In this work, we consider the canonical charmonium assignments for Y(4360) and Y(4660). Y(4660) is a good candidate of 5(3)S(1) c (c) over bar state, the possibility of Y(4360) as a 3(3)D(1) cc state is studied, and the charmonium hybrid interpretation of Y(4360) cannot be excluded completely. We evaluate the e(+)e(-) leptonic widths, E1 transitions, M1 transitions and the open flavor strong decays of Y(4360) and Y(4660). Experimental tests for the charmonium assignments are suggested.
