In Seymour's book on page 237, there are 2 examples of PA-TZ and one example of PA-UC, all tigers.

The example shown as a variation of PA-TZ looks more like a variation of PA-UC.
PA-TZ has whiskers on the top of the head, but PA-UC does not.
The variation has no top whiskers either.

What do you think? Is it supposed to be PA-UC?
Thanks
