Description. The head is small, short, with the snout truncated. The vertical 
plate is broad and regularly pentagonal, acute-angled posteriorly; the superior 
orbitals are elongated, quadrilateral, broader behind, narrower before, and of the 
same length as the vertical, and project but slightly over the eye. The occipital 
are large, pentagonal, and receive the acute angle of the vertical plate; the frontal 
are large, pentagonal, broad above and narrow below; the anterior frontal are 
smaller, quadrilateral, and larger below than above. The rostral plate is penta- 
gonal, blunt before, broadest and slightly concave below; there are two nasal 
plates, quadrilateral, nearly of the same form and size; one is lunated before and 
the other behind. ‘The anterior orbital plate is single, quadrilateral, slightly 
lunated behind, and large, with a square loral plate in front; there are two 
pentagonal posterior orbital, the upper rather larger; the inferior wall of the orbit 
is completed by the third and fourth labial plates, of which there are six, increasing 
in size from the snout to the angle of the mouth; the first is trapezoidal, the 
second quadrilateral, and the rest are all pentagonal. 
The nostrils are lateral near the snout, and open a little upwards and back- 
wards. The eyes are rather small, the pupil dusky, with the iris hazel. The neck 
is slightly contracted.
