Mr Murray has now finished speaking.
Deputy Speaker Eleanor Laing has now taken over from John Bercow. She says that backbencher speeches must be limited to eight minutes due to time constraints.
First up is Bernard Jenkin, Conservative MP for Harwich and North Essex. He says that Ian Murray did the House a great service by "putting the SNP on the spot" over Full Fiscal Autonomy.
He reiterates the challenge, saying he will only give way to Alex Salmond if he will state his commitment to the policy.
In response to a question from Andrew Gwynne, Mr Murray says he would like to see "double devolution" - devolving more power from Westminster to Holyrood, and then from Holyrood to local councils in Scotland.
He says Holyrood has become one of the "most centralised" administrations in the world.
Mr Murray continues his attack on the SNP.
He says the SNP don't really want to talk about full fiscal autonomy.
"The picture is not clear, and the Scottish people deserve an answer on this broken promise," he says.
"They are unclear on the term because they are unclear on the policy," he adds.
He challenges the SNP to bring forward an amendment on the matter.
Ian Murray says that the SNP seem to be "backpedalling" on full fiscal autonomy.
He says he hopes that the House will be enlightened as to the SNP's position on the matter as the Bill progresses.
During the election campaign Conservative leader David Cameron pledged to give more powers to Scotland within 100 days of winning.
For England, the UK government will change standing orders of the House of Commons - basically the rules that govern the way laws are passed - ensuring that only MPs representing English constituencies could vote on legislation affecting England alone.
In Wales, there will be further devolution of powers, including a new reserved powers model to clarify the division of powers between the Welsh Assembly and parliament.
There is no big devolved power heading to Northern Ireland.
Alex Salmond intervenes again, saying that he has not heard anything new from Ian Murray so far.
He asks whether given Labour's defeat in Scotland at the general election, and given that Labour are currently re-evaluating many other aspects of the party, Mr Murray has anything new to offer.
Pete Wishart also intervenes to back up Mr Salmond. He says he has heard nothing to suggest Labour are doing anything to address their "catastrophic" defeat at the general election.
Mr Murray says that Mr Wishart has not listened to the last 15 minutes of his speech.
Ian Murray says that Labour will always be the "party of devolution."
He says that Scotland's place in the UK is "simply not enough" at the moment. He adds that the Bill is important because it will strengthen Scotland's place in the Union and sense of solidarity with the rest of the UK.
He says what is now needed is the "political will and imagination" to deliver a fairer Scotland.
Mr Murray takes a shot at the SNP, saying their priority seems to be "the politics of grievance and blame", and that the SNP seem "desperate to be disappointed" before the Bill has even passed.

Ian Murray, the shadow Secretary of State for Scotland, takes to the dispatch box now.
He starts his speech by congratulating the Speaker and Mr Mundell on their re-election, and the SNP on their general election victory.
He also pays tribute to his predecessor, Margaret Curran, who lost her seat.
Mr Murray says that he and Mr Mundell have something in common - that they were easy choices for their respective jobs, a reference to them both being their party's only MPs in Scotland.

Labour's Ian Murray describes David Mundell's speech on Scotland Bill as "Castro-esque". Presumably in length rather than content.
Concluding, Mr Mundell says a no vote for a referendum was not a vote for no change.
He says the challenge now is for the Scottish government "needs to set out what it will do with its new powers." He says it is time to "stop acting and start doing."
Remember you can submit your views, external on the UK Government's Scotland Bill to Devolution (Further Powers) Committee, until 14 August 2015.

Evidence should be reasonably brief and typewritten (preferably normally no more than 4-6 sides of A4 in total). These should be sent to devolutioncommittee@scottish.parliament.uk, external
In response to a question about who will pick up the bill if the Scottish Parliament overspends, Mr Mundell replies that it is the Scottish taxpayer who will pay.
In response to a question from Labour's Seema Malhotra, Mr Mundell says that it is fair to say the Scottish Parliament will have the "final say" on welfare.
He says that although welfare benefits will be set at Westminster, the Scottish Parliament will have the option to "top them up."
An SNP MP asks if this suggests that benefits are inadequate, if they need to be topped up.
Mr Mundell replies that this it is "about being responsible".
The SNP's Alex Salmond says there is a "rumour" going around that the Conservative members have been given a prompt sheet on questions to ask Mr Mundell.
Speaker Bercow tells Mr Salmond that he always enjoys his dramatic performances in the Chamber, but that there would be nothing disorderly about it even if the rumour were true.
Labour MP Andrew Gwynne asks about the impacts on the Scotland Bill changes on the rest of the UK. He singles out Air Passenger Duty (APD) and the effect this might have on regional airports in the north of England.
He says issues like these are why a constitutional convention is needed.
Mr Mundell says that other members have raised APD as an issue, and that the Treasury has established a group to consider the matter.
Kitty:, external Here Alex Salmond goes again. Cut down by Bercow. Try asking something constructive for the benefit of your constituents #ScotlandBill
Adam W:, external #ScotlandBill is the #Tories all over. Promise the earth & expect you to be grateful when they deliver a fraction of it. So predictable.
Mr Malky:, external Can you go 5 years of this? Me neither #ScotlandBill
David Mundell says that the devolution of income tax, the allocation of half of VAT revenues raised in Scotland, and the devolution of Air Passenger Duty, mean that Holyrood will have "vitally important decisions" to make.
He says that these powers will mean Holyrood will go from raising 10% of what it spends to 50%, and that this will make it one of the "most powerful devolved legislatures" in the world.
SNP MP Owen Thompson tweets:, external Mundell pledging to appease Daily Record readers was baffling and awkward, equally. Perhaps try the word electorate next time? #FYI
While Natalie McGarry, SNP MP for Glasgow tweets:, external Being debated in the chamber is the second reading of the Scotland Bill. Mundell isn't absolutely clear on much.
She continues: Fundamental misunderstanding on the Tory benches about the extent of powers offered.
