tubercles and more or less numerous large ones, the latter 

 sometimes without definite arrangement, but most frequently 

 some of the dorsal ones fused to form short irregular glandular 

 ridges, the most constant of which are two curved ones over the 

 shoulders and one over the ear ; the dorsal ridges sometimes 

 connected to form two linear ridges from eye to lumbar 

 region ; belly inconspiciously granular, sometimes almost 

 smooth.
