Drum notation seems fairly whimsical. Certainly the 'X' means a cymbal of some sort. The notation I use, which is not universal (there probably isn't such a thing!) is hi-hat (stick) where a G note is above the stave; ride cymbal where A is (above), and crash where B is above that. Obviously all treble clef.
The closest I can get is cross stick, but that's 'X' on the D line.
The 'o' and '+' indicate open and closed hi-hat respectively, so logic says that the 'X' in the E space must be hi-hat in this incarnation.
It seems that everyone has their own drum notation - some don't even use a stave - but with a bit of intuition they're all playable - with guesswork thrown in...
Other references - bass drum is generally in F space at the bottom, and the snare on middle B line, although here, it's probably the dot on the C space. For me, the spaces are all for toms, which makes it an easy read.
