In test cricket, what is the highest score achieved by a team where no batsman scored a half-century or century?

The highest Test total without an individual half-century is 315, by England against West Indies in Port-of-Spain in 1985-86, when the highest score was David Gower's 47. There were 59 extras, though. There have been two other totals above 300 in Tests which did not include any fifties: England's 304 against South Africa in Cape Town in 2004-05, when the highest individual score was 42 by the No. 11, Steve Harmison, and 302 by South Africa against New Zealand in Wellington in 1963-64 (highest score 44 by Peter van der Merwe).
