribs are pointed in the Gothic manner, and thus rise to the full height of the wider diagonal ribs. 10. The surface is usually marked by weak constrictions and is characterized at maturity by coarse transverse ribs that bifurcale or sometimes trifurcate.
