twenty-six, under the fourth toe fourteen, and on the back from — 
the parietals to a line joining the backs of the thighs are fifty- 
four. The frontal is in contact with 2-3 supraoculars but 
does not meet the frontonasal. The supralabials are 6-7, two 
and three being in contact with the posterior loreals. ‘There 
are two pairs of nuchals, two postmentals, and no postnasals.
