b (usually swap) or c (as per Olivier below).
you can see b by using the right command, for example, swapinfo:
$ swapinfo
Device 1K-blocks Used Avail Capacity
/dev/ad0s1b.eli 4194304 0 4194304 0%
( mine has .eli @ the end because it's an encrypted swap device).

indeed :) gstat shows them anyway because they are part of the GEOM subsys - u
