SYNOPSES AND DESCRIPTIONS. 27 
Clouded olivaceous brown, with narrow, irregular, more or less indistinct 
vertical bands of about two scales in width, separated by narrow spaces. 
In places on the body these bands appear to meet on the back, in others 
they alternate, and posteriorly most of them are divided on the myniddle of 
the flank to form alternating series of quadrate blotches, similar to those 
of sipedon. Belly brown toward the vent, with semicircular yellow spots 
on the hinder edges of the scutes; anteriorly it is yellow, with spots of 
brown, somewhat similar in shape on the bases of the plates. There 
is great variation in intensity and amount of marking. A very large 
specimen from_ Florida shows only a narrow band of brown on the base 
of each ventral. Specimens of this species from Florida are hardly to be 
separated from tawispilotus. Ohio to Florida.
