A fine typical adult retaining much of the test. The inner whorls show the ribbing well and the outer whorl shows the transition to the final adult body chamber which is wholly smooth. Sutures including the last are visible and the last 1/10 whorl is body chamber. The unmbilical seam shows uncoiling over the last 1/4 whorl. From Oxford Clay, Lamberti Limestone, Woodham, Buckinghamshire, UK.
