The 85-times capped centre, who has already captained Ireland 48 times, heads a squad of 41 players who will assemble for a week's training in Limerick from next Monday.
At the conclusion of that camp, the Ireland squad will be reduced to approximately 30 players, from which the 22-man squad to play Canada will be named.
New Ireland coach Declan Kidney said: "I am delighted that Brian has agreed to captain the squad for the Guinness Series 2008.
"I have also opted to name a bigger squad than originally anticipated so that we can continue to familiarise a largely new-look backroom staff with a wider group of players.
"Our games assume additional importance this year considering their significance as regards our seeding position going into the 2011 World Cup draw, which is being made in December.
"We are currently ranked eighth - just ahead of Scotland - so the fact that it is paramount to at least maintain a top 8 ranking, underlines the additional importance of our results against Canada, New Zealand and Argentina."
