Does PCI Express x16 mean x4?

Stupid question I'm sure, but I am looking at mobo's and I have a question.  I have identified a RAID controller that needs a PCIe x4 slot.  I have looked at a bunch of mobo's that have PCIe x16 slots, but nothing with PCIe x4.  Are the PCIe x16 slots capable of housing a x4 card?

Thanks

No its different.

x16 represents a sixteen-lane card or slot
x16 represents a four-lane card or slot

However they are backwards compatible. But they will run at the slower speed.

So this will run x4 lanes

After re-reading I see you first said no.  Does that mean I can't put a 4 card in a 16 slot?

Sorry mate - to clarify:

No they do not mean the same thing
Yes it can go in the same slot if it will physically fit
