The xiphisternum generally ends in an expanded plate of cartilage.
Between the last sternebra and the xiphisternum two pairs articulate.
The last segment or xiphisternum (fig. 76, 4) is long and narrow, and terminates in a flattened expanded plate of cartilage.
Further back is the long sternum proper, while last comes the xiphisternum, a broad expanded plate of cartilage.
In Manis macrura the xiphisternum is drawn out into a pair of cartilaginous processes about nine inches long.
