The Caspian Tiger (Panthera tigris virgata)

[SvetTigr]

   
"Unlike current golden tabby tigers, the one described by Pocock was the Caspian subspecies and did not have the typical whte legs."
“Tigers” by RI Pocock, in JBNHS v.33:pt.3-4 (1929): “the red tiger, illustrated in our coloured plate….is a unique type with all the black pigment abstracted from the stripes, leaving them reddish-brown and only a little darker than the ground colour…The dressed skin of a tigress ticketed ‘Northern slopes of Mount Elburz’ and presented by Col. R.L. Kennion who told me it was presented to him by a native chief. This tiger, represented in the coloured plate, is of extreme interest. The ground colour and the pattern are as in the Afghan specimen; but there is not a trace of black on the skin, all the stripes being brown and indistinctly defined owing to their approximation to the general hue of the coat.” While this might be a golden tabby tiger, Pocock suggested that it might represent one extreme end of the variation in stripe colour that occurred in the Caspian tiger; their stripes varied from black, through various shades of brown, to paler brown.
