No. 201 is uniform dark brown above, with about forty pairs of small light 

 spots making a row on either side of the back. The belly is nearly covered with 

 dark brown, square, or oblong, spots. The frontal shield is longer than wide. 



No. 215 is reddish brown above, with transverse black spots which show a 

 tendency to produce bars, but are too irregular to actually do so. Each scale of 

 the ventral surface carries two lateral and one or two median large, black spots, 

 the whole forming two definite lateral stripes and a less definite median one.
