0 the small, round part in the middle of the belly that is left after the umbilical cord (= the long tube of flesh joining the baby to its mother) has been cut at birth: --
It is very shining, ashen-whitish, painted with light yellowish to light brown confluent flammules above and at the umbilicus.
The small umbilicus is deep and narrow and has a marginal callus.
The umbilicus is covered with a white callus.
The parietal callus is glossy and delicate, and has a node that projects towards the umbilicus.
The callus is white, small, partly concealing the umbilicus.
On the underside there is a large brown callus which partly blocks the umbilicus of the shell.
The shape of the umbilicus of a newborn baby would be discussed at length.
Those of the more central cord are smaller, and the innermost two are strongly beaded, the inner one borders the umbilicus.
