covered entirely with elongate narrow^ strongly keeled scales, sharply 
pointed posteriorly, in nbont eighteen longttudlnnl rows in the middle

Ventral shields hirge and smooth, the middle ones square, the lateral 
ones ronndt'tl, in six longitudinal series, with ad atklitional small 
external series on each side. Three posterior very long preeanal 
shieldis, the middle one very narrow and straight, the two outer ones
