Using data collected with the CLEO detector operating at the CESR e+e- collider at  =3.97–4.26 GeV, we investigate 15 charmonium decay modes of the (4040), (4160), and Y(4260) resonances. We confirm, at 11 significance, the BABAR Y(4260)  +-J/ discovery, make the first observation of Y(4260)00J/ (5.1), and find the first evidence for Y(4260)K+K-J/ (3.7). We measure e+e- cross sections at =4.26 GeV as (+-J/)=58 ±4 pb, (00J/)=23 ±1 pb, and (K+K-J/)=9 ±1 pb, in which the uncertainties are statistical and systematic, respectively. Upper limits are placed on other decay rates from all three resonances.
