shields, which are as long as the posterior. Scales in 15 
rows. Ventrals 170; anal entire; subcaudals 52. Pale 
brown above, speckled with darker; two dorsal series of 
small dark brown spots; posterior half of each scale of the 
outer row yellowish, surrounded by crowded dark brown dots ; 
ventrals yellowish, speckled with dark brown in the middle ; 
subcaudals closely speckled with dark brown.
