Baker (M., p. 188) states that his small series from a very- 

 limited area have very noticeable variation in the extent of the 

 markings on the head and hind-neck. On the other hand, the consi- 

 derable number listed above, with many others from Bandon, Nakorn 

 Sritamarat and Trang collected over a wide area, are very constant, 

 markings, as Harington stated, being practically absent.
