Narrative:
On vectors to approach the approach controller cleared us a heading to join the localizer; clearance for the ILS; 4000 ft until established; contact tower at zzzzz; and 170 knots until ZZZZZ1. All of those instructions came at one time. We intercepted the glideslope at 4;000 ft and the captain continued calling for configuring for landing. Because I was performing landing flows; checking in with the tower; and the landing checklist all in succession; I didn't notice that he had begun to slow to the final approach speed prematurely. I pointed out the speed as soon as I became aware; but we were already nearing to ZZZZZ1 at this point. The captain thought we were given 170 knots until zzzzz. I think the confusion came about as there was a restriction at ZZZZZ1 and to call tower at zzzzz in the same clearance. Our final approach speed was about 140 knots and we were slowed maybe as much as 3 miles before ZZZZZ1.
