Fleshrkaer Dino Question

[Belzbet]

The fleshraker dinosaur is seemingly all the rage for a druids animal companion, and they are pretty good. I was checking the creature out in MM3 while creating a villian ranger. While stating out the ranger I was calulating the companions jump skill and saw that the fleshraker has a +6 racial bonus, STR 17, and presumably 7 ranks in jump skill, however the jump skill in the description was set to +24. From my calculations the dino should have a +16 Jump skill.
+8 is not accounted for. What rule am I missing?

Creatures get a bonus to Jump if they move faster than 30 ft (I believe they move 50?)

That must be it thank you.

i believe it is +4 per 10' of base movement rate over 30, or some such.

Your Jump check is modified by your speed. If your speed is 30 feet then no modifier based on speed applies to the check. If your speed is less than 30 feet, you take a -6 penalty for every 10 feet of speed less than 30 feet. If your speed is greater than 30 feet, you gain a +4 bonus for every 10 feet beyond 30 feet.

Right at the start of the skill entry. An easy rule to miss.
