Upper surface of body covered with minute granules intermixed with large tubercles, generally larger than the spaces between them, suboval, trihedral, and arranged in 14 or 16 pretty, regular longitudinal series.

Upper surface of body covered -with small irregular flat grannies and moderately large, trihedral, strongly keeled tubercles arranged in 14 or 16 rather irregular longitudinal series; the largest tubercles measure about one fourth the diameter of the eye.

For kinematic determinacy each leg consists of a ball set in a trihedral hole in the fixed frame, a ball joining a flat plate in the fixed frame, and a ball joining a trihedral hole in the mobile frame.

Body and limbs above with small flat granules intermixed with small roundish, keeled, subtrihedral tubercles; a series of keeled tubercles from axilla to groin, limiting the abdominal region; ventral scales cycloid, imbricate, moderately large.
