18th lowest score in Test Match history

Update: David Barry of Pappus' plane has made it his life mission to keep an eagle eye on all cricketing facts has pointed out an error. He says :

It's the 18th lowest score by
England in Test history. It's the 89th lowest overall.- David Barry

David, thanks for taking the time out and folks I stand corrected.

England are dismissed for 81 in 30.5 overs - their lowest-ever score against Sri Lanka and if I am not mistaken it is the 18 th lowest score in Test Match history.

Now let us hear the reasons- nay- excuses.
