 tho vcrtebrals and concentric ones on the marginals, and some large

 a I -shajjcd ycUow marking on the crown ; the two broadest lateral 

 bauds usually unite behind the eye, forming a C or a large yellow 

 blotch ; the yellow bands on the chin and throat wider than the 

 interspaces between them in the young, similar to those of C. picta 

 in the adult ; limbs streaked -with yellow.
