This closeup of the mantle shows the scattered, oval scales on the dorsal surface, and the spicules which are visible along the mantle margin.
-
The central areas of the plates have more or less longitudinal rows of shallow pits but the ridges between the pits are not prominent. This is a view of plates 2 (on left) to 6.
-
This view of the head with plates 1-2 shows the overlapping oval scales on the girdle, the globular bumps on the lateral parts of the plates, and the longitudinal ridges in the center portions of the plates which diverge anteriorly.
-
This view of the posterior end with plates 6-8 shows similar features. The longitudinal ridges in the central parts of the plates are more clearly visible here.
