plastral

Variation and relative growth in the plastral scutes of the turtle Kinosternon integrum LeConte.

Siebenrock's synopsis of living trionychids was based entirely on plastral characters.

The pattern of sculpturing on the plastral bones as well as that of the carapace is generally of anastamosing ridges.

The smallest female, from Lajitas, having a plastral length of 6.9 centimeters, has a mottled carapace.

It was necessary to express plastral length as the sum of the lengths of forelobe and hind lobe.
