Main Qu. 'June's List- Lucky Dice', can't find the right skellies

[MollySpitfire]

I'm on the 'June's List #3' stage of the Black Pearl quest. The journal tells me to find 6 dice from Lvl 7+ skeletons, "in the jungle". My quest arrow and ray of light led me to the Governer's Garden on Port Royal, then the light led me to a cave in the garden "Murky Mire" I think. When I enter the cave the ray of light leads me right back out again. I tried killing some of the high lvl skells in the cave but that didn't register on quest journal, didn't say "checking for dice". Where is this jungle with the right skeletons that will drop the dice I need? I'm at a loss here.
