I am using a PIC24FJ64GA004 micro with external crystal oscillator...
Page 10, fig 6-3 of the following says that a series resistor may sometimes be needed with an external crystal....

....though how do i know it any given crystal is "AT cut"
....for example, this CMX-7X crystal doesnt say if its "AT cut" or not.

...do you know if its "AT cut"?, and if it is, do you know what value of series resistor is needed?
