(Jround color above scarlet, encircled by twenty to thirty 

 pairs of black rings. Kach pair of black rings encloses a yel- 

 low ring. The black rings are broader above. The contiguous 

 rings of the adjacent black rings become confluent on the back. 

 Often the color between the rings is homogenous. Larger 

 specimens are usually darker than smaller ones. This fusing 

 of rings of adjacent pairs does not always occur. On the same 

 snake there are frequently rings that show no indications of 

 fusing and others that become almost completely fused. The 

 scales in the yellow rings are frequently marked with black. 

 The black rings usually extend around the body. The spaces 

 on the belly between the adjacent pairs of rings are blackish.

 red plates has a black spot. The posterior parts of the oc- 

 cipitals are usually yellow. Postorbitals black. Labials 

 yellowish, sometimes two or three bordered with black. Tem- 

 porals margined with brown or black.
