In September 2011, after a shedding, I photographed specimen A. There were obviously four parietal pits, of which the outer ones were less clear to be seen than the inner ones.
In November 211 the same animal shedded again, and again I took photographs. This time there were only 2 PP's, be it at the same spot as the inner ones of September. They were also clear to be seen on the head of the freshly shed snake.
