To the former I shall apply the term "scales;" the latter are what I have denominated "scutes."
scutes: the chitinous shields or plates on the segments of larvae.
The mid-body region is protected by a varying number of bands of scutes united by soft skin, so as to allow of movement.
The scutes on the neck, six in number, are packed closely together, the four biggest forming a square.
The scutes of the crest exhibit only very small round and distant pits.
This appearance of thickness is enhanced by the contours of bony shell which correspond to the contours of the scutes.
All these scutes, except the anterior row, have articular facets; and all those of each row are united suturally.
Retention of scutes in terrestrial emyids and in testudinids is one of many specializations for existence on land.
Retention of scutes protects the shell of terrestrial chelonians against wear.
Wear on the shell of a box turtle reduces the thickness of scutes, as does the shedding of scutes in the aquatic emyids mentioned.
A thin platelike structure.
