Chasme (Fiendish Codex p. 34)

Was wondering about this neat monster. I noticed its got a Str of 19 and a BAB of +10. How does it get +17/+15/+15 con its Claws/Bite/Gore Attack? I mean it has multiattack which reduces penalty, but why +17 and not +14?

Is this a typo or am I forgetting something?

It is a typo. Actually, it should have +12 for claws and +10 for the bite and the gore.

BAB +9 Str +4 Size -1 = +12

I believe the original intent was to have this monster have many more HD than 9.
