Eskimo & Omaha II

Family terms are always interesting. Mallory says PIE was an Omaha II system, whereas modern English (and most European languages) are an Eskimo system.

I agree, family terms are interesting and I would like to learn more about this, but I'm not familiar (lame pun intended) with these terms - could you explain what an Omaha II and an Eskimo system are?
