contact behind the fronto-parietal. Palpebral plates form a large oral disc
which is surrounded entirely with small granular scales; freno-rostral plate
small and quadrangular; freno-ocular large, and irregularly four-sided, with a
small quadrangular one between it and super-orbital plates ; ante-ocular scales
narrow and indistinct; the central portion of the lower eyelid formed of small
semi-pellucid plates; plates of upper lip, anterior to infra-orbital plate, five •

Inhabits the arid districts immediately beyond the northern boundary of the Colony, andis
often found on level stony surfaces devoid of soil. In these situations it may be seen during

The having only six longitudinal rows ofventral scales prevents its being confounded with
any of the yet known species. It differs also from all in having the palpebral plates forming
the disc ent,rely encircled by small granular scales; the species nearest it, in this respect, is
