We consider some long multiplets describing bulk massive excitations of M-theory two-branes and IIB string three-branes which correspond to ‘nonchiral’ primary operators of the boundary OSp(8/4) and SU(2,2/4) superconformal field theories. Examples of such multiplets are the ‘radial’ modes on the branes, including up to spin 4 excitations, which may be then considered as prototypes of states which are not described by the K-K spectrum of the corresponding supergravity theories on Ad S4 × S7 and Ad S5 × S5, respectively.
