Orcs and Goblins!

[the witch king]

I know that for along time it has been argued that orc and goblins are one and the same thing and I for one believed this to be true but i came across this.

"A bit low for goblins, at least for the big ones," thought Bilbo, not knowing that even the big ones, the orcs of the mountains, go along at great speed stooping low with their hands almost on the ground.

It looks as though Tolkien is talking about the big ones as orcs and the little ones as goblins, once and for all orcs, goblins are they the same?
