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.
