I think the majority of universities will accept a 2:1 without a Masters. Most PhDs these days are 3 years in duration, structured so that the first year is considered an "MPhil" year. At the end of the first year you write an MPhil thesis, and if this is good enough, you are then allowed to continue the next two years as your PhD.
Smilodon is correct; there are no lists. You can look in the relevant journals for advertised PhDs, or contact potential supervisors directly.
