It is very likely that animal was one of Bill Love's animals from many years ago. There are countless photos in that book that date back to the 80's and early 90's. I know Bill took the photos of the L.g.floridana just below that one, as well as the totally patternless goini/meansi on the opposite page there too.
I have a brand new condition copy of that book that is copyright printed/published in 2003, but I have also seen this same book back in 2001 at a library that was VERY worn-out and seemed to have been repaired several times before. It seemed to be many years old. I am thinking it has been re-published quite a few times in past years, and that the animal in question might not even be alive now, but who knows. You might try contacting Bill Love about this, as he would more than likely know about that animal's history and/or origin.
BTW, that huge 20 foot long, 250 lb. Reticulated Python on page 49 was found just a couple miles from where I used to live in Ft. Lauderdale for most of my entire life. That thing had more Raccoons to munch on there in that park than you could possibly shake a stick at, and it's huge girth is absolute proof of this.
Anyway,if you email Bill, he would very likely be able to fill you in on that animal if anyone could.
good luck!
