  We investigate the worldvolume theory that describes N coincident M2-branes
ending on an M5 brane. We argue that the fields that describe the transverse
spacetime coordinates take values in a non-associative algebra. We postulate a
set of supersymmetry transformations and find that they close into a novel
gauge symmetry. We propose a three-dimensional N=2 supersymmetric action to
describe the truncation of the full theory to the scalar and spinor fields, and
show how a Basu-Harvey fuzzy funnel arises as the BPS solution to this theory.
