Scales in the central or throat region, which are in contact with the first ventral scales of a snake's body and are flanked by the chin shields, are called gular scales. The mental groove is a longitudinal groove on the underside of the head between the large, paired chin shields and continuing between the smaller gular scales.
The shape and arrangement of scales is used to identify snake species. The shape and number of scales on the head, back and belly are characteristic to family, genus and species. Scales have a nomenclature analogous to the position on the body. In "advanced" (Caenophidian) snakes, the broad belly scales and rows of dorsal scales correspond to ...

The ventral scales number 150-164 in males and 162–200 in females. The anal scale is divided (rarely single) and the subcaudal scales are paired. Males have 54–70 ...
This snake grows to an average of about .5 to 1 m. A fossorial species, the head is wedge-shaped and narrow with little neck delineation, which makes it easy to push through the soil.
