outer row but slightly larger. Occipital ring of the width of two scales, 

 sometimes narrower. Upper labials yellowish, like the lower jaw and 

 inferior surface of head and abdomen. A series of dark subtriangular 

 spots along- the lateral margins of the scutellfc, and in contact with the 

 dark color of the flanks. Abdomen either unicolor or provided with 

 series of similar dark spots along its middle region, from the anterior 

 third of the body to near the anus. The spots sometimes elongate 

 transversely in the shape of bars across the abdomen. 



A specimen from Anderson, South Carolina, exhibits a somewhat 

 slenderer head, and a narrower and more elongated frontal plate. 



Another very young specimen from Mississippi has a shorter head, and 

 a frontal plate proportionally much broader and shorter.
