This headless glyph (Qb5-135) is probably not intact. The text of Q is (intentionally?) damaged at this place. We can see something strange in 1a5:

1a5 H
1a5 P
1a5 Q

The toes are missing in the first glyph of P and an arm is missing in the second glyph of H. There is evidently a 'break' in 1a5. I think this means that the old year now has ended and I guess that in Q the 'break' was made by erasing part of Qb5-135.

The old year has traveled 12 * 30 = 360 henua days and then at the fifth following dark night there is death. Heads down. Bending too.

The leg posture of Qb5-135 is signalling something. It looks like a rhomb with an opening at the bottom.
