CRB 83: Familiars treat Acrobatics, Climb, Fly, Perception, Stealth, and Swim as class skills.
Familiars retain their own creature types' class skill, and get the above 6 as additional class skills, right? It doesn't means "instead".
Those are the class skills for the Animal type as all the CRB regular familiars are animals.
two important parts - (bolding was added)
A familiar is an animal chosen by a spellcaster to aid him in his study of magic. It retains the appearance, Hit Dice, base attack bonus, base save bonuses, skills, and feats of the normal animal it once was, but is now a magical beast for the purpose of effects that depend on its type. Only a normal, unmodified animal may become a familiar. An animal companion cannot also function as a familiar.
Skills: For each skill in which either the master or the familiar has ranks, use either the normal skill ranks for an animal of that type or the master's skill ranks, whichever is better. In either case, the familiar uses its own ability modifiers. Regardless of a familiar's total skill modifiers, some skills may remain beyond the familiar's ability to use. Familiars treat Acrobatics, Climb, Fly, Perception, Stealth, and Swim as class skills.
by RAW it is a logical union of the two lists - original creature type and the above(Animal Type skill list) and I don't see any rules otherwise. Some new "Familiar" listings can be different listing only the base creature type skills House Centipede so your GM will have to resolve the conflict. I'd presume the Familiar entry is the monster listing which resolves the issue as you union/merge it with the 6 skills from the Animal type list.
I'll point to (PFS) Anml Companions & Familiar FAQs which can be handy.

1) Familiars are Magical Beasts not Animals. Improved familiar prevents type change to magical beast if the original creature type was not animal.
2) familiars get all class skills of their creature type.
3) the skills listed in the Familiar features are class skillls for all familiars regardless of creature type in addition to their normal class skills.
