The diagnostic four horns on the thoracic segments are barely
visible in this image, but the chocolate colour, raised, rough lateral
stripes and ridge of low spines on the back are clearly visible.
There is also a green form, and sometimes a form showing a brown and
green mottling. Also note the pale yellow "V" on the brown head.
